Coastdown testing proves this definitely has an effect. Where I normally hit 35, I was coasting at 37, and it looks like the fuel gauge isn't dropping as far after the usual commutes. I've gone about 200 miles so far on this tank, and I still have a little under half a tank. Before, I was lucky to reach 300 miles before E. I usually refill the tank when it's about 1/8 on the dial, and it takes 10 gallons to fill it. To get a ballpark estimate, I just move the decimal place over one place to get my tank MPGs. I still have a ways to go, but I'm guessing this will come close to 30 MPG.
