Description

77 Lubricants Autogear Oil SYN LS 75W-90 is a synthetic API GL-5 gear oil for drive axles. Its friction modifier is designed for limited-slip (LS) differentials: according to the maker, it reduces vibration and clutch chatter while the locking mechanism is at work.

It holds no official approvals; the maker states that it meets the requirements of Ford M2C192-A, ZF TE-ML 05C, 16G and 21C, Scania STO 1:0 and STO 1:1 G and Mack GO-J. Its list of specifications also includes SAE J2360 and MIL-PRF-2105E.

Typical figures: kinematic viscosity 15.7 mm²/s at 100 °C, viscosity index 160, pour point -42 °C, flash point above 201 °C.

Application

Drive axles with open and limited-slip (LS) differentials in cars, SUVs, vans, light trucks and off-road machinery.

Worth knowing

The maker’s data sheet promises that this single oil will serve both the rear axle and a manual gearbox, synchronised or not. Yet API GL-4 is not in the specification list, only GL-5 with the LS marking, and from Scania, which keeps axle and gearbox oils separate, it claims both the gearbox code STO 1:1 G and the axle code STO 1:0. For a car gearbox, the deciding factor is its documentation (GL-4 or the carmaker’s own code), not the data sheet’s general promise; why an axle with a limited-slip differential needs friction modifiers and what the sulphur-phosphorus additives of GL-5 do to synchronisers is explained in the article on GL-4, GL-5 and LS oils.

The nearest by name, SYN 75W-90, matches it only in part: they share GL-5, MIL-PRF-2105E, SAE J2360, Mack GO-J and both Scania codes. Of the two, only this oil has Ford WSL-M2C192-A and ZF TE-ML classes 05C, 16G and 21C, while API GL-4 and MT-1, MAN 341 Type Z2, MAN 342 Type M3, Volvo 97312 and ZF TE-ML 05A, 16B and 21A are claimed only for SYN 75W-90. SYN HD 75W-90 has none of the four codes that set SYN LS apart.
