Eni Rotra MP DB 85W-90

Worth knowing

The specifications section of the Eni data sheet has only two lines, API GL-5 and MIL-L-2105D. Daimler Truck is mentioned elsewhere, among the product’s benefits: according to the maker, the oil suits applications where Daimler Truck requires a particular code of its specifications, but no such code appears in the specification list. This is Eni’s statement of suitability; the data sheet does not show whether the oil is on the approved-oil list Daimler Truck keeps for its lorries. Where to look for such entries is explained in the article on checking an oil approval.

If an axle calls for ZF TE-ML 05A, ZF TE-ML 16B or MAN 342 Type M2, Rotra MP DB 85W-90 does not have these codes. In the line, all three are approved for Rotra MP 80W-90, and ZF TE-ML 05A also for Rotra MP 85W-140, but those are other SAE grades, usable only where the manual allows such a viscosity. Rotra GL 80W-90 has the same GL-5 and MIL-L-2105D, but its winter grade is 80W. The data-sheet Brookfield viscosity, 130,000 mPa·s at -12 °C, is within the 85W limit, which SAE J306 sets at 150,000 mPa·s at the same temperature.
