cj daily driver?

I have always loved cj7s but have never owned and would someday like to. But, i need to know if they are reliable as a daily driver and with the price of fuel where it is, i'd like some feedback on fuel economy. i would like as much input as i can get about these things. thanks

i love cj's, they're gonna be a little less efficient than yj wrangler. if you don't know much about carbs, don't bother, or upgrade one to fuel injection right away. i'm a mechanic, and would love to own one, but i bought another yj cuz i just don't want to have that much to do all the time.

A friend of mine fully restored an 86 CJ7 with the T5/258 combo. It's his DD and now he's crying poverty because he can't afford the gas...he spend 20k on the restore.

If he sells it, I'm jumping on it.

Check out his pics from the restore...

you would think that with the six banger and overdrive fivespeed the mpg's would be better, but i guess it also depends on tire size, axle ratio, and driving style...

He has the stock axles/gears with I believe 32" generic A/Ts. He has the Weber carb and gets 12MPG. He also babies it. No highway driving and no dirt. He waxes the damn thing.

My '87 YJ got fuel mileage in the single digits, and I still filled it up EVERY DAY. Used to cost me $60-$70 a day.

^^^ What they said. If you want to drive a CJ, then drive one. If you want a fuel friendly dd, look for a yj or tj w/ a 4cyl, 5 spd, stock diameter wheels and tires.

83 CJ-7 stock all the way around. With teh 258 and a 5 speed. Was daily driven from new up until a couple years ago. Driven normally and not at outrageous speeds and would consistantly get 18-20 mpg.

Everything was stock from the factory. My dad never changed tire size. Just did maintenance as he should and I know where it is now and is still getting 18 with over 160k on the odometer.

I would imagine it was somewhere from 3.07 to 3.73.

I drive my '85 CJ8 every day with a carbed 2.5 and a 4 speed and I'm getting almost 20 mpg (mostly highway). I honestly don't have a clue as to the gears, I just got it 2 weeks ago. YJ's aren't any better, I had a '95, 2.5, 5 speed with 410's and It didn't matter if I had the 225/75/15's or the 245/75/16's I never saw better than 15-16, also mainly highway. It's all in the way you drive and the amount of additional weight/lift/oversize tires on the rig. My YJ had some extra weight (rock bumpers, 1/8" rocker guards with curb feelers (rock rails) so that could have been the diff.

Does a 2.5 have any good power, or just enough to get around?

I had a 64 cj5 I drove in the summer months for awhile, Not sure what kind of mileage i got, but I do know I was at the gas station a lot.

I had a 1987 wrangler through 1994 when it was totaled in a wreck. It was the carbed model, did not yet have fuel injection. It got considerably better mileage.

From a safety standpoint, get into something newer. If My wife and I had been in the cj5, we would have been toast. The wrangler actually saved our lives on that night.
