Description

Castrol TRANSMAX Limited Slip Z 85W-90 is a gear oil from the TRANSMAX line for drive axles with limited-slip differentials. It is used mainly in ZF-built axles fitted to commercial and off-road vehicles.

The oil is rated API GL-5 and holds official ZF TE-ML 05C, ZF TE-ML 16E and ZF TE-ML 21C approvals. All three ZF classes are specifically for limited-slip differentials.

Typical figures: 16.2 mm²/s at 100 °C and 175 mm²/s at 40 °C, viscosity index 95, pour point -15 °C, flash point 210 °C, density 903 kg/m³.

Application

Axles with limited-slip differentials, above all ZF-built axles in commercial and off-road vehicles that require ZF TE-ML 05C, ZF TE-ML 16E or ZF TE-ML 21C.

Worth knowing

The letter after the ZF list number matters more here than the name of the line. Most TRANSMAX axle oils have the classes 05A and 21A, whereas this one has 05C and 21C, and in the TE-ML 05 list class 05C means, according to ZF, an oil with additives for limited-slip differentials. For axles with a limited-slip differential, API leaves the friction requirements to the axle maker; why LS oils contain friction modifiers, and why they are superfluous where they are not required, is explained in the article on GL-4 and GL-5 gear oil.

The words Limited Slip appear in the name of one more oil in the line, Limited Slip LL 75W-140. It also carries ZF TE-ML 05C and 21C, but has 16G instead of 16E, and in addition ZF TE-ML 18 and MB 235.61. The viscosity grade differs too: 75W-140 with 24.7 mm²/s at 100 °C, against 16.2 mm²/s for Z 85W-90, so identical words in the name do not make these oils interchangeable. Among the TRANSMAX oils in the catalogue, only Z 85W-90 has the ZF TE-ML 16E class.
