I use my truck for work mostly, 1200 miles just last week. gas mileage on I didn't notice a difference. At first, I went on a 600 mile round trip for work and didn't see a difference. The next trip was to the same place a day later, my fuel pump went out about 100 miles into the trip, After I got the fuel pump fixed and got back on the road I got 18mpg the rest of the trip,usually get 14 I have bullydog watchdog watching for me. Weather it was the fuel pump or the intake, 4mpg, ill take it!
