Description

Elf Moto Gear Oil 10W-40 is a semi-synthetic gearbox oil for two-stroke motorcycles with a separate gearbox. It can also be used where the motorcycle manufacturer specifies an engine oil for the gearbox, and it is designed for hard riding in any season.

The oil is rated API SJ; the data sheet cites no motorcycle manufacturer approvals. According to the data sheet, it contains no friction modifier, so the wet clutch does not slip. Gear changes stay precise and smooth even in cold weather, and the oil resists shear and oxidation.

Typical figures: 14.6 mm²/s at 100 °C, viscosity index 156, pour point -33 °C. Available in 1 litre packs.

Application

Separate gearboxes of two-stroke motorcycles, and gearboxes for which the manufacturer specifies an engine oil; hard riding in any season.

Worth knowing

This oil’s markings are those of an engine oil, SAE 10W-40 and API SJ, yet Elf’s data sheet calls it an oil for the gearbox of a two-stroke motorcycle. It claims no JASO class, the rating that is determined on a test rig with clutch plates. About the clutch the data sheet says something different: the formulation has no friction modifier, and it quotes users saying “the clutch no longer slips” by way of proof.

If, however, a four-stroke motorcycle in which one oil lubricates the engine, gearbox and clutch has a manual calling for JASO MA2, Elf’s Moto 4 series offers the same viscosity grade, for example Moto 4 Tourer 10W-40 with API SP. For the manual gearboxes of four-stroke motorcycles, the Moto Gear Oil line has a second oil, the mineral API GL-5 80W-90. The article on JASO classes for motorcycles explains how MA differs from MA2 and MB and how to check the class from the code in the box on the can.
