Description

Eni Rotra GL 80W-90 is a gear oil from the Rotra line for hypoid axles under heavy load and for the gearboxes, steering boxes, reduction units and power take-offs of heavy machinery. Its extreme-pressure film withstands shock loads, and its additives protect against rust and foaming.

The oil is rated API GL-5 and meets MIL-L-2105D; it holds no official carmaker approvals.

Typical figures: viscosity 134 mm²/s at 40 °C and 14.5 mm²/s at 100 °C, viscosity index 100, pour point -30 °C, flash point 210 °C, density 895 kg/m³ and low-temperature viscosity 125,000 mPa·s at -26 °C.

Application

Heavily loaded hypoid axles, plus conventional gearboxes, steering boxes, reduction units and power take-offs of heavy machinery such as farm and earth-moving equipment.

Worth knowing

The MIL-L-2105D mark in this oil’s list belongs to a military specification that was replaced by MIL-PRF-2105E back in 1995, and that in turn was cancelled in 2005 in favour of SAE J2360. Lorry and bus axles often call for J2360 specifically, and of the six Rotra 80W-90 oils only Rotra Truck Gear 80W-90 claims compliance with it. How military axle-oil specifications passed into the SAE standard is briefly described in the article on GL-5, MIL-L-2105D and SAE J2360.

Its closest neighbour in the line, by code list, is Rotra MP 80W-90. It has the same GL-5 and the same MIL-L-2105D statement, but with official MAN 342 Type M2 and ZF TE-ML 05A, 12E, 16B, 17B, 19B and 21A approvals added; it is also slightly thicker, 151 mm²/s against 134 mm²/s at 40 °C. Rotra GL 80W-90 has no axle-maker or gearbox-maker codes at all, so when the unit’s documentation names one of those codes, it is the MP that has it, not the GL.
