Re: Gas mileage question
Try running half a tank of 89 or 91 octane gas and see if that improves mileage any. Be sure that you have no fluid leaks of any kind. Whenyou say you changed all the fluids did you also change out the differential oil and inspect the gears? You might want to change the spark plugs again since you ran the plugs on the old unstable fuel. Fill up, run it for a good five minutes and then change out the plugs and see if that makes a difference. Old/bad /dirty fuel can foul plugs!
