Interesting testimonials on amazon about the use of Tufoil. Just for the 8oz size there are 21 5 star testimonials. I know Tufoil is a touchy subject on BITOG but I use it and I find that it works very well in cutting down friction(via temp reduction)and vibration as well a minute increase in fuel economy. I am a satisfied user since 2005.
