Whats your MPG?

Have an 89 YJ with a 4.2l that is my daily driver. My wife just found out I only get about 13mpg and wants me to sell it. I was just wondering if this close to what others are getting? I took the doors off but it didn't help much. May need to trade her in for a new one (if she keeps complaining :-).

Not sure if it will help, but my 95 2.5l I4 gets around 17-18hwy, and around 14 running moderate+ trails on the weekends. Worst I've had was around 12, but that tank had 20-40miles of rough off road, and a long steep rocky uphill crawl section....in the rain. Used 4lo a lot that day lol.

I get around 16-17 in my 88 with the 4.2 with no lift and 29" tires. What kind of tire setup do you have?

I have a 4.0 also and am running 33x12.50's with 4.56 gearing. With that being said I get about 14 mpg all the time. I have got up to about 18 at times but that is on road trips in perfect conditions. I also always keep it under 60mph since half the fun of a jeep is enjoying the ride.

Getting 15mpg average. From what I have read with carbed engines that about average. Those that have fuel injection get 17-19 average. Yes that all depends upon tires.

I am running 33x12.5x15, I would guess stock gears, no cat and a Weber carb with almost no vacuum lines or anything else hooked up. Sounds like I am doing ok (until emissions inspection next year.) Thanks for all the response!

95 4.0 average 18mpg with bikini, 19mpg with bikini and soft uppers doors.
Thats at 60 on the highway, it seems little less at 55mph. So I tell my wife after math that's around 21mpg, factoring in tire size. Right or wrong sounds good. I have 30X9.5 tires and speedo is set for stock tires.

1994 Jeep Wrangler, 2.5L with manual trans, 31" Toyo AT's, 4.10 gears, Rugged Ridge air intake. I seem to get 17.1 to 17.3 miles to the gallon driving around town, and that is with holding on to the gears a little longer than I probably should just to get moving down the road. I add 6oz. of Marvel Mystery Oil to each tank full tank of fuel. I lose about 1 mile to the gallon with a trip to Silver Lake, averaging 60-65 mph, which is about a 70 mile round trip on the highway.
