Bad Gas Mileage

[moldyoldy2fody]

My 1991 240sx coupe 2.4 twin cam is getting around 25 mpg under normal driving conditions,what is the average mpg for this vehicle supposed to be? I have removed alot of emissions equipment such as charcoal canister and egr,with all equipment associated with it.

That's pretty good for around town driving. I get about that much in mixed driving, with lots of highway speeds and laying on the throttle whenever I can.

you think your getting low miles??? mines bone stock. i checked today, i get ****** 16 MPG. that doesnt seem right at all

Changing your air filter, oil filter, oil, spark plugs and wires will most likely set it to its normal standards. Tire pressure too. I havent checked how many mpg i get but then again I havent filled my tank to full in almost a month lol.

I agree, that sounds like it needs a tune up.

Does the car feel like it has no power?

Also, at what rpm is it idleing?

I have heard that a bad O2 Sensor can affect gas miliage also is that true?

[TrueVillan]

Yep, get yourself a nice tune up and see what happens.

to the op your car sounds like its getting good mileage man, 25mpg assuming thats in city is damn good for our cars considering the age.

i can burn a quarter tank in about 2hours worthing of city driving .. its about 4 gallons

actually sounds about right, you gotta remember that a 2.4 is a rather large 4 cyl.
