Supermarket fuel v the rest

System

Given that the vast majority of fuel sold in this country is from supermarkets (I recall it being around 80%) and there aren't piles of cars broken down at the roadside then clearly it isn't as bad as the more hysterical in this thread are implying.

Remember Winter diesel will be coming in soon, so it may skew your results.

No need for that, just light a small bonfire under the fuel tank to warm up its contents.

My advice is thus:

(1) If it's a lease/PCP car that goes back after 3 years run it on supermarket fuel.
(2) If you feel your car runs better on branded fuel, and you can afford it, then run it on branded fuel.

Thanks all.

Then you would be kidding yourself because it wont.

If you're down to worrying about "affording" the extra 2p or so per litre (if even that) then i would suggest you've bigger problems to worry about than "will my car run better on branded diesel?"

I'm sure this has been asked before - apologies.

OH is adamant that supermarket diesel is poor quality and bad for the engine. More than that, he prefers to use the 'premium' variety, even at the non-supermarket filling stations. Personally I'd be happy enough to use the supermarket stuff mostly because it's a lot cheaper but also because I'm at the supermarket at least once a week, whereas I have to go out of my way to go to our nearest non-supermarket one. So cheaper, and more convenient.

Is he right? Or doesn't it make that much of a difference?

Not again...........

Base fuels are exactly the same, additives and detergents vary for different customers.

A bit like whisky then - all the same.

Some folks can't tell a straight malt from a blend with 49% imported spirit made from potatoes.

Especially if they pour in in a glass with lemonade or even cola and tell you they've never had a problem getting drunk.

Similarly, some folks were convinced that their Waltham 100 jewel watch:



was better than an ordinary 17 jewel one. Jewels are like additives - if some is good, more must be better.

Only, at least in the case of that Waltham, none of the 83 "extra" jewels made any practical difference at all.

Yes, they provided a theoretical advantage in some very specific circumstances that you could design "tests" to prove - the US didn't allow the counting of jewels that never did anything - but in the real world they were completely and utterly superfluous except as a marketing claim.
