Is Supermarket Fuel Inferior To Branded Fuel?

Asda forecourtFor as long as I can remember – from way before I was a driving instructor – I have repeatedly heard the old story trotted out about how supermarket fuel is of inferior quality and can damage your engine. I even got it from an Esso cashier a few years ago when I told him I could fill up at Asda for up to 10p per litre less than what the Esso garage had just hiked its prices to.

Before I go into any detail, let me just say that that claim is a load of bollocks, and is perpetuated by people who don’t have a clue.

All fuel sold in the UK must conform to EN228 or EN590 (petrol and diesel, respectively), and unless you have a car which states otherwise in the manual, it will run comfortably on fuel which meets these specifications. The only difference is that some major garages may include extra additives designed to improve performance of their basic “premium” grade (and note that I said “may”). The “super” grades definitely contain additives, along with that other “additive” of about 10p per litre on top of the forecourt displayed price. EN228 and EN590 ensure that any fuel does not damage your car, and they also ensure that you don’t get the famous “residues that gunk up your engine” crap that people love to tell you about. You can read more about it here.

There is no way that the majority of driving instructors fill up with “super”. They use regular “premium” like the rest of us. If I used “super”, my fuel bill would increase by about £500 a year.

When I drove a petrol Ford Focus, the handbook told me I needed to use a minimum of 95 RON fuel. “RON” is the Research Octane Number, and the larger the RON number, the more expensive the fuel. Normal “premium” petrol is the bog-standard grade, and is 95 RON. The higher grade 97/98 RON is the “super” type, and often has an amusing comic book name like “Super-X Excelleratium Ultra Hyper-Q Unleaded Fuel”, alongside some graphic likely to appeal to chimpanzees in fast cars. Higher performance cars tend to specify 97/98 RON as a minimum, but normal cars don’t. Unless your handbook specifically tells you to use higher than 95 RON, you will have no trouble with it. I never did.

A similar thing applies to diesel fuel. The big garages may have a “super” grade alongside the basic one, but smaller garages don’t. For the last 5 years or so, I have exclusively used Asda for my diesel fuel. I have had no engine problems, and I get excellent mileage (over 50mpg).

In 2010, while I was still driving petrol cars, I had a problem with erratic idling on my Focus (across several cars, I should add). Even the dealer tried to argue that it was down to the fuel, and advised me to use “super” and give the car a “good blow out” on the motorway. It was absolute bollocks – the pre-2013 model cars all had the same fault, and a mechanical fix was needed. But if the dealer trotted out that same crap to other owners, the myth would just get perpetuated for another generation.

Supermarket tankers fill up from the same places the bigger garages do. Sometimes, you’ll even see one of the “bigger garage” tankers delivering to a supermarket. But it all meets the EN228 and EN590 specifications.

As an additional tip, I fill up at Asda – where the fuel is always about 5p cheaper than the local garages to start with. I use an Asda Cashback+ credit card, which gives 2% cashback on all Asda purchases (including fuel), and 0.2% on all other purchases. I pay it off before any interest is charged, and since I shop at Asda anyway – spending upwards of £150 on groceries most weeks, and over £100 on fuel – cashback soon mounts up. I know 2% doesn’t sound a lot, but it is the equivalent of about 3p per litre of fuel, so if Asda is charging £1.32, I end up paying £1.29. I save at least £150 a year just based on fuel purchases, and at least double that on everything else.

But I get better mileage from the more expensive fuel

No one is saying you don’t. However, it’s only a few mpg (go on, be honest – it’s not like you double your mpg or anything), and you’re paying for it. I bet it took several tankfuls for you to work out that you were getting an improved mpg.

After all is said and done, the fuel companies want profit, and it’s the customer who provides it. So if you work it out again, I expect that you’ll be paying more for the higher-grade fuel than you’re gaining from extra mpg. If it’s a driving school car, the improved mpg will be minimal – and I know you won’t admit to that.

However, if you try to claim that the standard fuel damages your engine, you’re talking crap. If it meets the EN standards it won’t do any damage at all.

Branded fuel is better quality than supermarket fuel

Look, the tankers fill up at the same depots from the same storage tanks. The only difference is whatever the likes of Esso and Shell put in it afterwards to justify the increased price. And those additives don’t turn the fuel into Superfuel – they’re just intended to keep injectors and nozzles clean, which theoretically gives better mpg because the engine allegedly runs more smoothly. The jury is still out on whether that works or not (some people say it does, others say it doesn’t). The jury has been out for the last 30 years.

