Description

Eni Rotra 80W-90 is a mineral gear oil from the Rotra line for moderately loaded gear trains without hypoid gearing, including the transaxles of front-wheel-drive cars with a transverse engine. Its anti-wear additive does not corrode steel or copper.

The oil is rated API GL-3; it holds no official carmaker approvals.

Typical figures: kinematic viscosity 14.5 mm²/s at 100 °C, viscosity index 100, pour point -30 °C, flash point 250 °C, density 895 kg/m³ and low-temperature viscosity 130,000 mPa·s at -26 °C.

Application

Transaxles without hypoid gears (for example in front-wheel-drive cars with a transverse engine) and other moderately loaded gear trains for which API GL-3 is specified.

Worth knowing

Six Rotra oils share the 80W-90 grade, with different API classes: this one is GL-3, Rotra HY 80W-90 is GL-4, Rotra GL, MP and MP/S are GL-5, and Rotra Truck Gear 80W-90 claims GL-4, GL-5 and MT-1 at once. A shared SAE marking does not make these cans interchangeable, since the API classes are meant for different units, and this oil carries no carmaker or component-maker codes. If the unit’s documentation calls for GL-4, the oils with that class in the same viscosity grade are Rotra HY 80W-90 and Truck Gear 80W-90; a hypoid axle that calls for GL-5 needs one of the GL-5 oils.

Rotra 85W-140 carries the same GL-3, but its winter grade is different: for 85W the SAE J306 standard sets the limit of 150,000 mPa·s at -12 °C, not at -26 °C, and its pour point is -15 °C against -30 °C for the 80W-90. Rotra 80W-90 itself measures 130,000 mPa·s at -26 °C, which is within the limit of the 80W grade. The GL categories of API 1560, GL-3 among them, and all grades’ winter limits are summarised in the article on GL categories and the SAE J306 table.
