Question Less MPG with Lift kit?

I'm hoping to go with the RRO leveling/lift kit if and once it's ready for MY14, but I was curious if you guys have noticed any loss in gas mileage since installing them.

What's everyone's experience? Thanks!

Re: Less MPG with Lift kit?

Of course you will. Larger tires + lift will always decrease your MPG significantly.

Re: Less MPG with Lift kit?

kk is correct...when you lift you are changing the air flow around (and under) the vehicle which changes how well it slips through the air at highway speed. The larger, more off-road focused tires don't roll as efficiently, are heavier (weight also decreases fuel economy...which is why there is a big push to reduce the weight on trucks, for example) and add resistance when turning because of how they grip the surface.

Re: Less MPG with Lift kit?

I guess I was really asking what type of mileage decrease you guys have seen just with say the RRO leveling kit as an example. I wouldn't be changing the tires if I didn't need to.

Thanks for the responses!

Re: Less MPG with Lift kit?

If you only add the leveling kit, and keep everything else stock, you may not lose much -- maybe .5-1 MPG on Highway, and unnoticeable in City. Most people lift in order to fit larger A/T or M/T tires. Hence the first reply.

Very true. If you do mostly city driving you're not going to notice the mpg drop the same as you would if you drive primarily at highway speeds as aerodynamics play a decreasing role in fuel economy as your avg speed decreases. Probably goes without saying, but there are so many variables that it's almost impossible to give an exact figure. Definitely, YMMV.
