that sounds almost rational.. except for the fact that gas freezes (depending on type) between -120F and -240F.

and that kinda cold doesn't exist outside of a lab.

its all the enviroment your car runs in, that changes your mpg.


in the cold, people drive slower, idle longer, get less traction, have colder air, have more components running (defosters and such) all adds up, when you calculate this kinda stuff. typically we weigh more too.

That better not be a power wire going into the fender!!

yeah, oil, injector cleaner, air filter, plugs, fuel filter (maybe?), and go from there... also make sure your tires are properly inflated.

This is a very active forum, which is nice considering I'm a "newb" to owning and caring for/modding an Alero.

and on the power wire there is a grommet in the firewall to run your power wire through not the fender...

I know this is a later post but I did not want to create a new one for the same subject. I have been tallying my mileage after the new exhaust and I have found that with my v6 3400 with a CAI, high flow cat and pacesetter exhaust I am able to reach 28-29 mpg with a MIX of city and highway driving. My driving style is more reserved but with the new exhaust I do flex Angel a little bit more to enjoy the sound. The mileage is even better with the increased aggression. Just wanted to pass it on.

Just because it says "max capacity 45" on the tire does not at all mean that's how much you put it. If you look at the manufacturer's suggested pressure (usually a sticker on the inside of the driver's door (unless you have a German car), it says anywhere between 28 and 35 cold. Already putting 35 cold is too much. For best MPG keep it at 32lbs.

i never had a problem running my tires at 44psi. my old car i had them almost up to 50psi. but those were 10ply truck tires on it.

and the manufactures sticker works great for tires that came with the car. but different tires run different psi's.

but i can see what your saying. so people should keep them down.

i recently purchased some good year fuel max tires. And a set of e3 spark plugs. and just installed my wai. i'm hoping for some better mpgs!

The factory inflation pressure is for a mix of comfort, handling and economy.

I myself run about 41 in the front, or else I tend to wear the outside edges a bit faster.
