35's winch bumpers / chipped etc and get consistently 425-450 a tank (almost empty) and fill it up every 2 days mix of hwy / city . Oh well it's a jeep !

 

ill pray for you my friend and im not a religulous guy hahahaha

what gears are you running?

 

I've now gone 3-4 tanks, all city driving and I struggle to hit 350kms per tank. This past week we've had a ton of snow so it's been in 4HI and i'm getting 16.4L / 100kms!!

 

P1llar, let the motor break in. The OEMs purposly run the motors a hair on the rich side till they hit 10-12k. This is a commont complant with many new vehicles, so your not the only one. Also from what I remember from my level 4 auto mechanics training, 91 burns slower and produces a broader flame front, it dosnt burn faster.

 

When I run the higher octane with my superchips programmer i get better gas milage.

I'm getting 13-14 withe highway/city. That's with 35's and stock height. If it's just highway it's down to 12-13. Now that it's cold and I warm it up I'm at 16-17 ouch

 

I'm at 5,500kms or so. When my gf would drive it through the summer we were getting 425-450kms easily, 13.5L per 100kms. Just seemed over a month gas mileage signifcantly when down.

 

I've got a 6 speed with 33" rubber, 24, 000 KM on the engine, a Gobi roof rack, AEV corners, ARB diff covers, Poison Spyder Evap skid (about 230 lbs total weight).

Right now with all the snow we've had and lots of 4hi driving I get about 350 km to a tank. I found in the Summer I was getting about 380-390 kms to a tank.

When it was stock I got about 420 kms to a tank. I've been thinking about getting a superchip to hopefully regain some mileage.

 

lol, thanks for the mental support JH
Stock right now, but next year I plan to change them so I am hoping the mileage should change a little..but the other problem is if I am changing the gears I might want to go with 37's at that time so any mileage gain will be lost yet again..
