Description

Motul GEAR 300 75W-90 is a fully synthetic gear oil built on the Ester Core ester base, with extreme-pressure additives. It is intended for gearboxes, transaxles, transfer boxes and hypoid axles in sports and high-performance road cars.

The oil is rated API GL-4 and API GL-5; the maker states that its performance exceeds the requirements of these categories. The data sheet lists no car-maker approvals.

Typical figures: kinematic viscosity 14.4 mm²/s at 100 °C, viscosity index 171, pour point -51 °C, flash point 206 °C. Available in 1 to 60 litres.

It is not intended for limited-slip differentials; for those the line offers a separate variant, Motul GEAR 300 LS 75W-90.

Application

Gearboxes, transaxles, transfer boxes and hypoid axles without a limited-slip differential in sports and high-performance cars where a 75W-90 GL-4 or GL-5 oil is suitable.

Worth knowing

At -51 °C, this oil’s pour point is the lowest of the five oils in the Gear line, yet it does not mark the limit of cold-weather use: SAE J306 checks the 75W winter grade by Brookfield viscosity, no higher than 150,000 mPa·s at -40 °C, and the data sheet has no such line. The article on the figures in an oil’s technical description covers why the pour point is so easy to misread. When hot, the oil is also the thinnest in the line: 14.4 mm²/s at 100 °C, closer to the lower limit of grade 90 (13.5 to 18.5 mm²/s). The data sheet recommends it for transmissions that should run better than they would on a grade 140 oil, and claims zero viscosity loss from shear.

Motul also has another 75W-90 with API GL-4 and GL-5, MOTYLGEAR 75W-90, from a separate line. It is thicker, at 18.1 mm²/s at 100 °C, has the same -51 °C pour point, and its data sheet additionally declares compliance with MIL-L-2105D.
