Description

Shell Advance AX7 15W-50 (SM/MA2) is a part-synthetic oil from the Advance line for high-performance four-stroke motorcycle engines, air- or liquid-cooled, with an integral gearbox.

The oil is rated API SM and JASO MA2; the MA2 class stands for the friction properties a wet clutch needs. The data sheet lists no official approvals from motorcycle manufacturers.

Typical figures: 19.2 mm²/s at 100 °C, 149 mm²/s at 40 °C, viscosity index 146, pour point -30 °C, flash point 235 °C, density 870 kg/m³.

Application

High-performance four-stroke motorcycle engines, air- or liquid-cooled, with a gearbox shared with the engine and a wet clutch.

Worth knowing

The subtitle of the Shell data sheet, “Synthetic Based 4 Stroke Motorcycle engine oil”, is easy to read as “synthetic”, but in the text of the same data sheet the composition is called “part synthetic”, that is, partly synthetic. That is why the catalogue lists AX7 as part-synthetic, in other words a semi-synthetic oil. The data sheet of Advance Ultra 15W-50 (SN/MA2), on the other hand, explicitly calls that oil 100 % synthetic, with a base derived from natural gas using PurePlus technology.

By the figures the two oils are close: 149 mm²/s at 40 °C in both, 19.2 against 20.5 mm²/s at 100 °C, viscosity index 146 against 160, and the same flash point of 235 °C. What separates them is the API grade: SM in AX7, SN in Ultra, while the third 15W-50 in the line, Advance Ultra 15W-50 SP MA2, has SP. For a motorcycle whose manual specifies API SN or SP, the SM grade of AX7 falls short. The AX7 data sheet also covers 10W-30 and 10W-40 with the same API SM and JASO MA2.
