What a good truck gear oil protects
Wear starts with high torque and shocks: gear teeth pit and oxidised oil leaves deposits.
Threat
How the oil protects
Wear and pitting under load
Delvac 1 Gear Oil and Ultra Total Driveline protect against wear at high torque and against pitting.
High-temperature deposits
Delvac 1 Gear Oil and Mobilube HD resist oxidation and limit deposits.
Synchronizer wear
Transmission Fluid 75W-80 and V30 protect copper alloys, extending synchronizer life.
Drag at cold start
Delvac 1 Gear Oil, V30 and Mobilube 1 SHC stay fluid in frost; Delvac 1 ATF lubricates down to -54°C.
Water and corrosion in the axleMobilube HD protect against rust and corrosion, HD-N even with water in the oil.
When to change gearbox or axle oil? Test a sample
Analysis of oil from a gearbox, axle or final drive shows wear metals, water and viscosity change. The trend across samples separates normal operation from a warning sign. Order from OlejeSklep: gear oil analysis (gearbox, axle). How oil analysis works
Prefer to call?+48 71 359 34 62“Give me the truck model and the gearbox or axle type. I will choose a Mobil oil that meets the maker’s spec.”
Questions before you buy
Both are for axles that require API GL-5. Delvac 1 Gear Oil is a synthetic for longer drain intervals, and Mobilube HD has an HD-A Plus version for Mercedes-Benz axles.
Not always. Delvac 1 Gear Oil is not for API GL-4 uses, and V30 is not for hypoid gears. For gearbox and axle, use Delvac Ultra Total Driveline or Mobilube 1 SHC.
No. An automatic transmission needs an ATF, e.g. Mobil Delvac 1 ATF for Allison transmissions (TES-295).
Make, model, year and the gearbox and axle type, ideally with the VIN. The name of the current oil helps too.
The vehicle maker sets the interval. Sample analysis tells you most reliably when to change.
