After build fuel mileage.

[wvyankee2]

Stock Overland Automatic with 32" factory rubber-- 20 MPG.

After 2 " lift, 35x11.50 (285/75/18 Falkens) , and 488 gears installed-- 16 MPG.

About 75% highway, 25% rural driving.

Power is great! Very happy.

2.5" ReadyLift SST lift kit, 1.75" wheel spacers with 315 70 17 BFG KO2 tires on stock wheels. Rugged Ridge spartan full width front bumper with Badlands Apex 12000lb winch. Mines a Max tow with 4.10 gears. I was getting 21 MPGs on the stock 32's and no lift, and now I'm getting between 18.3 MPGs, had it as high as 18.7 but not under 18. About 50/50 highway to city driving. I'm completely satisfied with my results. Haven't reset the computer mpgs since it had 800 miles on it which is when I recalibrated the computer after lift and tires.

I haven't checked my onboard to see what it says. Just calculated my fill up's. Last was 304 miles, took 19 gallon.

If I took out all the idle time I'd probably be getting closer to 19. I do a lot of sitting idle around my area, which I've noticed the mileage drops pretty quick when your just sitting. I've been letting the ESS do it's thing for the last 2500 miles and that has helped some.

I'll say this as well and not sure if anyone else has noticed after doing this. After I removed the section in the front that leads from the bumper to the fenders I could feel a little more wind resistance, on windy days in particular, that felt like it was dragging the jeep down slightly, not major but I could feel it. After adding the Rugged ridge full width bumper to the jeep and closing that gap back up, I feel like it's driving more closer to stock now on windy days. I could really feel the difference Friday when I drove home from work with it pouring down rain and 40+ mph wind gust. I was going to add the stock Rubicon steel skid plate on that I bought if I felt like the bumper and winch was affecting gas mileage a lot to maybe give it more of the stock aerodynamics, but I'm going to hold off for now. I feel like closing those gaps has kept it right where everything was at before adding the bumper and winch. That's based on 6 days of driving and about 275 miles. I'll report back after I get more significant miles on it.
