Ive been trying different ways to increase gas mileage and this is what I came up with. I hardly ever slam the gas at take off but I occasionally get the rpms up there. So I started shifting about 2750rpms for about 3 tankfulls and achieved 25mpg with 50/50 city and highway. When I stayed on the gas shifting at 3500-4000rpms I achieved lconsiderably lower...avaraging about 22 mpg. Does this make sense???? Ive been talking to a few other people on other forums I visit and they are telling me that I must not be staying on the turbo, which I believe kicks in at 2500rpms. So is it true that the longer you are on the turbo the more your mileage will suffer?
