I went to a show in AL the other weekend. Well because of some work we did on the car I had noted the mileage before we left. Now we knew the balancer is all wack. Got a new one now, just have to get the others cars going so we can install it. Well anyway I filled the car all the way and the mileage was reading was 012. Now we go to AL and come back. I'm running 70-75 with the group the whole way thre and back. I stop to get gas before I get home. Mileage 326...filled it all the way it took 12.5 gals. So I went about 314-315 miles on 12.5 gals. I did the math and the car got 25mpg. Wow it has never gotten that good of mileage.

What do you guys typically get on hwy driving? I used to get 17 or less before the work we did. That and & realizing the balancer was off, we increased the timing. Balancer says i'm running 20 degrees. Oh I can't wait to get the new one on!

I posted below, I had to go out of town on last minitue notice, got between 24 and 28 highway, 65-80 mph. Intown, below freezing weather, 17.5.

Topic I stated that on, https://www.thirdgen.org/techbb2/sho...hreadid=141741

I get like 2 mpg...

Or, is that ? Oh well.

jesse23

mmm i filled my tank and i get like 150 or so on a FULL tank
Something wrong with my car?

3.1 RS 91....

A '92 3.1l would get ~ 26.5 MPG at a steady 75 MPH. That is what the factory EPA(?) sticker rating is too.

So you did good at 25 MPG redraif.

RBob.

jesse23

what about mine
why am i getting like 12

Doward

22mpg, in city, hiway @ about 90mph

Jesse, when was last time you did a tune up??
What mods do you have?
Chang O2 sensor, might have dirty injectors, timing wrong, EGR valve going bad, Dirty air cleaner, bad alignment, under inflated tires, Many a things can cause bad mpg.

TomP

I've got a leaking injector and a heavy foot... those are my problems! That and the fact that all my driving is in traffic... I haven't seen a highway in a while... (sigh)

I got 17 MPG city, below freezing weather, and thats with racing 3 times.

Keoki_Firebird89

back with the 2.8l i pulled off 21 MPG in the city, with the occasional peddling and racing... sigh... miss those days.

with the 3.4 i waste more gas. but ever since i put in my new intake i've been doing better

2.8L on a full pulled off estimate 260-270 miles
my 3.4 i think pulls off a 230-240 maybe better
i don't know yet.

and i still plan on getting MSD equipment and headers.

Keoki_Firebird89

oh and all my driving is city driving, plus my foot is pretty heavy... so i'm sure those numbers could be even better.

jesse23

only mods are what i did today the custom CAI

tune-up no idea, need to do TOM's major one soon though

Dale

that would be why then.


GO DO A TUNE UP!!:sillylol:

jesse23

if not that what else could it be?

mike1986fyrbird

a tune up :P

mike1986fyrbird

or a 02 sensor. all i can think of right now

jesse23

i knew i had a problem cause earlier my friends brother asked to hear my car. So I revved it and he said wait do that again. He then pointed out how my exhaust pops and said something about a smell. He said the smell was my car running too rich of a fuel mixture. So my guess is o2 sensor. How hard is a o2 sensor too replace and whats it normally run?

SSC

Redraif, Wow never looked at your pics before:hail:. Damn you did alot of freaking work to that car!

Oh, 17mpg city, 20 highway. Who says a V8 cant get as good as gas milage as a V6.

SSC

Usually around $35-45, It takes about 15 minutes or so. I dont think a faulty o2 sensor would cause it to run that rich, Id lean more toward faulty plugs/wires but an o2 sensor wont hurt especially if it hasent been changed in 12+ years.

I normally get 23 city 25-28 highway, but down here in Southern Illinois, there are so many hills and bumps and such that I can literally coast half a mile without touching the pedal. I just let momentum carry me forward. Of course I can only achieve a long coast at 40 mph. I bet I am the only one here who drives 40mph on a country road. Anyways, my point of the coasting is that it can add as much as 5-7 mpg to the city/hiway milage. My car has had 5 tuneups and 4 oil changes in the past 3 months. I had a lot of repairs in that time frame.

I was getting 12 about a week before she died, and a while before that it was like 20mpg, but now it gets 0mpg

redraif

Cool. I had always wondered about the infamous great gas milege these car supposedly got. Now I finally get it. Before this best I ever got was 15-17 on the hwy. heck the sticker on mine says 17 city and 21 hwy. So I guess the 2.8s were not as good as the 3.1s.

redraif, have you got that new balancer on yet?? And where did you get it from for a good price? I think mine has spun on my s10.

Its not on yet...too many other projects going on, plus both of us being sick and then a death in my family last week. She got it from NAPA, it was $43.