The simple fact is that any car that is less than 5-10 years old, and which has been serviced regularly, will not really see any major benefit from an additive because there’s nothing to put right. Older cars with claggy engines, maybe – just maybe – but not new ones.

The only thing that will boost your car is the octane number of the fuel. And you pay for that. The big question, though, is do you really need to?

Hello? Police? Can You Lend Me 3p?

You know how I’m always going on about the prats I have share this planet with? How about this one?

He goes into a garage and tries to put £10 of fuel in his car. He overshoots by 3p, but he doesn’t want to break into another note, and the garage won’t let him off the 3p (he’s actually got the money, remember). So what does he do? He phones the Police on 999.

Better still is the fact that he’s now gone on to Reddit to ask how he can get the Police to remove the video because it’s gone sort of semi-viral. As you can imagine, he doesn’t have much support (incidentally, to some of the smart arses on Reddit, that doesn’t sound like a Nottingham accent – more like a Derby one).

Asda To Cut Jobs?

Shopping in AsdaWell, well, well. I just did a bit of delving to find out why someone had found the blog on the search term “why is UK productivity so low”, which had thrown up an article I’d pretty much forgotten I’d written. Maybe it’s a coincidence, but I mentioned Asda in that.

Then, browsing the BBC website, I found this article which says Asda is considering cutting up to 2,500 jobs.

Asda has two problems: 1) too many chiefs, and 2) most of them are incompetent.

I shop in Asda regularly, though I am increasingly having to complete my shop elsewhere because of the stock levels. My branch is open 24 hours, but its shelf stock does not match that detail in any way, shape, or form. Asda stocks up in the middle of the night and early morning, then that’s pretty much it until the next night. On top of that, they keep running “Rollback” offers on things, and haven’t cottoned on to the fact that this encourages the owners of corner shops to come in and buy everything up so they can resell it at the RRP in their own store. By 10am, the shelves are empty of those items. I’m also pretty sure some people buy some things on Rollback to sell on Ebay at the normal price.

That’s the thing about large retailers. They can buy at much better prices than smaller sellers can, and even their normal retail prices are better than you can find in the cash & carries. Beer is a prime example – Asda’s normal prices for a case of 12 bottles are £3 – £4 cheaper than the cash & carry offers, but when they put it on Rollback, it can be as much as £10 cheaper! When that happens, even pub owners  go in and buy up stock. This Rollback discount problem also applies to many items in grocery, snacks, and confectionery.

Asda also has a problem with stock control. The amount of shelf space it gives to various products is fixed for long periods of time. So it doesn’t matter if they repeatedly sell out of one particular item (even a chimp would realise that’s because people want it), they will still maintain row after row of slower selling items, and maintain the 2 sq. ft. they allow for the item that is selling. Then, when they run out of warehouse stock, they will make no attempt to get anymore of that product until the next scheduled delivery – often weeks later. Management cannot see that if they held stock of things that sell, they would sell more of it.

Then there’s the Dairy items. I don’t piss about with low-fat stuff – if it’s got 50% less fat, it’s also got 50% less taste – yet they have shelf after shelf of that, whilst the normal-fat stuff sells out completely every day, and the shelves stay empty until the next midnight re-stock.

It’s no wonder that they’re struggling. And they’ll keep struggling until they start taking on managers who have a clue.

Ford Focus – Sticky Clutch

Slave CylinderAbout a month ago I noticed my clutch pedal on my Ford Focus 1.5TDCi felt different. It started off where as you lifted it, your foot would leave it, then the pedal jumped the last few centimetres and bounced on to your sole.

The next morning was quite cool, and after the first depression to start the car, it stuck half way down. Hooking your toes underneath and pulling it up righted it, and it would be OK for a while – but you could still feel something odd in that as you pressed it, there was initially not much tension until you’d gone several centimetres down, then it would bite.

Over the next week or so, cold mornings made it worse to start with, but pumping the pedal a few times would make it work again for a while. During a warmer period it was less noticeable, but still apparent as the day wore on. As I switched between pupils each day, I’d sometimes realise that some of them had been driving with it stuck part way down. Several of them had commented on it – one asked if I had used the dual controls a couple of times, because she’d felt the pedal move.

