My cheverolet cavalier isnt getting good gas mileage.
 
I filled it up, 3 times...and its only getting 260-270 miles per tank. Isnt that a bit low?

Is it the 2.4 liter? If it is that's about right. The smaller 2.2 motors can get almost 40MPG but the 2.4 gets an average of 24-26

there is no way they get 40mpg. i fill my tank on friday, and by monday im already at half tank. i do drive a bit, but probably about 40-50 miles. i dont see how it can get 40mpg.

My grandfather has a 2002 with the 2.2 liter and he drives with a really light foot. He calculated about 37 or 38 MPG. like I said almost 40MPG. For those of us who drive real world speeds, you're right, yoou'll never see close to that. When I drive his car, I get around the high 20's at best.

If you're running it to empty, then yeah, that is pretty low (less than 20mpg).
 
I have a 98 LS sedan with the 2.4L engine, automatic. 22-27mpg is pretty typical, with a lot of short trips.

I have an 01 Z24 with that motor and I clocked about 24.6 MPG. The dealer said 40 for my car but I knew that would never happen. Those 2.4 engines aren't too fuel efficient for a small car. My old 1992 Cavalier with the 3.1 V6 got 30MPG.

have a 97 cav gets 40 on highway with new plugs ,ignition module,coil packs.wires and plugs..tune your car up and it will get factory specs,also use luckas fuel system treatmant with every tank,also I drive in town and will get about 29 to gal. there is a different with highway and city,in the city every time you are sitting still it uses more gas. I have never gone over 60mph, when you drive fast you loose gas mileage.. but I drive lite it's only a 2.2 liter.30 dollars to fill up and get about 425 miles with tank and I have 167,000 miles on it.

I have an 02 Cavalier. I can get 40 on the highway if I drive the right way.I don't do much highway driving;mostly 45mph zones with stop light. My last tank went 457miles for an average of 35.88 mpg. This is not on any long trips; longest drive maybe 20miles. I practice what's called "hypermiling" ( includes higher tjre pressure, swithching car off at long lights, etc) and also did some aero-dynamic modifications( nothing expensive, just soda bottle, aluminum cans and duck tape I have gotten over 500miles on a tank during the Summer. I used to be lucky to get 27mpg before.It may not be for everyone,but it's become a game for me.

What sort of modifications do you do with soda bottles, aluminum cans, and duct tape?
