i get between 100-120 miles on a half tank of gas which equals out to about 13.5 -- 16 mpg. and this don't seem right to me. especially since i got all new o2 sensors and a cold air intake. so my question is what are other users getting for fuel economy outta their 3.3L treps. thanks
on the OTIS I get 24.1 mpg that is mostly backroads and sitting in traffic but also some highway. I get more like 180-200 out of 1/2 tank.
omg! i dont get it! what i've got done that should help fuel econemy is :
fuel pressure regulator
o2 sensors (all 4)
cool air intake
i've cleaned the air intake
its got new plugs and wires
new coil pack (dunno if this helps mpg's but its new anyway)
camshaft & crankshaft positioning sensors
what am i missing? i could use the break with ALWAYS filling up!!! i even tried 89 octane and no difference!!!
With the price of gas we all may want to go to horse and buggy lol.
Grif maybe a tuneup and new air filter might help your mpg some, l use stp fuel injector cleaner in mine periodically also, which helps too.
tuneup what? i've done a full tuneup. are you talkin oil change and all that cuz i did that i just didn't write cuz i didnt think it'd help fuel ecomomy. and i got a brand new spectre air intake system (well its like 2 months old, but still kinda new) and i also have ran seafoam thru the gas tank as well. that should clean injectors right?
lt sounds like you have covered it pretty well, l'm not sure what else to tell you since l'm not a mechanc. Did it ever get good gas mileage before all this or has it been like this since you got it?
i bought the car in december, but didn't start driving it until january cuz i was in the bahamas. but it actually got WORSE gas mileage and the bit i've done has helped sum....not much....but sum.
darn it.....i wish there was just something i have been overlooking....
I only get about 13-14mpg in my 96 3.5 in city driving. On the highway, I do get at least 24mpg though. There's a big difference if you're doing lots of stop and go. I had my car all tuned up with new plugs, wires, and filters recently too. I'm very easy on my accelerators and brakes, driving in the city, my rpms never go past 2,000 rpms,so imagine if I drove it hard haha.