It went into the garage (a main dealer, as it happens) for a day, and they could feel the bounce, but I got the usual spiel that made it sound like they’d never come across it before. They bled the system (sigh) and asked me to try it for a few days. The mechanic said it might be the master cylinder. He assured me the clutch was still working fine, it was just the pedal return.To be honest, it still didn’t feel right even driving away, but after a couple of hours it was back to the way it was before, so I booked it in again. They said they’d need it for three days, and I scheduled lessons around it as necessary. It went in this week.

Before it went in, I did a bit of Googling, and it seems that this is not an uncommon problem either with Fords or various other makes. I told the dealer that when I dropped it off.

Long story short, they replaced the slave cylinder (which meant taking the gearbox out) and it is now fixed. No more clutch pedal sticking down.

I’ve seen a few instructors asking about it in various places, and a lot of normal drivers elsewhere. I wish people who haven’t got a clue wouldn’t try to behave as if they do, because some of the suggestions authoritatively given across instructor and motoring enthusiast forums are complete bollocks. It isn’t because the floor mats are jamming the pedals, and it isn’t because the dual controls are playing up. Like many such issues, it is a real fault which needs fixing properly, and a can of WD40 is unlikely to resolve it.

Note that from what I have seen on Google, this fault is absolutely not confined to Fords. Modern clutch systems are hydraulic much of the time (they used to be cable-controlled). So if you get a clutch pedal not coming all the way up, this may well be the problem you are experiencing. A slave cylinder for a Focus costs about £40 (probably more at a dealer), plus there’d be labour on top, but it’s not the end of the world in terms of total cost of repair. Fortunately, mine is covered, so I didn’t have anything to pay.

If dealers know about the problem, why don’t they fix it first time?

In many cases, it is down to warranty issues. It would appear that Ford will not cover repairs under warranty unless every possible alternative has been investigated first. Even if your bloody car is shooting flames out of the engine compartment, Ford will insist on it being checked for slight overheating until they’ll accept there is a problem – even if every Ford on the road has been doing it.

I had a similar issue recently with my new Focus (2018). The DAB radio wouldn’t remember the settings when you switched off the ignition, and Sync 3 kept locking up intermittently. My dealer wanted it in for a day to “look at it and do a Sync 3 update”.

At the time, there was no Sync 3 update – I’d been checking – so that suggestion was bullshit, and since it was intermittent, there was no way they would observe it themselves. I’d just be flinging £200 of income down the drain.

But a month or so later a Sync 3 update was issued. I installed it myself and it fixed all the problems completely. I conclude that:

  • Ford knew there was a genuine fault
  • my dealer knew there was a genuine fault
  • at the time, there was no fix
  • it needed something that didn’t exist
  • my dealer was taking the piss asking me to bring it in

In fact, it was the conversation I had with them at the time which provided me with Ford’s corporate approach to not dealing with warranty-based issues until it was absolutely unavoidable.

Right On BBC

Woman gets tattooI’d imagine that many people are aware of the BBC’s obsession with women’s rights, and its ongoing policy of generating alternative history stories to muddy the past. The one that irritates me the most is how they use every opportunity to portray Charles Babbage as secondary to Ada Lovelace. But that’s another story.

This one is a confusing piece about the suffragette movement. And one section of it concerns a woman who had a tattoo of Emmeline Pankhurst put on her leg to… well, that’s about all, really. She had a tattoo of an historical figure from Victorian England put on her leg because she’d watched the film “Suffragette”.

The first thing that jumped to my mind when I saw the photo (above) was “that looks like bloody Ada Lovelace, again”. When I saw the name, Pankhurst, I then thought “but she didn’t look like that” – a memory from my History lessons at school – so I did a quick bit of Googling.

The tattoo alongside a true imageHere, you can see the tattoo image and a photograph of Emmeline Pankhurst contemporary with the period during which she was an activist. That is the image everyone associates with Ms Pankhurst.

I’d get a refund from the tattoo parlour.

Not In My Back Yard – Or Anyone Else’s

TumbleweedIt’s funny, but I keep seeing instructors claiming on forums and social media that they all still teach turn in the road (TIR) and reversing around a corner (RRC). I mean, 99% of them are all doing it, same as they ever were.

