Description

77 Lubricants Motorcycle Oil 2T Extra is a semi-synthetic oil for high-output air- and liquid-cooled two-stroke petrol engines. It blends mineral and synthetic base oils, and the formulation is designed for low smoke and low ash.

The oil meets API TC, JASO FD and ISO-L-EGD as well as the TISI standard; the data sheet lists no equipment manufacturer approvals.

Typical figures: kinematic viscosity 9.1 mm²/s at 100 °C, viscosity index 123, pour point -36 °C, flash point above 90 °C, sulphated ash 0.14 %. The oil is fed by an injection system or mixed with the fuel.

Application

High-output two-stroke petrol engines, air- or liquid-cooled, with metered oil injection or pre-mixed with the fuel.

Worth knowing

Of the four data sheets in the line, only this one mentions liquid cooling directly: air- and liquid-cooled engines are named side by side in the description. The data sheets of the mineral 2T and of 2T Extra Red speak only of air cooling, while the SYN 2T data sheet lists the kinds of machine it is for without naming the type of cooling. The codes in Extra and Extra Red are identical, API TC, JASO FD and ISO-L-EGD, and the viscosity at 100 °C is 9.1 mm²/s in both; the TISI mark appears only on this oil.

A mention of liquid cooling does not make it an outboard-motor oil. For liquid-cooled outboards the manuals usually require TC-W3: a certification programme run by the American association NMMA, under which each registered oil receives an RL number. TC-W3 is not among the codes claimed here. How TC-W3 differs from API TC and where to find the list of registered oils is explained in the article on two-stroke classes: JASO, ISO, API TC and TC-W3.
