Description

Mobil Delvac 1 Transmission Fluid V50 75W-90 is a fully synthetic oil for the manual gearboxes of Volvo trucks. It is designed for heavy haulage, frequent power take-off use, severe winters and extended drain intervals.

The oil holds official Volvo 97315 and Volvo 97319 approvals. ExxonMobil recommends it where API GL-4 is specified; this is not a certification.

Typical figures: 17.8 mm²/s at 100 °C, viscosity index 172, pour point -42 °C.

The oil is intended only for manual and non-hypoid gearboxes; it is unsuitable for hypoid differentials and final drives that require GL-5.

Application

Manual gearboxes in Volvo trucks where a Volvo 97315 or 97319 oil is specified, including heavy haulage, frequent power take-off use, severe winters and extended drain intervals.

Worth knowing

The Volvo codes 97315 and 97319 set this oil apart from Mobil Delvac 1 Transmission Fluid V30 75W-80 with its Volvo 97307 and 97318, and the difference is tied to gearbox design. According to Volvo Trucks’ fluid descriptions for North America, the 75W-80 version with those codes is not approved for I-Shift with overdrive (ATO), which needs 75W-90; the latter suits all overdrive I-Shift and the most severe duties, while for normal and heavy duty in automated gearboxes Volvo also allows 75W-80. At 100 °C these two oils have 17.8 and 9.2 mm²/s. Volvo codes for gearboxes and axles are collected in the table of truck approvals.

The data sheet extends the restriction on hypoid gears in differentials and final drives, where API GL-5 or MIL-PRF-2105E is specified, to topping up as well as filling. For the rear axle it mentions pairing with Mobil Delvac synthetic gear oils. Volvo 97312, this make’s code for the drive axle, appears among the Mobil oils in the catalogue only in Mobil Delvac 1 Gear Oil 75W-90, whose data sheet in turn does not recommend it for the GL-4 level.
