I want to let you know, this stuff is amazing! I bought an old Dodge Ram with the 5.9 Cummins engine, about 200,000 miles on the clock. It was very low on power, clouds of exhaust smoke , and had lots of blow-by. I got the FTC Decarbonizer from you and added it to the fuel. Seriously, within about 2 hours of driving, I could tell the power had improved noticeably, and the blow-by had reduced significantly. I was shocked at how well it worked! Now I’ve done about 1500 miles, and the exhaust smoke has completely disappeared, and it’s running much smoother! I’m getting the Flushing Oil Concentrate from you now to finish the job right.
