i was surfing around the internet and found this adobe file with "tips" on increase your gas mileage. some of it i agree with, some i'm not too sure about.

what do you think.
personally, i get around or better than what the alero is rated for.
things i have done from the list include
NGK spark plugs, K&N intake, Seafoam regularly, Full synthetic oils, High tire PSI, aluminum rims.
now the synthetic oil, i never believed it to really make a fuel mileage difference.
My mileage is
City, 25-27mpg (this is usually hard driving, not driving like an old lady)
Highway, average 35mpg. but have gotten 42 on a few occasions.
what i average in the alero, 30-32mpg mixed with small town driving (lots of stop and go) and highway driving.
