6/16/08 23.6 miles, 12.227 gallons (87) 19.02 MPG - This was almost exclusively highway driving at about 80 MPH, plus a little bit of to and from highway. By far the best tank of gas I've ever had, but still not really out of the normal range for this truck.

Tomorrow my truck goes in the shop for the FABTECH install, so this is the last tank that will be comparable. Will keep using product, at least until next oil change and will be interesting to see how the lift affects the MPG.

So I guess my conclusion (for this limited test) is that the MMO may have helped a little, but certainly did not hurt any, and for $3.99 /quart it is a much cheaper option then the Ethos.
