Tips for Better Gas Mileage....

supr_bikr_99 · 08-29-2005, 09:26 AM

Figure this had probably already been beatten to death as a topic, but what the heck! Just wanted everyone to share ways that they get better gas mileage in their rig. Mine has been not doing any unnecessary driving, LOL. What mods/tricks have you all used to get a few more miles per gallon?

Drive gently. The plain fact of the matter is that there isn't anything you can do to your Jeep, or anything you can put in your gas, that will make even half as much difference to gas mileage as what you do with your right foot.

I agree. No more than 1/4 throttle. Yes, it takes longer to get to speed, but this is not my drag car. I get 18-20 mpg regularly.

Drive slower!!! (nothing works better)
75-80 miles per hour I get 15-16
at
60 miles per hour I get 17-17.75

keeping up with routine stuff like changing fluids, spark plugs, air filter, propper PSI in the tires yadda yadda yadda

Very true, there is no substitute for leaving the lead shoes at home. I don't do too bad with that, generally 18-19mpg on the highway. City sucks though. It seems like my gas mileage has dropped in the last year. I used to be able to go 350 miles on a tank for the city and highway driving I do. Now I only get about 290-300 miles on a tank. I still take the same route to work and the gym. Anyone else had this happen to them? My TJ just turned 100,000 this weekend, but it's been like that since about 80,000. I'm going to do a tune-up this weekend, so maybe that will help some.

Tune up will definately help. If the plugs and wires (if you have wires, don't know what year yours is) are going bad, and if anything else is bad, dirty air filter, etc. then you aren't burning the same amount of fuel. The computer sees this loss of power and dumps more fuel into the cylinders. If it sees it burning more efficiently again, it will lessen the injector on-time.

slow and easy, I rarely shift above 2500 rpm, rarely drive over 60mph unless on interstate. I consistently get 21 mpg. 2002 SE 4cyl 48K miles

But I bet you have stock tires, right? I have 33s and 20 mpg is only a dream. I get 12. Maybe 13 if I am lucky.

same principle applies, whatever size tires

I know, but I still bet he has stocks tires.

nbf6165 · 09-05-2005, 10:40 AM

yeah man, I have slightly larger than stock tires.(235's) I'm not saying you can get 21mpg. The fact is if you drive slower and easier, you will get better gas mileage. That is a fact. My jeep is my main vehicle, I drive 50-75 miles at the very least each day. For this reason, I chose not to get large tires.

camarkim · 09-05-2005, 10:49 AM

Here's another theory I'm testing. (We'll see after I swap out thermostats.) My thermo might be stuck open, which may be the reason my YJ run cool. If it runs at normal temps after the swap, then ostensibly it will lean out if/when it gets to operating temp. (i.e.-cold idle means computer is richening up the mixture.)

(OTOH-Last time I filled up, I showed 179 miles/7 gallons=25.5 MPG, so, maybe it's getting up to temp after all.)

I would probably do the same. I have a 4 banger. That means that I basically have it floored at all times. That obviously is not good for my mileage.

I don't know if these have worked yet-took of my hardtop, removed 33in spare, took out my back seat, put a k&n filter(I know the debate) and I stay out of the gas, people will not run over me they just pass and wave with only one finger. It beats hugging my buddy when he rides his moped.
