Miles per Tank on 4.0L?
 
Just curious this. I see what people say for MPG's but most of them are 4 cylinders. What about the 6 cylinders. I know mine is not good on fuel being my gauge does not work, until I get this aftermarket one all wired up. Last time I ran out of fuel on the road I had like 180 miles to the tank that was full. I did some offroading and lots of idleing and testing but is that normal? With normal daily driving is that all im getting? Givin I know my tires are not helping ONE bit.

Setup:
91 4.0L Auto (bummer but I may swap in an AX-15 soon)
15x10 Micky T's w/ 31x11.5x15 TSL Swampers

I never run to empty-but the idiot light and chime usually happen around 240-250

jrussblues 04-17-2011 07:05 PM

lol average 115 miles to a tank. Little better with a tail wind. Farthest ive ever gotten on a tank was 131 miles. Which is a whopping 8.7 miles to the gallon.

All of you who averaged like 230-240ish, how big of a tank do u have??

kj 92yj 04-18-2011 07:33 AM

15 miles a gallon x 20 gallon tank = 300 miles for me..........but i always chicken out and fill it between 260 and 270.

BPJOOP93 04-18-2011 08:08 AM

130miles. roughly. 33x12.50 stock3.07 gears all city driving.

Abomination93 04-18-2011 01:01 PM

Well I get between 15 to 17mpg x 20g tank = 300-340...but I dare not touch 250 w/o filling up...I hate running out of gas.

4.0l ax15 3.07 gears stock tires or 33x12.5x15.

My jeep is consistant for mileage, it is mostly highway driving I do.

I think the manual says 19 gal. I have 31s 5spd and 3.73s almost exactly 50/50 driving city/highway.

mysic93 04-19-2011 09:01 AM

Your not alone,Our 93 YJ barely gets 15mpg thats on the street or in the hills.6.0-5spd.4"lift running 32s.:banghead:

Moroney167 04-19-2011 10:47 PM

Awesome thanks ya'll makes me feel good about runnin out at 180 but that was pretty much all idling, testing, and trails. With the damn swampers on.

Installing a Sunpro fuel guage this week so no more guessing! Thanks for the info all.

Moroney167 05-01-2011 05:45 PM

So bump for this. 180 is deff all I can get ran out the 2nd time now at 175 haha. OOPPPSS. Might look into a small sneekie peet fuel container somewhere underbody or use the ol military can setup off r. bumber haha. Wish I didn't have these damn TSL Swampers I do a lot more road driving thatn I expected!

perkalator 05-01-2011 05:49 PM

I get about 240 miles average per 20 gallon tank on 33 12.50 and 3:73 gears. Don't trust your odometer unless you have corrected for oversized tires.

EmptyPockets 05-01-2011 06:44 PM

330miles to the tank. I have 3.55 gears.. don't know if thats stock or not. I did a test to see how far off my odometer was.. found out it is .2 miles off. I have some math to do to find out what my mileage is... 16.5mpg... was more but got a lift...

rivera82 05-02-2011 09:28 AM

4.0, manual, 35" tires, 4.10 gears (switching to 4.88 soon) I get 15.8
