I have been getting good gas mileage too, last 2 tanks it was 20 mpg, it is usually around 16 mpg. Could be the warmer weather maybe?

they probably just switched over to summer fuel where you live. summer fuel=less additives= more mpg

... when filling the tank, divide the number of miles driven by the number of gallons put in?

I got 24mpg my last tank, mostly highway with a few around-town trips. I'm still working on dialing my SAFC in for best economy, and I still need to get a set of cleaned injectors to swap in. Looking at a CD ignition system as well.

I normally get about 16... but I'm showing a few signs of REALLY needing some cleaned injectors.

damn just rub in it in. would having the injectors sent off for cleaning help with the mpg. ive replaced both fuel filters, o2 sensor, air filter. oh and thats 18mpg with me being a having a heavy foot driver around the city not much highway driving for my car.
