Here's my offer. Give me a Diamond Lube kit for my truck. I'll test it for a year (summer 2014 and winter 2014/2015) and add the results to my build thread: http://ecomodder.com/forum/showthrea...yon-17070.html. A 3% improvement will show up, a 5% improvement will jump out. Slightly over 10% will get me the 40 MPG summer mileage that I would really like to get.

If it gives me 5% MPG improvement, I'll then pay you double your current list price. Put up or shut up.
