Thumbs up Gas Saving Tips For Jeep Owners



Good Tips for Jeep Owners:

1. Maintain oil levels constantly (less oil can burn gas faster).
2. Work on keeping clutch in when coming to a stop sign or stop light (IF you have a manual transmission).
3. Fill tires with hydrogen rather than air. it keeps your tires inflated longer and does not corrode your tire walls.
4. let your car heat up before driving. this saves gas!

MORE TIPS COMING SOON!

I think you mean Nitrogen. Hydrogen is a tiny molecule that can escape the tire even more readily. And more importantly hydrogen is *extremely flammable* and would likely result in you tire(s) exploding in a rubber & steel shrapnel mess.

No actually, it doesn't. If you are idling and not going anywhere, you are getting ZERO mpg. So even if you aren't getting your full mpg because you are driving with a cold motor, it is still an improvement over zero mpg.

1. oil quantity doesn't change how much gas you burn. you'll burn as much gas if you are 2 quarts low or 2 quarts overfull. the difference is that if you're low, you run the risk of oil starving the engine which, incidentally, has much larger repercussions than decreasing your gas mileage ;-)
2. ya, same with every other car in existence...
3. that would be nitrogen you mean. keep in mine tires under 5 years old don't leak unless there's a hole (or you have chrysler chrome rims that don't seal) and it's technically illegal to have tires over 5 years old on your car in most states.
4. every second you spend idling without moving is a second of operation wihtout moving...0 mpg. yes, you do get better mpg once the engine's warm but only if you don't count the time spent idling to warm it up. the best way is to start the engine and let it sit for maybe 10 seconds to let oil circulate, then start driving taking it easier than normal driving for a minute or 2.

in short....why is this even up here? it's all wrong or listed elsewhere... many times over

As a Jeep owner....

1) If the crank is running through the pan and causing the oil to foam up that makes sense. Else I see no point in slagging my engine due to low oil. Nor have I ever heard of someone improving their MPG running low on oil.
2) Our ECUs are retarded, we don't go into fuel cut unless its one hell of a decel. Dropping it in neutral is a better idea unless you need the engine braking.
3) Nitrogen, I think you meant, since regular air is about 80% nitrogen already, and a nitrogen tank isn't free, don't see much of a point going for 100%
4) The 4.0 uses 0.6 gallons per hour idling, idling to warm up is a royal waste of gas

Instead of idling in cold temperature, use a wonder of science, a block heater. Two or 3 hours MAX and the car is ready to drive.

Welcome to GasSavers. It's good that you're working on improving fuel economy. You can learn a lot from this site. See the stickies at the top of this forum.

Clutch pedal down should only be momentary. Holding it down causes wear and stress to the clutch throwout bearing and can cause its premature failure. To 'unload' the engine, put it in neutral till you need it again.

Use clutch to shift into neutral at the earliest opportunity. That is, when possible, coast/roll to a stop with engine idling. Saves fuel when compared with approaching stop under power and then braking.
