Castrol Transmax Longlife 75W-90 is a fully synthetic gear oil. It is a premium product from Castrol.

Advantages:

Castrol Transmax Longlife 75W-90 offers the following advantages:

  • Fuel savings and reduced emissions due to balanced viscosity and friction characteristics
  • Excellent pumpability at low temperatures ensures optimal protection during startup under all conditions
  • Excellent thermal and oxidative stability provides a higher degree of cleanliness for the differential and final drives, allowing for extended change and service intervals
  • Optimal protection against wear and resistance to extreme pressures at all ambient temperatures and loads
  • High temperature reduction capability and excellent shear stability ensure final drive performance and extend the life of components

A brief discussion on gear oils:

Specifications of gear oils
Viscosity
The specifications used to evaluate the viscosity properties of gear oils is the SAE (Society of Automotive Engineers, USA) classification. This standard is used to classify oils into 4 winter grades, marked with a number and "W" (from English Winter), and 5 summer grades marked with a number.

Winter grades: 70W, 75W, 80W, 85W
Summer grades: 80, 85, 90, 140, 250
If only one grade is used for labeling, it means that it is a monograde oil (summer or winter). When a combination of summer and winter grades is used (e.g., 80W-90), it is a multigrade oil, or in other words, all-season. More often, unlike motor oils, manufacturers require monograde gear oils.

Performance categories
The classification used for labeling the performance category of gear oils is the API (American Petroleum Institute, USA) classification. The performance class designation consists of the letters "GL" (from English Gear Lubricant) and a number indicating the performance level, of which there are six.

Currently, the following four performance classes are used:
GL-3 - low-additive oils for manually shifted transmissions with medium loads
GL-4 - highly additive oils primarily intended for manually shifted transmissions and lightly loaded hypoid gears
GL-5 - oils intended for heavily loaded hypoid gears operating under the most challenging conditions, subjected to variable shock loads
GL-6 - oils for hypoid gears operating in extreme conditions. They are still used very rarely.

How to properly select gear oil?
The principles for selecting gear oil are similar to those for selecting motor oil.

1. The first principle in choosing gear oil is to follow the manufacturer's recommendations for motorcycles, as outlined in the manual for each vehicle. Only the transmission (vehicle) manufacturer can responsibly state which oil can be used. Practically no manufacturer recommends a specific oil brand (this contradicts competition laws in the European Union). Transmission manufacturers (of vehicles) recommend oils according to such performance specifications as API GL-4, API GL-5, and viscosity specifications such as SAE 75W, 80W-90.
2. For such recommended oils, the change intervals are then determined (usually 10,000 km or 1 year).
3. If you do not have the vehicle manual, ask the vehicle manufacturer (at the Czech headquarters of the importer). Remember, the vehicle manufacturer does not recommend a brand of oil, only performance and viscosity specifications.
