Re: My gas mileage sucks!!!

I didn't buy my jeep for the mpg, just like I didn't buy my vette for the backseat.

Re: My gas mileage sucks!!!

Hey Grim,

I just made up my mind to get a 3.0CRD Ltd and have it chipped, i was wrestling with getting a Hemi for the awesomeness but i do high mileage and it would just kill me.

I can just about live with my Jag 4.2 which returns an average of 21mpg.

I did think about an LPG conversion but never had one so i am a bit reluctant.

Where are you in the UK?

Reecy

Re: My gas mileage sucks!!!

Yeah I feel your pain man, many do, they are Jeep after all haha. For me I think the suspension killed mine id have to say, the huge drop and the heavier brakes/wheels along with the way i drive, I'm lucky to get 10mpg and I'm driving the v6 haha. People dont realize every mod they make may effect their MPGs and usually its for the worse haha.

Id figure the suspension mods would help but physics experts have explained to me the way it works and the geometry now makes for a guzzler, the heavy rotating mass from brembos and 20" wheels don't help much either.

I must say at best I can get 14-15mpgs but I drive like . . . well a 21 year old with somewhere to be haha, so 9-10 it is haha and I roll on and keep the wallet full

I was all freaked out at first until i realized that until it donned on me that its a calibration issue more then a real issue. I still fill up the same time every week.
Did you get your SPeedo-recalibrated for that tire size? I have the same tires on my diesel and I am getting 16 city, 20 highway. I was getting about 19 and 23 on the highway with my original 245's. The dealer recalibrated my speedometer but I think they could only go as high as 255 size but it was close enough for me.

Re: My gas mileage sucks!!!

Marlon told me to put my tires at 40 PSI and I would get the best gas mileage out of my 3.7. When I did it, I was getting 17-18 MPG. Can't wait until the summer blend gas comes through my tank, I could get 20 MPG on a daily bases
