Be my guest.

We both agree that the end product you buy from a supermarket pump is not the same as that from BP et al all because of these additives. .

Yes I will give you that some diesels do smell nicer than others.

Doesn't really affect the cetane of the fuel which is what provides the power and makes the car go.

Used to work in a station 70's and we had a 5* pump too for the sporty ones.

Yep, but that was different then, that was mainly down to the octane rating.

You had 2* for motorcyles, 3* and 4* for cars and I remember my old man's company Jaguar used to have the 5* to run best.

Car engines are much better these days that they'll run on virtually any grade.

But if you're doing 30,000 miles a year, then surely quality fuel would be a priority over cheap supermarket stuff? Why does nobody ever account for the future... V-Power is the cleanest, finest, engine friendly fuel on the market. When compared even with BP Ultimate, V-Power contains 50% less sulfur then Ultimate. God knows what the figures are for supermarket junk.

Over a prolonged period, cheap fuel will show it's effects. End of story.

What effects are the cheap fuel going to show, our company runs a fleet of over 200 cars, all of them do 120000 plus over 4 years and all of them run on supermarket fuel, my last car (I only had for 3 years) did 90000 on supermarket fuel and didnt have a single problem with it.

Do you work for Shell ?

I fill up with the cheapest fuel I can find

As it happens it is from a Shell petrol station - cost 128.9 on Thursday - 15 miles away but I pass it every week

Not my nearest Shell petrol station as that is charging 133.9 at the moment - though it is the cheapest in town

Fuel price variations defy logic

This is more significant than any perceived/imagined differences in the quality of the fuel - the fact that supermarkets, which squeezed out of business hundreds of small filling stations with predatory pricing policies - are now rarely the cheapest sources of fuel.

By conspiring to deprive large parts of the country of convenient filling stations, the supermarkets have done real harm to motorists - and, of course, many small business owners.

Already been proven by '5th Gear'. Shell V-Power and BP Ultimate both give an increase of 5% in power and 8% in MPG over normal branded versions.
From experience, I know that the Diesel Astra I owned would ave. 47 mpg on supermarket diesel and 54 mpg on branded im my case, Shell, as it is the nearest petrol station to me). I like to know what my fuel efficiency is, so keep records. I now drive a petrol Focus and have seen no difference in mpg between branded and supermarket.

One thing I did find in 10 years of diesel driving, if I had filled-up at a supermarket the week before the MOT, the car would always fail the emissions test, however, by driving to the nearest branded station, brimming the tank and driving back, it would then pass.

Really ?

In the last ten years of using diesels I have never had one fail emmisions and always used supermarket fuel.

My mechanic reckons if you use supermarket diesel, then you need to put in injector cleaner every 2nd fill-up to keep the engine running at maximum efficiency.

Of course, if you drive a diesel fitted with a DPF and an EGR, then the best way to boost MPG is to fit a DPF bypass kit and an EGR blanking kit.

Yet What Car? came to the opposite conclusion and said it was a waste of money!

Just look at the RON rating. Most cars will be happy on 95RON and it doesn't matter where you buy it. Most performance cars gain more power and MPG from 98RON.

i would have thought you'd save more money by adjusting your driving technique rather than paying for a "high mpg " fuel

I lol'ed at the bloke who fills up every 2 days to get a 'free' coffee.
