Low Gas Mileage?

[Jimmy]

I drive a 94 3.4L V6 Camaro. I get worse gas mileage than my friends Z28 does. Off a fill i get about 200 miles. 200 miles per tank on a stick v6 is not too good. Even when i try and drive as lightly as possible it still just plain old sucks. Any ideas as to what may be wrong?

O2 sensors maybe? How long has it been since u changed those?

[Jimmy]

They were replaced within the last 5-10k miles if i can remember correctly. Actually... I think i only replaced 2. The ones in the engine (please correct me if that sounds stupid). If there are more than just 2 in the main part of the engine, then mabey i didnt replace them all. ??

Mine has had the same problem except that mine is an automatic. My mileage varies widely anywhere from 200-300 on a full tank.

i've been tracking my gas mileage for the past few weeks
w1: 17.235 MPG
w2: 23.001 MPG (went on a road trip, highway time)
w3: 17.356 MPG

sorry, but this SUCKS for a v6, that is why I am looking for an SS, better gas mileage, higher insurance, comes out to the same, so why not have a v8?

I will be changing my plugs, wires, and o2's, again, just to see if it helps.

I wouldn't jump to that conclusion. I just got back from a long trip where the speed limit was 55 most of the way and doing 60-65 I got almost 33 MPG with a 3.8 auto. But on my current tank, I am been going on short drives and around town and I am only going to get 17-20 MPG. It depends on how you drive really. When you wind out that little six banger to get some power out of it to pass, you are going to start losing 2-3 MPG. I don't know how you shift, but if you go out to 4 grand every time you shift, you are really going to kill your milage. Now, there is always the possibility of bad sensors. Mass air flow, Intake air temp (filter box), and one of the 3-4 O2 sensors in your exhaust tract. You could also have fouling injectors, plugged air filter, the list goes on and on. But what I listed is a really good place to start. If you can find someone with a scan tool to see if your computer has slowly been seeing differing numbers over time, that would be a good start. Really though, a lot of it all has to do with your right foot.

Oh, I forgot something, are you using your AC? If you are, that is where your gas milage went, with the hot air.

i get bad gas mileage in the city (usually 15), but that's because i'm not very easy on the gas peddle. on the highway i got 31mpg driving an average speed of 85 mph. Have you changed your air filter lately, maybe run some fuel injector cleaner through your system.

I have a 93 3.4L and I only get about 200 also. i aways have to hit up my mom for some money!

I got a 3.4 M5 and i get about a average of 275 or so per tank which is mostly city driving. [img]smile.gif[/img]

Check simple things and do a common tune up...it is always guaranteed to give a little better gas mileage.

replace your fuel filter
