Has anyone changed O2's and seen a mileage increase even though they were throwing no codes.
My rig has just over a 100K and I think my O2's are original so I was just wondering if it would be worth it?
I was getting around 14 MPG before with mixed driving.
My mileage has dropped of a bit the last couple weeks, but that maybe if they are selling the winter formulated gas already?
