i was just wondering how many miles you guys get on a full tank of gas. I have a 87 non turbo auto and i think i get pretty crappy miles. sometimes not even 200 miles to a full tank. Most of the time its around 180 miles to a full tank. can you guys tell me what you guys get. thanks..AND i use 76 gas with 91 octane

I was getting around 230 to 240 a tank with a 3.73 LSD Modified intake (cone filter with cover) headers.
I replaced the 02 sensor with a new denso I ordered from amazon for around 35 dollars or so, put a 3.91 LSD on the car and with AC I went up to around 290-300 and up to 330 without AC. My AC uses approx 10% more gas but I don't care!!!
Basically I went from around 16 to 19+ and a best of 23 mpg. I suggest replacing your O2 sensor at a minimum, check tire pressure, air filter, oil and a tune up. Also check which diff your running. A ratio like 3.73 is too tall for our NA powerband so I actually got worse mileage and my 0-60 was way less.
I can't find a 4.30 LSD here otherwise Id slap it on and see the mileage results from that and times.
I still need a new set of plug wires to go with my iridiums that Ive used for over a year.

It depends on the type of driving that you do.... For example, on the highway, I get between 350 and 375 per tank, and city driving, I get about 100 miles less (250 to 275)

Basically I get about 19 to 20 mpg city driving and about 26 to 28 mpg on the highway.

Oh BTW, I am also running 3.73 rear

LOL! u guys get gas taxes HA HA HA /\/\/\

I get about 20 city and 25+ highway

mods, Replacement K/N air filter and a shimmed waste gate.

FYI put your O2 sensor in paint thinner and see if that fixes it before buying one.

I got an 88 NA. Not exactly sure which diff. yet tho but Id be willing to swap it for another just to get better gas mileage. Right now I get like 19mpg average and thats with a lot more city driving than freeway. I still have a lot of tuning up to do also. One of my goals with this car is to make it as efficient as possible.

I get around 21 to 22 highway, and much lower in town. I do drive a little hard, though....

Edit: CAI, OBX header, full exhaust and test pipe, clutch, DSS steel drive shaft, I have a serious lead foot as well, and would probably get much better mileage if I backed off it a bit.
