Gas weighs about 8.5lbs a gallon. If u always drive with 1 gallon in the tank that's a 161lb savings. That's your best bet
This seems like some of the best advice, but I think I can do one better. How about removing the engine entirely and fitting the car with bicycle pedals and just pedaling the car wherever I need to go?
Also, what about taking a prescription laxative concoction an hour or so before driving so that I can literally blow out any excess weight before I even step into the car?
