Anyone Familiar "Nano Pro MT Oil Stabilizer?" I've read it was designed through the military and it is some pretty good stuff. I want to add heightened protection to my 2004 Chevy Trailblazer with the Vortec 4200 VVT I6? it has 153,000 miles on it. I just bought it and since I don't know about the oil change history, I'm just guessing they ran regular conventional oil in the motor. I've only had the vehicle a month and despite the fact that it runs okay. I had to get the VVT sensor replaced already. I've read these engines are sensitive to oil condition. Thanks for any help.
