Description

Mobil Extra 2T is a part-synthetic, low-smoke oil for high-output two-stroke engines in motorcycles, snowmobiles and chainsaws. It comes pre-diluted, so it mixes with fuel more easily.

The oil meets JASO FC and FD, API TC and ISO-L-EGD; the record lists no official equipment-maker approvals.

Sulphated ash 0.06 %, 8.8 mm²/s at 100 °C, viscosity index 135, pour point -24 °C, flash point 110 °C.

Application

High-output two-stroke engines in motorcycles, snowmobiles and chainsaws where the oil is mixed with the fuel.

Worth knowing

Of the three Mobil two-stroke oils in the catalogue, two share JASO FC, FD and API TC: this semi-synthetic and Mobil 1 Racing 2T, which adds ISO-L-EGC to ISO-L-EGD. The third, Mobil Super 2T, is rated for the lower JASO FB and ISO-L-EGB, so it does not meet a manual’s FC, FD or EGD requirement. Substitution by class works the other way: the JASO standard calls FD an improved FC, and an FD oil suits an engine that needs only FB.

Its data sheet also sets it apart from Super 2T: viscosity at 100 °C is almost the same, 8.8 and 8.7 mm²/s, but the viscosity index is 135 against 110 and the pour point -24 °C against -12 °C. ExxonMobil gives all four codes as “meets or exceeds the requirements”, and the typical figures, the data sheet warns, are not a specification. Nor is the JASO box an approval: the supplier lists the oil itself, so the class on the can is checked by its nine-character code in that list. The article on two-stroke oil and the JASO classes shows how to verify a JASO code and how FC differs from FD.
