I know i shouldn't worry about MPG's on a truck...lol, but I really haven't found any threads on MPG's with lifted trucks here. Looking at 6" or 7" lift kit MPG's...preferably with the ecoboost engines. Thanks!

 

You're going to take a substantial hit. If you care about the mileage, don't do the lift.

 

It's not necessary the size of the lift. It's the size of the tires.

 

I was thinking of some k02's 35x12.50x20 with the lift. Haven't seen any pics of a lifted truck with those tires on them. I know they weigh less than m/t's. More of curiosity of hit to mpg. I have my truck leveled currently with 1.5" autospring and stock tires and i get around 20 mpg overall. I have the 2.7l ecoboost.

 

^ THIS. If you can't afford to pay more for gas after a lift, then don't get the lift. It's guaranteed you will lose MPG's. Pretty easy decision.

 

Likes been said, its not the lift its the tires. 35"s are bigger and heavier and will drop your mpgs. Its different for every truck but the switch from stock to 35"s will likely result in around 2mpg lost. That's just an average of what I hear everybody say. I went to 34.6" tires (or something like that) that are likely a bit heavier than what you are buying and I lost about 2mpg.

 

^Agreed, if you are planning on lifting your truck, MPGs will suffer.

 

It's both. The lift messes with the aerodynamics by letting more air run underneath the body, which is not exactly a smooth place for air to flow. I lifted my Xterra before putting on the new tires and had an immediate drop in MPG's on the highway. Once I put the bigger tires on, it dropped even more, but the tires affected city stop and go mileage more.


So, lift = worse on the highway.
Bigger tires = worse in the city, slightly worse on the highway.

 

It's an all around MPG loss.. got to pay to play.

 

You could argue bigger tires = slightly better highway, since you are essentially putting on taller gears
