Talked to several people running his BIO and they love it. One has a 02 Cummins, 04 Dmax and several 7.3L Powerstroke. Most have seen atleast 1 MPG increase. Going to get my first 20gal sample on Friday. $2 per Gallon He also treats his BIO with Power Service Additive. His winter formula has been tested down to -5 degrees.
