Just to give some information so everyone knows. Most people are saying either use ac or put windows down...but it depends on how fast you are going. If you are highway driving, around 50mph or higher, use the ac and put the windows up. If you are doing city driving (less than 50 mph) turn off the ac and put the windows down.
how much is my mpg going to drop with bigger tires? I have 31" tires on my 2" lifted jeep and already get crapy gas milage. when i install my 4" lift this weekend i need to buy bigger tires. i was thinking around 34-35 x12.50. is this going to drop my mpg drasticly. Does the width of the tire effect it or the height?
Theres alot you can do to get better gas milage. Hell ive seen straight sixes get 40MPG/HWY.
Ill use my cressida as the example. Being it was a 2.8l, it still go the same milage as the jeep.
-Dual Electric Fans, remove the clutch driven one.
-High flowing cooling system, less drag, equals less power loss through the accessories.
-Training, tie a string from the pedal at 1/4 throttle, to the something strong. Helps get rid of the lead shoes.
-Manual transmission, depending upon your driving habbits
-Light weight rotational matter. Light flywheel, light driveshaft.
-3.73:1 gearing on 31" or less tires
-.5-1" larger exhaust. I ran a 2.5" on the stock 2" with a turbo muffler.
-More flow, if you can get colder air, and higher flow, youll amp up that milage.
Now it might sound like youre building a race car, but you arent messing with anything fuel. The computer will still handle this, and not run rich.
Doing this I got 35MPG/HWY and vehicle rated at 23MPG/HWY
Makes for a fun ride if you wanna jump on it because you have the stuff for speed, but also the stuff for economy.
i have noticed that i actually get better gas mileage if i accelerate about 3/4 throttle then set the cruise at operating speed of about 77mph and change the oil every 6000 miles rather than 3000 with synthetic. went from about 17 to 21 driving this way. seems strange, but i do all interstate travel about 80 miles a day. in iowa it's pretty flat terrain, also removing the roofrack and stock tires probably helped a bit, 21 aint bad!
but neither is 17, if you are that worried about mileage buy a honda!

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?
best way that I have found is to just be easy on the gas
You could buy a 15 year old Honda Civic for like 600 bucks and only use the Jeep for fun stuff.
I know, crappy suggestion, but with gas at 3 bucks plus, what do you want?
Teehee! Thats what I did. I got a 93 civic for 700 bucks. Great for the long travels and stop and go traffic. Now if I could just find a bumper sticker that says my other car is a jeep. To keep the babes informed that Im not a rice rocket pudd.
