Best Answer

I've had a 2000 Alero for 4 years. I didn't expect great gas mileage, but there are many times I get under 20 mpg. There are also times when I'm able to get 35+ mpg. The gas mileage depends on the way I drive. If I keep my foot out of the gas, I can get in the mid to upper 20's in town.

AnswerYou can buy a tornado from like JcWhitney's. I have one installed and got better gas mileage and more horsepower.

Answer

Change oil regularly, change air filter, spark plugs, the O2 sensor is a big one (they call it the spark plug that never gets changed), cheap gas isn't always the best answer try mid grade instead, fuel injectors are also a biggie but some lucas injector cleaner will usually keep them in good shape. other than that watch how you drive.

Is Oldsmobile alero v6 better than Pontiac grand am gt?

To me it is for a few reasons, 1 is yyou are paying more money for the GT meanwhile the reg. grad am was alot cheaper than the alero, all the gt has more that the alero is Ram Air and all that is is the car sucks the air in faster so you get about 2 hp more. however the alero is better built due to the fact that it is an Oldsmobile and because it is from the Cadialic Family so it is good quaility parts, also the alero is a cross bettween a sports car and a luxuary car just by looking at it