For anyone who doesn’t know, DVSA stopped testing these manoeuvres in December 2017.

Before then, instructors would be queuing up to use corners that the examiners used. There’d sometimes be three or more cars waiting to muscle their way in (I’ve written several times about how I’d “had words” with the prats who’d tried it when I was somewhere with a pupil and they’d got in my way). A lot of them would spend a full hour there, boring their pupils witless with try after try. Right now, the only time there are any problems is in car parks used by examiners for bay parking. All the old, favourite corners and quiet roads for turning have tumbleweed blowing across them.

So I’m wondering where they’re doing these manoeuvres now, because it sure as hell isn’t in the places I go – and I travel significant distances with my pupils. I reckon I’ve seen two cars having a go in the last year – and they were private runners or PDIs by the look of them. There must be some mythical place out there, like the “elephants’ graveyard”, where all these instructors are when they reckon they’re still covering them.

I show my pupils how to do those old manoeuvres once or twice, so if something happens on their test (or once they’ve passed) and they have to turn around they’ll at least be able to physically do it (and that has happened a couple of times on tests). I bring it in sneakily, by wanting to turn round and go back the way we came for some reason, pointing out afterwards that “that used to be on the test”. That way, they realise what they’d use it for without worrying about the finer details too much, and it means they can’t accuse me of teaching them things “they don’t need”. But there’s no point spending hours on it so they can do the original ultra-polished pre-2018 test version.

What annoys me, though, is that DVSA took TIR and RRC out of the test in the first place. It was bloody obvious that instructors would gradually stop teaching them, even if they were “still on the syllabus and should be taught”, as DVSA stated. Pupils – and especially their parents – are highly likely to object to paying for lessons if they’re being taught stuff they don’t “need”, in their eyes. Christ, before any bay parking was included on tests up here, no one taught it at all. TIR and RRC are no different to that now.

What makes it all the more annoying is that it wouldn’t have cost DVSA a penny, or caused them any extra work, to keep both on the test as possible manoeuvres that could be requested, along with the newer ones. That way, instructors would have had to teach them – and pupils would have had to accept that. It would also have resulted in better trained drivers. I’d like to think DVSA will come to its senses and bring them back, because if they leave it too long it will be a major problem, since ADIs won’t remember* how to teach them properly.

Unfortunately, as with most large organisations, logic is not DVSA’s strongest point.

* You think I’m kidding? When they first introduced bay parking at one of the then two test centres in Nottingham, 80% of ADIs boycotted that one and went to the other. They didn’t know how to teach it. Several retired because of it.

Advanced Stop Lines – Say What?

Pebbles on a ropeIn this months issue of Intelligent Instructor magazine, there is an article from the RAC, the heading of which suggests that motorists could face being fined and getting points on their licences if they stop inside the cycle forward area (advanced stop lines) at traffic lights. The full RAC news release is here.

I’m absolutely in favour of that, because the number of drivers who ignore them totally – especially taxis, Audis, BMWs, motorcyclists, and other crap drivers – drives me mad. They’re there for a reason, and shouldn’t be ignored.

However, there are no links whatsoever indicating where this has come from, or how reliable it is, and the only quoted source appears to be “Olympic cyclist Sir Chris Hoy”. On top of that, motorists can already be fined for stopping in the box (see later). So you have as much balance as you’d have trying to place a rock on a tightrope. Consequently, I did a bit of Googling, and immediately came up with this article in The Sun (a UK tabloid, registered at the Post Office as a comic). This one is much more interesting.

In this article, dated only a couple of days ago (and more recent than the RAC story, which is from last week), it seems that cyclists could find themselves being fined up to £1,000 if they go over the second (stop) line. And as we all know, most of them do (the ones that don’t use the pavement at the last minute instead, then skip back on to the road once they get across the pedestrian crossings). To be fair, there are no absolute links in this article, either, though they do quote rather more balanced sources than the RAC does.

The thing is, drivers can already be fined and get points on their licence for stopping after the 1st line – and that’s official, from the police. So is the fact that cyclists can already be fined for crossing the 2nd line. It isn’t actually illegal for a motor vehicle to stop in the cycle area unless you do it after the light has changed to red – it’s not illegal if the light changes as you are passing through the box. Of course, the problem with that is that it has to be witnessed by a policeman or caught on camera.

