Gas Mileage

[Smokeyone22]

I have a 01 V6 Solara with 51,000 miles on it. I was gettin about 24-25 MPG round town and 31-32 highway but now it all of a sudden dropped to 16-17 around town and 25 highway any guesses?? Thanks

Have you done your basic maintenance?

Check the air filter - change to a clean one?
Check the tire pressures to see if they dropped? Low tire pressures (below recommended) = less mileage
Check the plugs to see if they are fouled? or have bad electrodes?
Change the fuel filter?
Possibly add weight to the vehicle ie: stereo system?
add any performance mods that could reduce mileage?

Other than excessive weight, none of these will apply as a 'sudden change'. If the plugs are fouled, he should be able to notice that he's running on 5 cylinders or less.

It could be just as broad, but there are much simpler solutions like not using your defroster, rev below 3k in the first 3 gears, or find a different gas station.

Really? I have had bad plugs give me poor gas mileage and yet show no signs of misfire.

Mine has started doing the same thing lately. I'm thinking it may be the winter gas?

Your initial fuel numbers are very parallel to my '00 SE-V6 5-speed manual shift DWP.......25-27 and 31-33 HWY. You are due for plugs at 60k; my cost for this was $197 which included air/oil filters. So for less than 200 clams - provided you are a 'smart shopper' you can return (hopefully) to the society of fuel efficient forkers....................ez

i put new plugs in and a K+N air filter in. there is no excessive weight, i have no stereo i may try a new fuel filter. How easy it is to get to and where is it on the car?? thanks guys!

[Smokeyone22]

i will also try a different gas station. I have been getting Hess maybe i will try mobil thanks for the help let me know about the fuel filter location and if it is easy to get to

I am experiencing the exact same thing. Did everything on that list, and my gas milage has gone to crap. Im a 99SLEV6 w/ 82k miles.

it could be the way you drive.

[Smokeyone22]

i drive conservatively and dont get on it. I put a new fuel filter in the car today and also tried some of that Z-max stuff i figured what the heck and it was onsale at advanced auto. I will let you know how everything works out

[Mole]

have you had your Defroster on a lot?

[toy4x4boy]

So you're saying he was driving conservative and now driving like a maniac? Doesn't make sense.

I drive mostly conservatively and my gas mileage has gone to hell recently. I think it's just the winter gas.

Its not just that its old oil and/or gas.
I'm not sure where he is located but most winter gas is of a different blend, i think its more oxygenated.

Also when i use my remote start a lot, my gas mileage gets crappy
