change your air filter

Gas mileage is a matter of the engine's ability to covert Gasoline in to power. If all the settings are not correct, the engine will not develop the normal horsepower and you will have lower mileage.

You need to check the compression to make sure that the valves and or the cylinders are up to specifications.

You must make sure that the ignition timing is according to specs and depending upon how old the car is and what service is has had, your timing chain may be worn to the point where the valve timing is not correct

Start with the ignition timing. If resetting it does not improve your mileage go for the rest of it.

Hope this helps

I just went through this problem and here are the answers I got from
mechanics (over the phone) and the people around me...
air filter (about 20 dollars canadian, easy to change the mechanic would have done it for free)
spark plugs (anywhere from 3-12 dollars each, I have 6 in my van. Harder to change, depending on vehicle, they would have charged me 100 dollars approx.)
computer chip, I don't remember exactly what he meant but something to do with a sensor(sorry, he didn't tell me how much, but he would have run a diagnostic for 35 dollars)
We started out with the air filter and... huge change! Cut the gas in half(again, our problem was severe, our van was using twice the gas it should before we changed the air filter)
I hope this helps!

It's the methanol mixed with the gasoline.

It flows better than gas, so cars with carburetors don't have all the computer controlled fuel management to cut the amount injected into the engine.

Our cars were designed for gasoline the way it was blended 40 years ago with tetra-ethyl lead that actually congealed when it hit the air. Gas now leaks from every crack.

I'm going to try jetting my carb leaner (one of these days when I get around to it) and see if it runs ok.

All "old" cars depending on the year were most likely high compression engines. A number of things can happen to lose mileage
1. air filter clogged increasing gas consumption
2. low tire pressure increasing rolling resistance
3. poor quality fuel i.e. ethanol, mtbe, hexane
4. spark plugs fouled causing misfiring
5. spark cables worn causing misfiring
6. distributor cap/rotor worn causing misfiring
7. points and condenser worn causing misfiring
8. camshaft worn causing fuel waste
9. valves worn causing fuel waste
10 cylinders worn causing loss of compression/ fuel waste
11. wheel bearings worn causing increased rolling resistance
12 Automatic transmission slipping bands
13 clutch plate worn
This list can go on forever...

Buy a used import, i.e. Toyota Echo 41mpg Hwy.

Quit spending all your money on computer games, CDs and other crap and take your car for a tune up.

Change the oil, fill the tires, clean the carb, change the plugs, etc. If you want the car to take care of you, you need to take care of IT!

try changing your spark plugs. you may have a foul plug and this could cause your gas mileage to be poor
