Description

Shell Spirax S2 G 80W-90 is a Spirax gear oil with moderate extreme-pressure performance. It is intended for synchromesh manual gearboxes in trucks and off-road machinery and for moderately loaded rear axles in some light commercial vehicles, cars and motorcycles.

The oil is rated API GL-4. No vehicle-maker approvals are listed for it.

Typical figures: 14.7 mm²/s at 100 °C, 146 mm²/s at 40 °C, viscosity index 100, pour point -27 °C, flash point 175 °C, density 900 kg/m³.

It is not suitable for heavily loaded hypoid axles in trucks.

Application

Synchromesh manual gearboxes in on- and off-road commercial vehicles, and moderately loaded rear axles in some light commercial vehicles, cars and motorcycles.

Worth knowing

If a truck’s manual gearbox specifies not only an API category but also the code MAN 341 Type Z2 or ZF TE-ML 02B, you will not find it on this oil’s list, which has GL-4 alone. Among Spirax oils of the same viscosity, these approvals together with GL-4 are held by S3 AM 80W-90 and Spirax S3 G 80W-90, and S3 G adds MAN 341 Type E2 and ZF TE-ML 16A, 17A and 19A. The S3 G data sheet also gives its own figures: 15.3 mm²/s at 100 °C, pour point -30 °C, flash point 215 °C.

With S2 A 80W-90 the picture is the reverse: viscosity at 40 and 100 °C, viscosity index, pour and flash points are identical in the data sheets of the two oils, but the category is different, GL-5. The article on GL-4 and GL-5 in the gearbox and the axle covers when GL-5 can go into a gearbox that calls for GL-4 and when it cannot. The Shell data sheet also mentions S2 G’s earlier name: Spirax G 80W-90.
