Description

Shell Advance Ultra 2T is a synthetic low-smoke oil from the Advance line for powerful two-stroke motorcycle engines, racing engines included, and for snowmobiles operating down to -40 °C. It is based on polyisobutylene and Shell XHVI synthetic components; the oil already contains a hydrocarbon solvent, so it is self-mixing and suits separate oil injection systems.

The oil is rated JASO FD and API TC; it meets the requirements of ISO-L-EGD without an official approval.

Typical viscosity is 7.3 mm²/s at 100 °C. The data sheet gives pour and flash points as limits: pour point at most -48 °C, flash point at least 70 °C.

Not for outboard boat engines: the maker offers its Nautilus oils for those.

Application

Powerful air- or liquid-cooled two-stroke motorcycle engines, racing ones included, and snowmobiles down to -40 °C; separate oil injection systems. Not for outboard boat engines.

Worth knowing

Among the two-stroke Advance oils in the catalogue, only this one has JASO class FD, and JASO itself describes FD as an improved FC. The practical upshot: by grade, Ultra 2T is also suitable for an engine whose manual specifies FB or FC, whereas Advance SX 2 with FB and VSX 2 with FC do not meet an FD requirement. The API TC code beside them adds little: ASTM withdrew that specification without a replacement, so FD and ISO-L-EGD remain the benchmark.

In cold performance, Ultra 2T differs from the other two: its data sheet gives the pour point of -48 °C as a limit marked “maximum”, whereas VSX 2 has the same kind of limit at -20 °C and SX 2 has a typical value of -20 °C. What FD, ISO-L-EGD and API TC mean on a two-stroke can is explained in the article on two-stroke oil grades.
