Description

Shell Spirax S3 G 80W-90 is a long-life mineral Spirax gear oil. It is intended for synchromesh manual gearboxes and moderately loaded axles in commercial vehicles, above all MAN vehicles and those with ZF units.

The oil is rated API GL-4 and holds the approvals MAN 341 Type E2, MAN 341 Type Z2 and ZF TE-ML 02B, ZF TE-ML 16A, ZF TE-ML 17A and ZF TE-ML 19A. The maker states an extended drain interval.

Typical figures: 15.3 mm²/s at 100 °C, 160.5 mm²/s at 40 °C, pour point -30 °C, flash point 215 °C, density 895 kg/m³.

Application

Synchromesh manual gearboxes and moderately loaded axles in commercial vehicles, above all MAN vehicles and those with ZF units.

Worth knowing

The extended change interval the data sheet mentions does not by itself fix the period for a ZF gearbox: that depends on the oil’s class in the TE-ML 02 list. From that list the oil has only ZF TE-ML 02B, for which ZF sets shorter periods than for 02L and 02E: for long-haul work 180,000 km or one year, against 360,000 km and 600,000 km for the other two classes. How a class is tied to an interval is explained in the article on what ZF TE-ML gear oil approvals mean.

Its neighbour in the range, Spirax S3 AM 80W-90, likewise has MAN 341 Type E2, MAN 341 Type Z2 and ZF TE-ML 02B, plus API GL-5 and the axle approval MAN 342 Type M2. Of the pair, only S3 G lists ZF TE-ML 16A, ZF TE-ML 17A and ZF TE-ML 19A; in the same lists S3 AM has 16C, 17H and 19B, and a unit is matched only by the letter given in its own documentation.
