I've noticed a big difference between adsa shi7 and qualty fuel. My Dodge Caliber hated asda diesel.
I've only had my Freelander for 6 days and I wont be putting cheap diesel in it.

Must admit to not trying this 'expensive' fuel yet but reading up on it, it does claim to have benefits. I'm not interested in MPG, the only thing that would sway me is if it helps in the longevity of the working parts, eg injectors, turbo, fuel pump and so on.

The claim to 'smoothness' seems to be a cleaner more precise combustion, yet of the people who have tried it, as many say there is no noticeable difference

Is it a psychological thing, a placebo maybe where we want it to work so badly we talk ourselves into believing it's worth.

Every time I go to fill up I intend trying my local BP Ultimate, and then I bulk at the price and fill up with ordinary BP diesel.

12 months of driving nearly and it's still smooth, can get over 40mpg if I'm bored so at the moment the jury is out for me. My only concern is whether my engine needs the BP Ultimate additives for long life and I suppose if further down the line I find the turbo's variable vanes stuck up with carbon, then perhaps the Shell or BP fuel may have helped, I just dunno

To my mind, Supermarket diesel is no different to branded standard diesel, they both have no additives unlike Vpower and Ultimate. It's just that the supermarkets offer cheaper fuel to entice you into shopping as well, they all have to meet a certain grade of quality and the VPower and Ultimate exceeds that.

Perhaps at the next 'meet' we can put 'colour' and 'gear knobs' to one side and discuss the merits of this wonder fuel.

Just to add another bit of 'fuel to the fire' there is a current (and lengthy) discussion regarding putting 2-stroke oil into the cheaper diesels to make things smoother, quieter etc. I have tried all of the 'quality' diesels and have to admit that I can't tell the difference from the budget ones (apart from price of course) but adding a bit of 2-stroke oil certainly makes things quieter in the mornings. Maybe in these days of low sulphur fuels we need a little more lubrication to the pump & injectors - worth a try anyway. Cheers,

I know, that's another one I have been following with interest, I mean to try it but never do.

how can supermarket fuel differ from standard fuel i cant see how because is it all refined to the same standards after all there are only 4/5 refinerys in the uk surley they all dont have differant ways of producing fuel  rainy-city

cripes the 2 stroke thing rears it head again. this forum once had the reference thread for the 2 stroke debate, people from all over including South Africa (sadly in this case) joined in the discussion.


That thread seems to have died on here now , maybe the 2 stroke disciples are now preaching their gospel on other forums At work

I almost always use Shell. I tried VPower for about 4 tanks full but it did not seem to make any significant difference to justify the extra price. However, speaking to a Total tanker driver the other day, he says they all fill up at the same BFIs anyway - so how do the brands differ?  10MY (Sept 09) TD4 HSE Auto in Stornoway Grey (Now Gone)

I've noticed no difference with the Shell, but a definite performance improvement with BP Ultimate and also with 50% biodiesel. In both cases improvements were down to the higher cetane rating of the fuel.
I should say that this was on a Disco2 - big heavy thing with much less oomph than my FR2. I suspect the same improvements would occur in the FR2, but it's a much smoother and more responsive engine so I'm guessing improvement would be less noticeable. I have used BP Ultimate in the FR2 and it does seem to improve MPG.
I've been told that it is also beneficial if you have a DPF, which I don't

Not positive about this, but.....I beleive the difference between the petrol from each retailer is that some use different additives, not sure when this is added? at the refinery or at the fuelstation?
