Hello peep's.
I'm thinking of getting some of this stuff ^^^^^ where's the best place to buy it? or is there another type product to use?
I'm getting pretty poor mpg av 45mpg on a 301 mile trip

used half a tank of derv!! i was hoping for at least 50mpg

i know my car is heavier than a manual being an auto/tip, or am i expecting toooooooo much?

Cheers.
Dubbz.