It would appear that the only thing changing is the price list. I cannot see how they could possibly make it completely illegal for a motorist to stop in the cycle area, since there are sometimes extenuating circumstances. The one that jumps instantly to mind is on someone’s driving test – they haven’t seen a red light, the examiner uses the dual controls, and they stop in the box. It happens – it actually happened to one of mine less than a month ago – and the only alternatives would be to shoot the red and either get a prosecution notice or collide with someone, or brake so hard someone goes into the back. DVSA would love having to deal with the fallout from those.

You will also note that the cycle forward area is only for pedal cycles. Motorcycles and motor scooters are classed as motor vehicles along with cars, buses, vans, lorries, etc., and are not supposed to use them. I don’t need to point out that motorcycles and scooters routinely weave past and stop in them.

The only changes that I definitely think should be made are that cyclists get fined the same as motorists for not complying with the rules, and that enforcement is equally distributed. If the fine is increased from the current £50 for cyclists and £100 for motorists to the suggested “up to” £1,000 for everyone, and cyclists get nailed as readily as motorists, then good. And tough.

Repetitive Driving Injury (RDI)?

I originally wrote this article back in 2011 following an RAC story about bad car posture. I must confess I was dismissive of it – and still am to some extent – but my writing style has changed in the nine years that have passed. I’ve also had a string of hits on the subject recently. So an update was due.Human spine

We’ve known about repetitive strain injury (RSI) for many years. It’s where repetitive movements usually involving the hands and arms can result in tendon and muscle damage. True RSI can be a very serious and debilitating problem for some people, but there are many more people who either mistakenly attribute every ache and twinge to it, or who are just pulling a sickie at work. This is largely due to the difficulty in diagnosing it.

The RAC decided to coin a new term – repetitive driving injury, or RDI. They went on to claim it affects half of all British drivers, and said that it was due to poor posture. Symptoms apparently include foot cramps, aching sides, stiff necks, headaches, and eye strain.

Sorry, but if we are using RSI and RDI in the same breath, eye strain is not an RSI issue – if you have a rest your eyes are fine again, and you’re not going to do them any long-term damage just by using them to look at things. The same goes for cramps, aches, and stiff necks in the vast majority of cases. Yes, they might be brought on by bad posture or doing something your neck and legs aren’t used to (going on a six-hour drive, for example, when you normally don’t go further than Tesco half a mile away once a week). But again, a bit of a twinge a couple of times is not going to do you any lasting harm. Christ! I’ve lost count of the number of times I’ve pulled my back cleaning the inside of my windscreen due to leaning and stretching, and that isn’t RDI. And there is no way that “half the population” is suffering from it, when genuine RSI only occurs in up to 10% of the population.

The original eBay Motors source survey (described as “a study”, when it is merely a poll) says that it is caused by people not knowing how to adjust their seat. What? Half the population doesn’t know how to do that? It’s more a case of people choosing not to adjust their seat properly, or simply not bothering.

Every pupil I take on, I teach them the cockpit drill, and get them to adjust the seating and mirrors properly. After closing the door, the first thing they should adjust is the seat:

  • left leg should be able to push the clutch right to the floor with a slight bend at the knee (i.e. no stretching)
  • seat height should be adjusted (if possible) so that the eyes are about half-way between top of the wheel and top of the windscreen (also if possible)
  • the seat back and steering wheel position should be adjusted for optimum comfort, but so that with outstretched arms the wrists will rest on top of the steering wheel (if possible)
  • the head restraint pad should be level with your ears (if possible)

I say “if possible” in the above list, because some pupils are very short or very tall, or are carrying extra body weight, and they have to adjust things as best they can. By doing it in a structured way, the driver will not have to stretch to operate the pedals or contort themselves to operate any of the controls.

However, I have no control over them once they pass their tests, and many – the males in particular – will be intent on cultivating an image to take precedence over everything else. For example, sitting in a bucket seat in a reclined position, eyes barely level with the top of the steering wheel, right arm draped over it so they’re leaning about 20 degrees towards the middle of the car so they can see how they look in the mirror and fiddle with the stereo to find the most irritating thump-thump-thump-thump-thump track possible (or the one where they lean 20 degrees to the right, elbow on the door arm rest, stroking their bum-fluff stubble)… you see (and hear) it every day. I had one recently who, for some reason best known to himself, had decided to start changing gear by twisting his wrist round and gripping the stick from above – resulting in finding 1st instead of 3rd about 80% of the time. After I bollocked him about posing he went back to the way I’d originally taught him and the problem went away (and he passed first time a few weeks ago).

