    Looking through old posts for answers to my previous post, I noticed several gas mileage related posts and thought I'd add my two bits.

    Switch to synthetic oil! I had some extra Mobile 1 20W-50 laying around from my race bike and thought I'd throw it in the truck since it trashed my clutch on the bike. Man what a difference!!! I kid you not.

    The engine ran what I'm guessing is about 20 - 30 degrees cooler...all the time! Less heat means less friction. Less friction means less fuel to turn that motor around. I gained what after several tanks of gas seems to be right at 2 mpg out of the deal too. Less friction also means less wear on the engine :)

    Sure the cost is a little more than double...but you can easily go twice as far on the stuff. I'm changing mine every 5k to be on the anal retentive side.

    Just my $.02,
