I ride my bike alot in the summer..helps alot on gas.
Even simple things lke getting all that crap out of your trunk helps out with reducing weight and gas consumption.
Also, be sure that you car is running properly. If the car is running rich youll get lowr gas mileage. Also I imagine that having gunk in the motor hurts gas mileage as well. Try running seafoam through the car, it may help.
Also, if you screw a large block of wood under the gas pedal, you wont be able to mash down on it
Ultimate gas saver
Also seems the fwd models get better mileage....possibly because of weight and less driveline strain. Curious if running the car w/ the fwd fuse in would help gas mileage (Id test but my car is already fwd)
