Castrol Transmax Longlife 75W-90 is a fully synthetic transmission 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 starting 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 wear protection and resistance to extreme pressures under all ambient temperatures and loads
  • High temperature reduction capability and excellent shear stability ensure the performance of the final drive and extend the lifespan of components

A brief discussion on transmission oils:

Transmission oil specifications
Viscosity
The Society of Automotive Engineers (SAE) specification is used to evaluate the viscosity properties of transmission oils. This standard is used for classifying oils into 4 winter grades, marked with a number and “W” (from English Winter), and 5 summer grades denoted by 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 means that it is a monograde oil (either summer or winter). When a combination of summer and winter grades is used (e.g., 80W-90), it refers to a multigrade oil or all-season oil. Unlike motor oils, manufacturers often require monograde transmission oils.

Performance categories
The API (American Petroleum Institute) classification is used to mark the performance categories of transmission 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 transmissions under medium load
GL-4 - highly additive oils primarily intended for manual transmissions and lightly loaded hypoid gears
GL-5 - oils designed for heavily loaded hypoid gears operating under the most severe conditions, exposed to variable shock loads
GL-6 - oils for hypoid gears operating in extreme conditions. They are still used very rarely.

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

1. The first rule when choosing transmission oil is to follow the manufacturer's recommendations, which are contained in the manual for each vehicle. Only the transmission manufacturer (of the vehicle) can responsibly indicate which oil can be used. Practically no manufacturer recommends a specific brand of oil (it goes against competition laws in the European Union). Transmission manufacturers (of cars) recommend oils according to the so-called performance specifications, e.g., API GL-4, API GL-5, and SAE viscosity specifications, e.g., 75W, 80W-90.
2. For such recommended oils, change intervals are then set (usually 10,000 km or 1 year).
3. If you do not have a manual for the vehicle, ask the manufacturer (at the Czech headquarters of the importer) of the vehicle. Remember, the vehicle manufacturer does not recommend a brand of oil, but only a performance and viscosity specification.
