Folks,
If supermarket diesel is watered down with non-diesel stuff to make it cheaper / cleaner / less "go" (queue someone with a scientific term), is the same done with petrol?
I filled up my rocket with expensive Shell petrol and have just finished a tank of "normal" petrol and have actually got higher mileage out of the normal tank. With the 120, I get more miles per tank with the expensive diesel than with Tesco's finest. Might be placebo?
