3.0 and underdrive pulley MPG gain
Hi all , I have a 05 Edge 4x2 auto 4.10 gears 235/75-15 tires.
I was just wondering if the underdrive pulley will give me a little boost in MPG.
Anyone have hard numbers on MPG gain?
I'm getting 22.7 mpg highway and 19.2 city now .
any other mileage enhancers that work, I don't need more power as such, just looking for MPG boosters.
