Advantages:

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

Fuel savings and reduced emissions due to balanced viscosity and friction characteristics
Excellent pumpability at low temperatures ensures optimal protection during startup in 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 wear protection and resistance to extreme pressures under all ambient temperatures and loads
High ability to reduce temperature and excellent shear stability ensure the performance of the final drive and extend the lifespan of components

Brief discussion on gear oils:

Specifications for gear oils
Viscosity
To evaluate the viscosity properties of gear oils, the SAE (Society of Automotive Engineers, USA) specification is used. This standard is employed 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 in the designation, it indicates a monograde oil (either summer or winter). When a combination of summer and winter grades is used (e.g., 80W-90), it is a multigrade oil or all-season oil. Unlike motor oils, manufacturers often require monograde gear oils.

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

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

How to correctly choose gear oil?
When selecting gear oil, similar principles apply as when choosing motor oil.

1. The first rule when selecting gear oil is to follow the manufacturer's instructions for the motorcycle, contained in the manual for each vehicle. Only the gearbox manufacturer (of the vehicle) can responsibly state which oil can be used. Practically no manufacturer recommends a specific brand of oil (this contradicts competition laws in the European Union). Gearbox manufacturers (automobiles) recommend oils based on performance specifications, such as API GL-4, API GL-5, and viscosity specifications, such as 75W, 80W-90.
2. For these recommended oils, the change intervals are then specified (usually 10,000 km or 1 year).
3. If you do not have the vehicle manual, consult with the manufacturer (at the Czech importer headquarters) of the vehicle. Remember, the vehicle manufacturer does not recommend an oil brand, only the performance and viscosity specification.
