Miles per gallon?

Jump This · Jul 16, 2003

What kinda milage are you all getting with your various rigs? That is to say Running 35's with 4:10 or 4:56 gears etc.
Currently I am running 32's with the stock R&P and getting about 14mpg........

sometimes 16mpg.

My last tank was 16mpg. Which has been the best yet. Usually I get 14-15 or so. I have 33s 4.10s and an auto. I think my mileage will increase when I regear.

MPG

I was averaging 20.5 mpg STOCK (AW4, 242, 3.55 gears, 225 x 70 x 16 tires) I installed 30" tall tires and dropped down to 18 mpg.
I'm going to re-gear (eventually) and I'm tossing around the idea of a 4.10 OR 3.73..... 3.73 brings me back to the same RPM'S that I had stock. A 4.10 is 2 axle sizes up. I would go with 3.90's but they don't offer them in Dana 35's.
I certainly don't want to drop down to 14/15mpg, since this is my daily driver (60+ miles round trip to work)

Anybody else running 3.73 or 4.10's with 30" tall tires? What are you getting for MPG?
BTW....I checked my speedo for error after I installed my 30" tires, my old OEM Goodyears were 28.25" tall. I checked speed on GPS......IT WAS RIGHT ON THE MONEY!!!

Do you think that if I went to 3.73's, I'd get most of my milage back?

18 mpg with 30 x 9.50 procomp muds, stock motor, 3:55's, AW4 on the freeway & city streets (50/50 mix). 20 mpg on 75+ mph freeway runs.

I get 13-14 in my '91 auto 32's & 3.55's and then 20-22 in my '95 5-speed 3.07 225/75-15. Remember that if your speedo is off from regearing or larger tires, your mpg is also off by the same %.

Tom R. · Jul 16, 2003

When I owned an '89, 5-speed, 235x75x15 tires I averaged about 20-21 MPG combined driving. I got about 25 on highway trips.

My '92 with 32x11.50x15 tires, auto, stock gears gets about 12-13 in winter and 15-16 MPG in summer.

I gave up a while ago...... with my 98 ax15 with 4.11's and 31's I get about 15 to 19 depending on the phase of the moon, the quality of the gas (seems that quality goes down when price comes down) and how long has it been since I dumped the container of the injector cleaner into the tank..

Now I drive about 120 miles round trip each day in the morning flying at about 80 in the afternoon... well... let's just say that I drive all across Los Angeles down 5 south....

Oh... it seems that my cone filter has improved mileage a bit for me as well as the bosch 4+ plugs..... (alkthough it is a possibility that it was the fact that they were new, but... the ones that I pulled out didn't look too bad...)

I get 15-16 around town and about 18-19 on the highway. I have 3.07's with 31's. I also have the TB spacer and I noticed a slight improvement in power and mileage after putting it on.

CameronB · Jul 16, 2003

Apx 14-18. My speedo and tach is off due to 31s, so I est it a little. I do monitor each tank though.

This is a 95 w/Rusty's TB spacer, intake, and cat back. MSD coil and Magnacore wires. I can't say that any of these helped milage noticably. What did help recently was adding an oil 'stabilizer' or additive from Napa called 'Lucas." Quicker starts and more mpg.

Hey Bluto, if your speedo was off before w/ smaller tires, and now is right on, than doesn't that mean your perceived mpgs were skewed to start with?

Matt99XJ · Jul 16, 2003

I get 15.7 around town with 33's and 4.56's.

MudDawg · Jul 16, 2003

15-16 mpg with 33's and 4.88's....of note...when I lifted it and installed the tires with the stock 3.73's the milage fell to less than 10...after the regear, back to normal...

Now that the gauge is working right again. On the highway with 4.11 gears/AW4/33x10.5 BFG AT's I am getting between 18.8-20mpg. I do have bored throttle body, K&N, Tornado, Snorkle, Borla Exhaust and high flow cat. These all can help the mpg if you don't have a heavy foot. Juice

13 in the mountains where i live. 16 or so at 3,000 rpm on long road trips, back when the speedo was actually working.

212,000 mile Renix 4.0, NV 4500, 35's, 4.88's, 4,500 pound rig.
