Ok so I would just like to know if there are any cheap or simple improvements that can be made to my car (1984 GL Wagon 1.8L) to increase the MPG. I have already discovered that keeping my tires inflated can improve my mileage by a good 1-2 MPG, but would like to know if there was anything else I can do to improve it. Along with that, are there any improvements that can be made to better the get-up-and-go power of my engine? I know these are kinda to different things but instead of creating two different topics I figured I would just kill two birds with one stone and ask in just one thread. Any suggestions?
