What can I do for better gas mileage

After reading around a little bit I know people on here get a laugh at mpg questions. With this being my day to day vehicle I could use the better gas mileage.

I have the 01 auto 3 speed 2.5L 4 Cyl all stock wrangler. I'm getting about 15 combined mpg. What are some after market parts I could get that could possibly help with gas mileage?

Make sure the tuneup is fresh and clean the throttle body.
I get 17-19 with my 2.5, 5 speed on 31's so you should be able to pick up some ...not a lot

No aftermarket addons that claim to increase MPG or Performance work. If you feel the urge to spend your hard earned money on a snake oil product you should do a search on this forum first. Or else you can find out first hand but I am sure none of them will refund your money when you realize you were duped.

Lighten the load. Take out everything you don't absolutely need (spare tire and mount, rear seat). Won't help much but you might see 1 or 2 more mpg.

Kind of like buying something when people say "Good, Cheap or Fast...pick two..."

Economical or offroad capability...pick one...lol

Drive it like a little old lady. The more you push it to keep with traffic the lower your MPG. When I was commuting 100 miles a day I never was out of the right land and never went over the speed limit. Even driving like that my personal best was a little over 19. Even after having to stop to fill it up every 3 days it was still my favorite vehicle. But then after 31 years with the corp I worked for they laid me off and my MPG dropped driving around town now and then with my dog but I only have to stop for gas once a month. Everyone keep working so my social security checks keep coming.

Yup that'll give you better MPGs

I'm thinking it'll make you tougher as well. Putting tires like that on a Jeep would be the equivalent of naming a boy Sue

After a tune up the thing that will help you the most is how you drive. Jack rabbit starts kill mileage and going over 65 does the same. Jeeps will never be as fuel efficient as cars no matter what you do to them.

This! I've heard of 6BT swaps getting about 35MPG. If my 242 ever shits the bed on me, I'm doing a 6BT.

I'd throw a party if I got 15-17 mpg. I have an 97 wrangler sport with the I6 4.0 on 33 inch tires and 488 gears. I get 10 mpg at best. If your looking for good mpg, a jeep wasn't the best choice.

If your only getting 10mpg I'd say you have issues. Lol

I see in your profile yur in CO, I have always wondered how living in areas of higher altitude affects performance in the jeeps.

If 10 mpg is bad then tell me what's wrong with mine cause I have the 2.5 l with a 3" lift and 31's a and I get at best like 11.

You could also do a Seafoam treatment...cant say it will increase it dramatically but it does clean out the crud...

I've got a 2.5 5 speed, 1.75" lift on 31's and get 17-19...
Do you have the correct speedo gear so your speedo reads correct and registeres the actual miles traveled?

Just watch how you drive, lighten your foot up. I swear every time my foot gets a little heavy I notice a difference in gas mileage right away. It's all about how you drive it to me

I have a 01 2.5L and I am getting a K&N Filter today... Has anyone used these with any such luck?

I am getting 15/16 mpg now...

I'm driving a 01 with auto/3.07 gears & 33" tires as a DD & get 15-16 consistently. I did replace the plugs after I bought it & used the recommended NGK.

I've had a K&n and an off brand filter from advance auto, they both worked identical, no problems what so ever, except the K&n crushed on me during cleaning. It definitely does make a difference, but your gas mileage probably won't be TOO much better. You might make your money back in gas in a year or a little less. It'll sound a lot meaner though. Definitely worth it in my book

K&N filters don't mix with Jeeps because it lets too much crud enter the throttle body.
