Engine Blowby Pack Reviews

“Just a note to say the truck (5.9 Cummins) is running much better and smoother. The oil is still normal and clean after 600-plus miles, oil consumption is much lower now as well, and fuel eco is up. The Blow-by Pack has worked as you said it would. Thanks!” Marc M, Chico, CA

“Tell ya what! After using the Flushing Oil Concentrate the way you recommended, the engine oil is still as clean as new after about 600 miles! I’ve noticed too that the engine seems to be smoother and up on power – probably the FTC Decarbonizer doing it’s thing! (2012 Cummins ISX). I’ll keep in touch.” Marvin M, Lewistown, IL
