Just put around 800 miles on my '88. Ran the injector cleaner through it. Seems like I'm using alot of gas. Course I never shift below 3000 rpms.
I just filled up so I'll check my mileage at the next fill up. I saw a thread about an o2 sensor. Are they easy to replace? Where to buy Advance auto or Auto Zone? Is the o2 sensor maybe bad?
Thanks!

I see up to 25 mpg on the highway at 80 mph, sometimes it seems like I'm getting more if I cruise in fifth at closwer to 55 or 60.

When I'm putzing around town it's usually closer to 16, sometimes worse depending on how itchy my right foot is.

wow, I don't get near 25 on mine in highway, I think my alltime record was right at 20mpg. Around town It's freakin horrible. course mine is a modded turbo

STOP POSTING MILEAGES LIKE 20MPG AND 25MPG


...that way my pathetic 9-10mpg seems horribly inadequate (and also suggesting that something's wrong )

something really horrible, different injectors and different fuel pump...

88 Vert N/A, Full tank 235 miles later now empty, and I tried this tank like grandma!!!!!!! I get about 200 if I drive like crazy... Not much difference huh?
By the way Mykl I think you stole my car!

I get about 375-400 miles from completely full to the low fuel light normally. Thats about 24-25 mpg. If my right foot gets to bored, I get about 20 mpg. BTW, thats mixed city/highway, but mostly highway.

i got 450 miles on my last full tank in my n/a...cruising around 85-90 for 6.5 hours from NJ to VA...that was probably the best i ever got

the T2 eats a little bit more gas, but not too much...

My TII gets like 150 miles per tank... goddamn Walboro pump.....

Yo,

4.3 gears are nothing...Im getting 4.778 for my FC. Im sick of my way too tall gearing. I have smaller than stock tires, and i still am going 73 MPH at the top of 2nd. Top of 3rd is about 108.

Hey.. 4.3 gears and 108 at top of third. I have 4.1 and only do 100 at top of third IN my GXL... What do u shift at. 8800 rpm or something

mazdaspeed7

I have stock 4.1's, and smaller than stock tires(diamter at least). I shift at 8600....good guess, it was pretty close.

ajsuper7

24 was my best on the highway and that was when my car was packed with stuff for college ie computer, tv, clothes. id say 300 lbs worth of extra stuff besides me. so i think with less crap i could do better. in the city i used to get 200 miles to a tank but got injectors cleaned and 6ports uncloged and i put on an msd ignition...which helped alot i think so now i get 280 to 300 in the city

My 89 T-II I currently average 13-15mpg but I suspect leaking injectors...

The 87 T-II gets around 18-20mpg much better than the 89... Though the 87 is running stock fuel setup.

My 97 240SX SE gets 23-27mpg
