What do Tesco do to their fuel??

andygb

I should like to point out, that I have covered nearly half a million miles in a variety of cars in the past twenty years, petrol and diesel, both in the UK and on the continent, using mostly supermarket fuel, and I have NEVER had a fuelling problem.
These have included 3 BMW's, 4 Alfas, Mitsubishi, Mazda, Skoda, VW, Fords, Fiat and a Toyota.

not very professional to put a match to fuel can in front of a customer, would be sacked by all major recovery operators barr the two bit operations

What customer? Where? Maybe he is unprofessional but do no read words that are not written.

Fair comment, except:

It would be very much the manufacturer's fault if they sold those cars in France where they knew that the standard fuel available was unsuitable.

If (minimum) EN standard fuel, as sold by the supermarkets, really does give all these anecdotal problems with a modern engine then that engine shouldn't be sold in a market place where that's the only guaranteed fuel quality you can get.

Bear in mind that the EN standards are the only written standards that even BP, Esso and so on guarantee that their fuel will meet because it's the only written standard for road fuel available in the UK! They may, or may not, exceed that standard in any of a number of ways but there's no way of knowing in what way or by how much. All you know is that it's "at least" up to EN quality regardless of what pump you fill at.

If a baker baked an apple pie, I ate it and said i didnt like apples couldthe baker say its my fault?;)

Yep, and even then you'd have to allow for so many other, non-fuel-related, variables that the results probably wouldn't be conclusive!

Yes, that's why I tend to take it with a pinch of salt when someone says they put fuel X in and the car ran well, then they put in Y and immediately the car went badly. If you're within several miles of filling up, you won't be burning the new fuel, equally if the tank wasn't empty, then you're getting a blend of the two.
That's why I don't always agree with the anecdotal evidence.

(and I suspect you agree with me)

But that's the whole point -- engine manufacturers MUST engineer their products to be compatible with precisely that lowest legal specification. That is the reason we have standards.

The engine makers are relying on the fuel companies to compensate for design deficiencies by building in additives. That is not an acceptable situation -- the engines are not fit for purpose.

You are probably right. You would think that engine management systems would be able to adjust to different fuels. Obviously they can't adjust for carbon deposit build ups, but that would be gradual, over a long time.

It's probably because fuel systems run to such tight tolerances these days in the search for economy.

What the chuff are you talking about ? The anecdotal evidence im providing is from a gentleman that makes his living as a recovery technician. The cases im referring to are at various times and locations throughout his working life involving different makes and models of vehicles. I havent added anything to this, as you can tell by the lack of sensationalism in the story. Yes it is second hand but the details-of which there are few, are correct and not mistaken or altered. I have no gain from what im saying and care not if it is read or paid attention to. However i do object to your trolling response of its "b******ks". Im an adult with things to do. It appears the same is not true for you. If you wish to engage in petty name calling arguements crack on but this is not amussing me currently so i will jot be joining you. If you doubt the authenticity of my posts i can provide details of the gentleman that provided me with the above info and you can confirm it with him.

Maybe I would be more diplomatic than Jase1. But the fact remains that you lost all credibility when you said that the supermarket fuel wouldn't ignite. :rotfl::rotfl:

There are no additives added at the petrol station. They would be added at the depot.

Nope sorry, you are talking nonsense there.

Most fuel sold is from supermarkets now, I am the same as you, always used them to fuel my cars and never had a problem.

Its just scaremongering by people living in the past, the same ones that wont run their tanks empty cos they think they are getting crud into the fuel system and fill their tyres with nitrogen. Oh and Fiats are all unreliable...

I have no credibility in this matter, ive never had an issue with fuel. Im just saying what a friend of mine has told me. No one here has anymore credibility than that.
No one.:j
