Description

77 Lubricants ATF MBS is a fully synthetic fluid from the ATF line for Mercedes-Benz 7G-Tronic Plus (NAG 2+) seven-speed automatic gearboxes. The maker presents it as a fluid that helps to save fuel.

It holds no official approval; the maker states that it meets the requirements of MB 236.15, which the car maker prescribes for these gearboxes.

Typical data-sheet figures: kinematic viscosity 5.7 mm²/s at 100 °C and 27.1 mm²/s at 40 °C, viscosity index 162, pour point -48 °C, flash point above 201 °C, density 844 kg/m³.

Application

Mercedes-Benz 7G-Tronic Plus (NAG 2+) seven-speed automatic gearboxes for which an MB 236.15 fluid is prescribed.

Worth knowing

The data sheet figures hardly distinguish this fluid from ATF MBF: 27.1 mm²/s at 40 °C, 5.7 mm²/s at 100 °C and a -48 °C pour point for both, viscosity index 162 against 160, density 844 against 849 kg/m³. They differ mainly in the Mercedes-Benz sheet and the colour. MBS is blue and claimed for MB 236.15, MBF is red and claimed for MB 236.14, so what counts for the gearbox is the sheet number in the service documentation, not matching tables of figures. Why typical values are not a guarantee, and what the maker actually guarantees, is explained in the article on the oil data sheet.

The MB 236.15 page lists 10 fluids from six brands, and three of them hold an official Mercedes-Benz approval. MBS belongs to the rest: in its data sheet 236.15 appears after the word “exceeds”, that is, as a statement by the fluid’s maker.
