Description

Mobil 1 Racing 2T is a fully synthetic oil for two-stroke engines, mixed with the fuel. It is pre-diluted, so it blends more easily, and is designed for low exhaust smoke.

The oil is rated API TC, JASO FC and FD, ISO-L-EGC and ISO-L-EGD, as well as SAE Grade 1 and SAE Grade 2. The data sheet lists no equipment-maker approvals.

Typical figures: 12.7 mm²/s at 100 °C, 83 mm²/s at 40 °C, viscosity index 154, pour point -42 °C, sulphated ash 0.15 %. Applications: high-performance motorcycles, snowmobiles and chainsaws running lean mixtures.

Application

High-performance two-stroke motorcycles, snowmobiles and chainsaws running lean mixtures where API TC or JASO FD oil is required; the oil is mixed with the fuel.

Worth knowing

ExxonMobil states the same API TC, JASO FC and FD for the semi-synthetic Mobil Extra 2T as well. The two differ in their ISO classes: Extra 2T meets only ISO-L-EGD, and of this pair only Racing 2T also has ISO-L-EGC. The rest of the difference shows in the data-sheet figures: 12.7 against 8.8 mm²/s at 100 °C, a pour point of -42 °C against -24 °C, sulphated ash of 0.15 % against 0.06 %. Mobil Super 2T has JASO FB and ISO-L-EGB, so where the engine manual calls for FC or FD, it is no substitute for this oil.

The typical ash content of 0.15 % is within the limit that the JASO M345 standard sets for class FD: no more than 0.18 %. The data sheet gives no mixing ratio, so take it from the engine manual. What separates FC from FD, what the ISO-L-EGD mark means and why the ratio is as much a manufacturer’s requirement as the oil class, is explained in the article on two-stroke oil and its JASO and ISO classes.
