In the automotive industry for over 40 years. I have been using various products with Teflon additives for a long time. Slick does what it says on the tin, starts noticeably easier in colder temps, is quieter, can't say it uses less oil (150,000 miles on my truck). There is a friend who boasted about how little he spent on an oil change. He paid the price last winter by rebuilding a $7,000 Jasper engine. Treat your car right and you'll be smart.
