That's good. Yeah jeeps are notorious for leaky valve covers. Mine leaks also. My jeep also idles low every now and then

Did more math, last tank I was getting 20mpg average. 100 miles on 5 gallons of gas.

(well it's more like 98.9 miles on ~5 gallons)

That's really good mpg for a 2.5L! They are typically horrible due to the fact that you have to 'pedal to the metal' wherever you go.

I consistently get 18-20. With the top on I can easily hit 80 on the interstate as well. With the bikini top acting like a parachute I get 14-15 at hwy speed.

32" M/T tires, no regearing 20 mpg all day long ,e-fan ,and accel ignition and e-3 plugs have all contributed .I do not drive light footed by any means .Keeping fresh quality lube in the axels and tranny /t-case will also help no matter what engine you are running.20 mpg really isnt bad for a vehicle with the earodynamics of a shoebox IMO .

You don't have to put the peddle to the metal just to get anywhere with the 2.5L. Maybe with some horribly oversized tires and stock gearing, or a horribly out of shape engine, but otherwise it cruises around town and on the highways perfectly fine. It's happy at 3000rpm and 70mph. I only drop the peddle if I need to pass someone.

Thw 2.5 gets better mileage off road I have found, but my 90 TBI is no better on gas driving around on the road than my 4.0's do, which is about 15-16 mpg. I have a 90 YJ welded rear spiders, 33" Dunlop Mudrovers, on stock 4.10 gears.
With this set-up it is a dog unless it is in 4 low. In 4 low it does really great, and will go anywhere, and is better on fuel while wheeling. This works out great for me as I do not drive it much on the highway

So I get about 170 miles on 12 gallons (about 14mpg). I just did a tune up (plugs, wires, cap, rotor) as well as changing the oil in the engine, tranny, front and rear differentials. (We couldn't get the transfer case open to check), and the driver side engine mount. What else should I check do to get better gas mileage.

I'm also putting Lucas in the gas. I used Mobile 1 5/30 synthetic with Lucas synthetic oil stabilizer and gear oil with Lucas oil stabilizer in tranny and differentials. Does anybody have any better suggestions?

Re-gearing for bigger tires is the best thing you can do after making sure everything is running properly. No matter which motor you have
