Alright so I just picked up my F-150 it's lifted and on 35s so I know that kills gas mileage there, at this time I'm getting 7 miles a gallon. The full tuneup was done last year. Any suggestions to better my gas mileage?

That sounds way to low…do you know what gears you have?

LiftedTeal95

No idea

I would start with taking off the lift and the 35s.

LOL, good one

check axle code on door jam sticker. also if you get underneath the back the axle should have listed on it what gear ratio it has. If everything in that area is still stock

its a 3.31

The 3.31 is killing you and your speedometer is probably off if you have not re-calibrated. If you have not done this then your calculations are off. If you have done this then a re-gear is in order for you. 3.73s or 4.10s will put you in your power band and reduce strain on your transmission.

Ill look into it, thankyou. I have 3.73s in my mustang. Maybe ill go with those!

What trans do you have? I put 35s on one of my trucks with 3.55s and wasn't able to use overdrive unless I was going down hill. That killed the mileage until I got new gears.
