Shannon, I have used Teflon based oil products in my cars for years. Oil and manual transmissions. The only problem I had was at the inspection station when the car had a hard time heating up to pass emissions. The man asked me if I had Teflon in the car and I said yes. Then he knew why it was harder to heat up. Follow directions on the can and make your oil a little slicker.

Has anyone used this and has it made a difference in care/performance? >>
