My car is now a chip van.

[4WayDiablo]

Mine smokes a lot more both on and off boost when running pure veg.

Also notice it doesn't pull as well after 4k.

Guess that's part of the deal when your saving 50p a litre.

Mine actually smokes less on 100 pure veg :-s
But yeah ive always noticed the peformance difference but like you say 99ppl is a lot better than 1.50 at the pumps
