I have an 01 auto 4x4 4.0 with 4.10LS and for 4 years or so I've gotten 18-18.5 MPG on the highway and 14 or so in town. I started noticing my mileage go up since last month even city mileage was impressive. The only thing I've done Is stop using seafoam and switch to Gumout multi system tune up. I've used seafoam over 5 years and I've never seen any change to my mileage. I started using Gumout 2-3 months ago so far I think I've used 3-4 cans of the stuff with the last can on a half tank of gas. i used to get 40-45 miles to a 1\4 tank of gas,on this last tank I got 56 miles on a quarter tank. I put 236 miles on this last tank and the gas gauge was still above red. Generally on a full tank I'd usually get 180 to 200 miles and it was on red. I do not work for nor am I affiliated with Gumout, I'm just letting people know my experience with the product and the fact that I see results in fuel mileage vs. fuel mileage results with Seafoam. I have the factory fan with a severe duty fan clutch,stock size 245/75/16 tires,and i haven't cleaned my MAF in over 6 months..yes when using the seafoam I'd clean the MAF at least every 3-6 months in hopes of seeing MPG gains but I didn't. I still have a rough idle that i can not figure out,and no vacuum leaks can be found..I've had the common vacuum leaks in the past
