not available up north yet or if it is I havent seen any, I've tried BP's equivalent brew, not impressed really, eggbert felt better on shells normal diesel which is what I always use.
By the way I have also tried the Millers fuel additive, the car seemed smoother but there was no perceptable gain in mpg as promised, possibly because I always use a quality fuel, if you use supermarket fuel that doesn't have all the fancy additived than maybe worthwhile.
