Tufoil has a pure synthetic base of the highest quality possible. The magic in Tufoil is the incredibly tiny size of the PTFE particles suspended in your oil.
We’ve got the answer and the proof! These photos to the right are taken through a Scanning Electron Microscope and compare the particles in Tufoil with the size of a human hair.
Tufoil’s suspension particles are 5 microns (0.000118″) in size so it mixes beautifully with your oil and can’t clog up your oil filter.
Tufoil for Engines is for use with 4-cycle engines.
Synthetic Oils and Synthetic Gear Oils and Greases: Over the years, Tufoil has always mixed well with all mineral oils and synthetics oils. Recently, however, we have seen an emergence of glycol-based synthetic oils. We are mostly seeing it in high-end gear box synthetic oils for high temperature applications. Tufoil is not always compatible with glycol synthetics. If in doubt, you can check compatibility by mixing 1 ounce of Tufoil and 10 ounces of your oil at room temperature and stirring. No wait time is needed. Tufoil should dissolve right into your oil with no settling or clumping. If there is no separation, Tufoil is compatible with your synthetic oil.
