my first fuel mileage check

[nebrfestiva]

I'm sure it can get better, but the first mileage check was 32mpg. I changed plugs, cap, wires, coil and rotor yesterday so I hope it improves a little more after the tune up. Now just the wait for Summit to deliver my new intermediate pipe and muffler.

check the timing and tire pressure!

Also check your tire size. Stock sizing was 145/80-12 or 165/70-12, which are about the same diameter. If you're running 155/80-12s then you need to add a bit to your mileage since they will turn fewer rotations for the same distance, indicating you haven't gone quite as far.

On the other hand, folks report that stock sizes do not match what they get on their GPSs and that the 155/80-12s are actually a bit closer to real speed driven.

Best thing to do is to get your own GPS and check your real speed and distances to get a more accurate reading.

Alignment, and the temp sensor on the intake manifold (thanks htchbk) can also hurt your mpg.

Oxygen Sensor and thermostat (how's your heater?) can effect it as well.

in town or combined? 5 speed would help on hwy!

Corn free fuel helps number crunching..

He may not have that option!
Here on the east coast, non-contaminated gasoline is hard to come by!

[Movin]

Thats bad!! what do the 2 stroke crowds use..outboard engines, snowmobiles..?
Or do you have to have that engine there to fill it?

[Pu241]

Think you can still get real gas at marina's, but I haven't tried that route yet.
Likely boat fuel doesn't have road tax on it so, they wont let you fill the car up directly.
My dad has a '54 Hudson that he has finally come to understand that it doesn't like ethanol contaminated fuel. So 5 gallons at a time he get fuel from the marina. Fortunately, for everyone, my dad doesn't drive very much!

Ethanol contaminated !! I like that!

Ethanol contaminated !! I like that!

Or my favorite term for 10% ethanol gasoline, crapoline!

[Movin]

heh heh they should add the sales pitch " possesses exceptional ability
to collect 2 atoms of hydrogen and one of oxygen from the atmosphere!"

since I have moved here to Raleigh I have been able to find non-crapoline. I think that VA crapoline was what messed up my last carb. When I rebuilt it you could see the deposits and where it had damaged the accelerator pump diaphragm, not to mention gaskets and such.

I dont know much about good gas mileage.......My average is lower than I would hope :p
