What Diesel?

[BruceT]

Does anyone here know if the HDi90 benefits from the 'v-power diesel' or 'ultimate' diesels?

I know performance Turbo's, especially tuned ones benefits from the higher RON rating but what about diesels?

Is it ok to chuck in Tesco diesel or do these prefere Shell/Esso/BP fuels and are the 'super' diesels worth it on the HDi?

I once chucked in some super duper diesel by mistake. It did seem a little better out on the open road and needed less extra throttle to keep speed up hills and what not but the main advantage i found was that my car started a tiny bit quicker and that it smoked a lot less when it was cold or under hard acceleration at low engine speeds.

As a means to gain extra performance out of them, well, it does seem to make a tiny bit of difference BUT... i could of just been looking for that so could have been imagining it. But it certainly cut down smoke levels a little

I tried it in my HDi 110. It makes very little difference to performance and mpg.

The call it Eurodiesel here, the 2.1 runs much smoother and definitely pulls better on it but like GeordieBoy it makes burger all difference to my HDi

B30 FTW ^^

I tried V power a few times in my 110 and noticed it would be a touch quieter and maybe a little perkier on the throttle but there was now 'wow' at all

Expensive stuff too.

OK.

Think i'll keep chucking in Tesco Diesel then, handy with clubcard and 5p off

I have been using Tescos 99 ron petrol recently and have started 'paying at the pump' which is a bit weird but works well I have found. It is weird entering your PIN number before you've bought anything though

I haven't noticed any difference on my 2.1

I know it's petrol and we're on about diesel here, but 5th gear did an interesting test the other week comparing supermarket crap with ultimate and v-power in 3 cars on a rolling road. Turned out to have no effect on a basic <90bhp 1.8 engine, something like 10bhp extra in a 150bhp car and about 25bhp in an impreza sti v-power came out on top, but bp ultimate wasn't far off the pace

Mirrors what I've been saying - ultimate produced better economy in my 150bhp tubby, but not enough to be worth the money, but my V6s have been much better on the stuff, and v-power got me 707 miles to a tank!
