If my KJ has the 18.5, any ideas why the gas light comes on after only using about 14 gallons? Is that normal?

Thinking about buying a Cobra® 29-LTD 2-Way 40-Channel CB Radio. Anyone have install/antenna suggestions?

I'm lucky if I get 230 miles until the light comes on
Same here I get like 13mpg in city and only get like 250 miles to a tank. We just had the fuel system cleaned and still crappy mpg

I was the same. I switched to a tough guard air filter, new spark plugs, changed oil and fluid in everything (diff, transmission, xcase) and now im at about 15.

60mph... that's not even moving! Mostly I'm driving about 90 or 95 mph (when I'm not in the city of course). If I drive conservatively then I can go about 380 miles before the light comes on. But to be honest I just fill my KJ when she needs it and try not to worry about the $9 a gallon gas.

What happens in my KJ stays in my KJ °llllll°

I have never actually determined how far a tank of gas will take me
But I do know since regearing its 270 miles from where I live to my home place on mixed roads from one lane gravel to some town and 4 lane. Speed from 5 MPH to 75 on the 4 lanes. When I get there I have about 1/4 tank left. Low as I ever take it.
Amsoil filter in the stock box, good plugs every 25-30,000 miles, all upkeep done, and lots of heavy parts hanging on it

I've hit 4 deer with mine now plus a Toyota Camry
That ARB up front takes care of them all and just a few scratches

Going to throw another one out there, I also use ZMax, know for years as LencKite, used in the air craft industry to keep carbon build up down, all the post about yellow sludge in their oil cap, the LencKite brakes it down, had a valve cover leak, when I pulled the cover off the head was nice and clean, no carbon or sludge, and no more yellow sludge, you will hear the pro,s and con,s on engine additives, Let Them Begin

Yeah use quality oil and no snot under the fill cap,also changing the PCV valve often helps also.10 years and never had that snot under my fill cap.