Pupils often have to be pushed into the cockpit routine for quite a while after the first lesson. A lot of them (again, mainly the males) will leap in and try to put it in gear, even though at that point they can barely reach the pedals when they’re up (and don’t get me started on the mirrors). Others (mainly the females) will insist on moving the seat so far forward that the steering wheel is literally a few centimetres from their chests, their arms are cramped right up, and the pedals are almost underneath them.

On more than one occasion a pupil has complained of cramp or leg discomfort during a lesson, even after doing proper adjustments. It’s most common with new drivers, especially when doing a manoeuvre, or if we’re driving in heavy traffic (with a lot of clutch work).

And it is not RDI.

It usually comes down to poor “driving fitness” in people who may not use their leg muscles very much. It goes away after a few lessons – though I’m sure it will come back if they start trying to “be cool” by posing once they pass.

Sticking Your Badge On The Windscreen

Self-adhesive magnetic strip tape

This time of year must be when most ADIs renew their badges judging by the traffic recently. Someone asked me the best way to mount your badge in the car.

Well, when you get your badge, they also send you a plastic wallet to put it in, and this has a sticky side so you can attach it to the windscreen. It’s fine if it’s your first one, but I hate the damned thing. It’s too big and thick, and it messes up the glass. It gets degraded by the sun, and you can’t switch it between cars (it keeps falling off if you try). And it starts to peel if you get screen cleaner anywhere near it, so the exposed sticky surface starts to attract dust and dirt and looks bloody horrible after a few months.

There are all kinds of ‘aids’ available (at relatively huge cost for what they are), such as wallets and suckers, that you can get from eBay or specialist ADI suppliers. A lot of people apparently use Blu Tac, and some even go for Sellotape or packing tape. These mess up your windscreen, too – with the added benefit being that they look like crap! And Blu Tac softens when it gets warm and your badge is likely to fall off (I once tried it for keeping cables tucked around the edge of the windscreen and found that out).

I make my own mounts. I got the idea many years ago when I installed fly screens on windows in my house. They’re attached using magnetic tape – a bit like the stuff inside fridge doors (well, a lot like it, in fact).

Magnetic tape comes in two parts – A and B – representing different magnetic poles. Basically, A is attracted to B, but A will repulse A, and B will repulse B. So, what you do is buy a length of each part, then cut four 1cm pieces of each. Stick a piece of side A in each corner of your badge (the tape has a peel-off adhesive back). Attach the four pieces of side B magnetically to these, then peel off the backing. Now push the whole thing carefully on to the windscreen where you want it (make sure the glass is clean and grease-free before you do this). You now have a secure magnetic mount, and you can easily take your badge off whenever you need to.

Magnetic tape costs as little as about £2 per metre, so £4 for a metre each of part A and part B and you’ll be set up for at least 20 badges. I don’t think many ADIs will see more than 10 – even if they do the job for their entire working lives. I’ve seen a few cars using this method now.

And Talking Of Photo ID…

I had a pupil pass his test a few weeks ago, and when he handed his licence to the examiner at the end, she looked at his photo and said “bloody hell!”

He looked nothing like it.

It turned out that when he’d applied for his provisional licence, he’d accidentally ticked “use my passport photo” – which was fine, except that he’d had his passport for six years. So his licence photo had him when he was eleven years old!

I’d picked up on the visual difference when he first started lessons with me, but he hadn’t told me the full story. I hadn’t pursued it because I’m used to people of that age looking nothing like their licence photos (even down to hair colour being different between black and blonde, or with and without tattoos and face jewellery in some cases). I usually ask them how long they were in custody for when they had it taken – pointing out that my photos are the same, and that those photo booths must have a switch inside that can be set to “NORMAL-CRIMINAL”.

I made sure he took the licence and applied for his full entitlement himself, instead of the examiner doing it. I also explained how he had to keep the photo up to date in future – renewing it every 10 years… or if he had another full-face transplant in the meantime.
