How do you increase your MPG on your car?

I got 60mpg in my Honda Civic recently for 100 miles by coasting downhill and increasing air in tires by 5psi.

How do you do it?

Hypermiling - Look it up.

It is DANGEROUS to coast downhill and airing up your tires over the recommended pressure. A tire blow out will wipe out all your savings. Buy a Prius if you want fuel economy.

Keep the engine tuned
keep the proper psi in the tires
remove anything inside not needed
drive @ 55 on freeways
be sure all fluids are at proper level
on surface streets, look way ahead at the 2nd or 3rd traffic signal and time your driving to avoid stopping

All cars coast down a hill and 5 lbs extra air isn't going to give you 60 mpg…

If I want fuel economy and remain relatively safe on the roads, I plant the vehicle in the slow lane and set the cruise at the speed limit.

If I want to spend the least amount of money on fuel as possible ( and not rely on public transit ), I park my car and take my motorcycle for longer trips while walking or bicycling for shorter trips.

I don't worry about such palrty short term stuff.

It's illegal to coast your vehicle. You do not have full control of your vehicle.

By driving a Prius. I never give gas prices much thought.

Take the coast road. The long way around rather than over the mountains. Drive below 45mph. In speed. On the paved road. Buy a vehicle with no power accessories. Like power steering or brakes. Roll up windows. I do have A.C. In mine. They eat gas. Turn it off when cooler outside. Drive a 3 popper motor. I have the big 3 in mine. Do not buy a car with pollution controls on it. Just plain muffler. Avoid using 4 wheel drive were possible. Use low octain fuel. Fuel injection on a vehicle is I'm told a help. Avoid in town driving. Stop go stop go. Shut of motor at oxen crossings & such were you will need wait for them to cross. Or were wrecks are.
