Series 60 Detroit oil flush

“Got the Blowby Pack a few months ago for my 60 Series Detroit, and did the engine oil flush soon after. I think its incredible how much sludge and other material the flush got out. I kept a sample of the original oil, then compared it to the oil that came out 45 minutes later (the flush treated oil), and it’s incredible how black it was! I couldn’t tell the difference between the 2 oil samples! 45 minutes earlier that had been new, clean oil. My mechanic was amazed at what he saw! Now, a few months later, the oil is still looking good, though starting to turn darker now. But it feels clean when I rub it between my fingers. The oil pressure increased and has stayed there over the time. It’s running good. I’m happy with the overall improvement. I want to keep this truck for a while yet. The FTC Decarbonizer will help that. Thanks for all your help.”
