Description

Eni Rotra MP/S 80W-90 is a gear oil from the Rotra line for the hypoid gears of limited-slip differentials and for axles whose brakes or clutches run in oil. A friction modifier prevents judder and stick-slip in the clutch packs.

The oil is rated API GL-5. It holds no official approvals; according to its maker, it meets the requirements of ZF TE-ML 05C, ZF TE-ML 12C, ZF TE-ML 16E and ZF TE-ML 21C.

Typical figures: viscosity 124.1 mm²/s at 40 °C and 13.9 mm²/s at 100 °C, viscosity index 105, pour point -33 °C, flash point 215 °C, density 901 kg/m³ and low-temperature viscosity 135,000 mPa·s at -26 °C.

Application

Hypoid gears of limited-slip differentials and axles with oil-immersed brakes or clutches, such as tractor axles.

Worth knowing

What sets this oil apart from Rotra MP 80W-90 is not only the slash and the letter S in the name. The two share four ZF list numbers, 05, 12, 16 and 21, but the MP holds classes 05A, 12E, 16B and 21A there, while the MP/S has 05C, 12C, 16E and 21C. In list TE-ML 05, which concerns the axles of construction machinery, class 05C is reserved for oils with additives for limited-slip differentials, and 05A for an ordinary gear oil. So the MP’s official ZF approvals cover other classes, and no other Rotra 80W-90 claims a C class; here it appears as compliance on Eni’s word alone, without approval. The system in which the list number means the unit and the letter means the oil class is described in the article on ZF TE-ML codes.

According to its data sheet, the MP/S is also thinner: 13.9 mm²/s at 100 °C and 124.1 mm²/s at 40 °C against 15.5 and 151 mm²/s for the MP, and its pour point is -33 °C against -30 °C. Other oils with ZF TE-ML 05C are collected on a separate catalogue page.
