Regardless of whether it is for cars, trucks & buses, motorcycles & ATVs, marine, construction machines, industry, agriculture & forestry or classic cars - which transmission oil is the right one primarily depends on which transmission needs to be lubricated. Due to the variety of different transmissions, there are also various transmission oils.

Both engine oils and transmission oils are used in vehicles, but the requirements for these oils are completely different. The reason for this is the different areas of use and the conditions in these places.
Continue readingDifferent transmissions or axles require different transmission oils. Therefore, the transmission oils are labeled with specifications from vehicle manufacturers and the American Petroleum Institute (API) so that the right oil can be found for the transmission or axles.
Continue readingThe transmission oil has various requirements that it must meet. The most important ones are:
- Lubricating metal parts that slide against each other
- Cooling the transmission
- Transmitting power from gears
- Protecting against corrosion
Transmission oils need to be changed much less often than engine oils. The reason for this is that engine oil needs to transport not only friction residues, but also combustion residues. The transmission oil, on the other hand, is only contaminated by tiny metal chips due to friction and therefore lasts longer.

This question is frequently asked – especially with gear oils featuring API GL-4 or API GL-5 specifications.
The background: In manual transmissions and industrial equipment, yellow metals such as brass, bronze, or other copper alloys are commonly used. Typical components include:
- Synchronizer rings in manual transmissions
- Bronze plain bearings and bushings
- Worm gears in industrial gear units
- Hydraulic pumps and valve components
- Compressors and turbines
