What else can I do?
Hey MiddleORoad, I think you are right. I'm getting 15 m p g in a 2007 Sequoia. It has a 4.7L but also a towing package with 17" wheels and 4.10 rear end gears. It has all kinds of torque, but it runs at 2500 rpm at 70 mph. I think if I can get it down to 2000 rpm, it will improve dramatically.
Does anyone know how to calculate what kind of mile age a higher gear ratio might get me?
The problem is, a new set of gears costs about $800. It sure would be helpful to get an idea of my savings before spending that much.
