Tufoil Engine Lubricant is Guinness Book of World Records certified as "The World's Most Efficient Lubricant." Slipperier to make engines start easier, run cleaner, faster, and longer. Tufoil engine lubricant has been tested by the US Government at the National Bureau of Standards. Their results prove that the surface friction of Tufoil (.029), makes it the most slippery substance known to man! Tufoil is a super-suspension of micro-miniature PTFE particles and soluble Molybdenum, permanently suspended in oil. All moving parts become coated with PTFE particles which reduce friction and wear and will not clog filters or oil openings. Safe for all gas and diesel engines. We recommend you change your oil and filter every 3,000 miles. However, many of our customers find that their oil is still clean at this point because of Tufoil's ability to cut friction and wear. They will then make the decision to extend oil changes accordingly.
