I get around 38 - 40 with my setup, although I have to say that last summer I didn't keep track of mileage like I did the summer before. I went to Wyoming a couple summers ago and got right around 50 mpg on a trip through Yellowstone Park. I thought I had miscalculated, but I got the same on a second tank. I finally realized that Minnesota has 10% ethanol in almost all unlead regular. I think Wyoming's gas was/is 100% gasoline. That was the difference.
