Description

Liqui Moly Top Tec ATF 1950 is a single-purpose fluid for the modern Mercedes-Benz 9G-Tronic nine-speed automatic gearbox, types 725.0 and 725.1. The fluid is brown in colour.

It holds no official approval; according to the manufacturer, it meets the requirements of MB 236.17. The manufacturer lists no other applications.

Typical figures: 5.3 mm²/s at 100 °C, viscosity index 165, flash point 180 °C, pour point -54 °C. Available in 1 and 20 litre packs.

Application

The Mercedes-Benz 9G-Tronic nine-speed automatic gearbox (types 725.0 and 725.1), for which MB 236.17 fluid is specified.

Worth knowing

The order of the numbers in the line does not match the order of viscosity. The 1950 has 5.3 mm²/s at 100 °C, whereas the 1900 has 4.4 mm²/s; at 40 °C it is 24 and 19 mm²/s, and the data sheets give the Brookfield limiting viscosity at -40 °C as ≤15,000 and ≤10,000 mPa·s. They share no code either: MB 236.17 here, MB 236.15 there, and each of the two data sheets rules out mixing with oils of other specifications.

The catalogue contains no other Liqui Moly fluid under MB 236.17. The page MB 236.17 lists five fluids from three brands, and for none of them is this code an approval. In an early service bulletin for the USA and Canada, Mercedes-Benz assigns sheet 236.16 to the 725.0 gearbox; the 1950 list has no such number, and the data sheet itself requires you to follow the carmaker’s specifications. So when the vehicle documentation names 236.16 specifically, confirm the fluid from Mercedes-Benz data. Where to look for the entry in the sheet is explained in the article on universal ATF and the Mercedes-Benz list.
