Tufoil Engine Treatment (48 oz.)

Tufoil's claim to fame is measurable. In 1996 and 1997, the Guinness Book of World Records named it the World's Most Efficient Lubricant — a designation backed by testing at the U.S. National Bureau of Standards (now NIST), which recorded a steel-on-steel friction coefficient of 0.029. Fluoramics also cites Canadian government cold-weather testing that showed approximately 10% improvement in cold cranking speed and a 5% fuel savings.

The additive works by suspending PTFE particles in a PAO synthetic base. Fluoramics' founder spent 10 years developing a patented method to keep particles under 1 micron in size and in stable suspension — too small to clog an oil filter, and sized to stay mixed in the oil rather than settling to the pan. Six U.S. patents and five international patents cover the suspension process. The 48 oz bottle is the bulk format: for a standard 4- to 5-quart crankcase, the initial treatment dose is 8 oz (1 oz per quart). At subsequent oil changes, only 4 oz is needed. The 48 oz bottle provides multiple initial treatments — useful for fleet vehicles, high-oil-capacity diesel engines, or keeping a supply on hand for ongoing maintenance.

Compatible with conventional and PAO-based synthetic oils (Groups I–IV) and with 4-cycle gasoline and diesel engines. Not for 2-stroke engines. Fluoramics does not recommend it for engines with wet clutches, where reduced friction can cause clutch slip.
