Noticeably less smoke

“I did the oil flush with great results as far as noticeable sludge. While not 100% free of sludge (oil now has slight dark grey tinge, but does not stain fingers when rubbing together), but the difference before and after is really striking, great product! The performance and lowering amount of smoke at start up are…

2012 Kenworth W900

“I run a 2012 Kenworth W900, with around 340,000 miles on it. My buddies lately have been getting hit with massive repair bills on their trucks – it has crippled some of them. They’ve been telling me I’m gonna be next as my truck is at the mileage when things start to go bad. I do not want…

Freightliner fix

Chevrolet Cruze Diesel engine oil

“Just thought I’d send you a picture of the dipstick approximately 700 miles after we did the engine oil flush with the Flushing Oil Concentrate. The oil is still so clean I can hardly see it on the dipstick. I am still amazed at how well it cleaned out the sludge and other muck in my 2010 Chevrolet…

Cummins ISX

“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
