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: 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.
The vacuum gauge plus wheel covers helped increase summer 2015 mileage to 38.5 MPG, while summer 2016 mileage was 38.6 MPG without the wheel covers. Drove 33,021 miles 2016-2018 at 35.00 MPG.
