Hey guys,
I am new to this site, but have owned a couple of wranglers, and a liberty.
I have a question I just bought a 90 yj 4banger thinking this would be cheaper on gas and still fun. Well this thing needs it's own oil well.
I am getting about 4 miles to the gallon, at first I thought I had a fuel leak but I checked that out and everything is dry, (including the inside of tank:banghead Jeep doesn't run rough and idles fine. Any ideas?

Does it have a lift? What size tires are you running?

 

[Chris Larabell]

brakes sticking? low tire pressure? something causing to much drag???

 

[gunslinger1]

yes it has a 3" lift I am running 31 at's it had 33mudders but I want to pull my bass boat eventually with it the brakes aren't sticking just been replaced. The tires have nitrogen in them the pressure is fine brand new

Seriously 4 MPG or just exaggerating?

I will tell you from personal experience, a 4-banger YJ is not going to get much (if any) better gas mileage than the straight six. I've owned both and they're pretty much the same gas guzzling brick on wheels.

90 yj straight 6 .with 33's and no lift.. 13 mpg. Gotta be something wrong with yours somewhere.

How are you figuring you mpg? Are you using the odomiter in tbd jeep? If so don't, its probaly not right, use a gps. Next look at your o2 sensor, I was getting 9mpg with my 6 changed o2 sensor and back to 14. Have you done a full goin tune up?

my 4 banger gets about 17mpg with 31s no lift. 5 speed

I'm running a 4" rough country lift with 33x12.5x15 tires with stick gears and axles. I'm got 14.8 mpg today on this tank of gas.

Next time you see your neighbor out, go up and shake his hand.
See if you can detect any gasoline breath.
Even if you don't smell nothin on him, if he won't look you in the eye ask him if you can kiss his wife.

93 4.0 235/75/15 no lift, 17 city, 25 Highway(50mph)
