Mobil Delvac Ultra Total Driveline 75W-90

Worth knowing

Mobil gives no figures for extended drain intervals; for a gearbox on the ZF TE-ML 02 list the oil class sets them. Of that list only ZF TE-ML 02B is recorded here, without 02L and 02E, so according to the ZF interval table a long-haul run means 180,000 km or a year, and off-road and quarry work means 20,000 km, 1000 engine hours or a year, whichever comes first.

What mainly separates it from Mobil Delvac 1 Gear Oil 75W-90 is the gearbox codes: ZF TE-ML 02B, MAN 341 Type Z2, Scania STO 1:1 G and API GL-4 are absent from that oil. That oil does have ZF TE-ML 16F, MAN 342 Type M2, Mack GO-J Plus, Volvo 97312 and MB 235.9, while SAE J2360, API GL-5 and ZF TE-ML 05A, 12L, 12N, 17B, 19C, 21A remain common to both. This oil’s page mentions MT-1 only in the line about use, not in the specification list; Delvac 1 Gear Oil lists it. The pour point is -48 °C for both, while the viscosity at 100 °C differs: 16.6 and 15 mm²/s. Brookfield viscosity at -40 °C here is 135,000 mPa·s.
