the money we spend on gas for our jeeps is a lot less than we would spend to keep up with parts and problems of a rice burner though....im just sayin.

LJ Trek Top?

I'm reposting this since it was the last comment on the previous page in hopes somone will see it.

Just out of curiosity has anyone here with an LJ tried the "Trek Top" by Best Top? The reason I ask is that this has a slanted backside for the jeep and the LJ's in particular have the most sloped backend. I've been thinking of getting one because i like the look and from an aerodynamic perspective they should create a fairly noticable difference when doing highway driving. The regular TJ's and X's probably wouldn't notice as much as the slope of the rear is not as gradual as it is on the LJ's.

Ok so it really boils down to... is that is depends on the car.... I had a 95 BMW 525i that got 33-35 on hwy...avg 26-28, put a K&N lost Gas mileage and power.... had a 94 ZJ with 4.0 auto, avg 22-24, and is faster then my 00 TJ 4.0 manual...as far as get up and go.. TJ avg 14-15 and it's stock... however I did notice that at 80+ the gas mileage dropped a lot even with a egg under the pedal. I do believe I need a tune up and hope that helps not only mileage but power as well.... hubby says I need a cold intake, performance chip and something to do with my exhuast... and that will help with power which will help with mileage.

easiest way to improve gas mileage is lighten and lift your FOOT!!!



don't tromp it from lights, and slow down on the highways...

Lighten your load by removing those unnecessary stuff and tools. Also, don't accelerate so hard.

since no one is answering on the nitrogen........ with nitrogen, the molecules dont expand and contract like shop air in the tires, therefore keeping fairly close to the same pressure all the time in your tires. with shop air in the tires, the pressure has been known to increase up to and above 5 psi. hope this helps you armymedic.

I am runnin my XJ with 4 1/2 lift, 32 at tires at 25 psi, 4:10 gears, and an auto. I consistently get 15 in town and around 18 on highway.

with the ZJ, all stock with 235 on it, I get 20 at 80, and usually get around 18 in town. used to have a mitsu galant that got 30-35, but I hated getting stuck in the driveway all the time in winter. MPG's arent worth it if you cant go anywhere!!!

JEEP.......not just a vehicle.........its a lifestyle!!

It's also nearly imposable to get 100% nitrogen in your tires.

Install a vacuum gauge. Old-school, barometric models use a piece of vacuum line connected as close as possible to the intake manifold. (I usually just tee it into an existing line.) They can be had for under $20. Newer electronic models use a sensor/sending unit to control the gauge. I can't vouch for them, I've only ever used the barometric models.

To use it, pick a number on that gauge, and don't let it go below. In general, the higher the number, the higher your MPG. It's amazing to see how much that gauge wants to drop just to get rolling, and how long it wants to stay down there while you accelerate.

I saw 2-4mpg gains in my old S10 just by slightly altering my driving style. Haven't added this gauge to my jeep - I've only had it about a month and we're still just getting to know eachother.

our air is made up of a majority of nitrogen. the whole 100% thing is stupid.

Many people will say that accelerating slowly is a good way to get better mpg, but that actually isn't the case. What works the best is to accelerate quickly into second gear, the slowly build up speed from there. Cars are least efficient when they are running at really low RPM, low speed, and low torque. You need to spend as little time as possible around the lowest end of the spectrum. When you're at 0 mph, all the gas being used just keeps the engine running, and it's not used to overcome external forces (friction, weigh, air resistance, etc...) at 5 miles per hour, the jeep is running at very low rpm, and most of the gas is used just to keep the engine from dying. Once you hit 10-15 mph, you're primarily overcoming the normal force between your car and the road, and almost no gas is used solely for the purpose of keeping the engine running, that's when you should stop accelerating as rapidly and let the car slowly gain speed up to the cruising speed.
