The meaning of abbreviations in engine oil

03.06.2022 /

All oils have numbers and abbreviations, which often we don't know what they mean, and we can use what is not suitable for the car.

Engine oil is one of the most important fluids for the operation and long life of a car. Timely maintenance and oil awareness will keep your engine running and free from damage due to lack of oil.

There are different types of oils, you can find oils on the market. synthetics or minerals, depending on their application, but from there they all have numbers and abbreviations that often we do not know what they mean and we can use one that does not fit the car.

Many of us use multigrade oils because they meet SAE standards for both situations. They have the characteristics of a light oil for proper operation at very low temperatures and the characteristics of a heavy oil to maintain viscosity at high temperatures. This is achieved by adding additives to the oil that cause the viscosity to rise as the engine temperature rises, maintaining constant engine lubrication and protection,

That is why here we will help you to know the meaning of these abbreviations.

  • Meaning of SAE initials, Society of Automotive Engineering, are responsible for coding engine oils depending on their viscosity and engine capacity. lubricating oil perform its function depending on the temperature at which the engine will start.
  • The word "W", This abbreviation is for oils that are suitable for high temperatures. In other words, "w" indicates winter or winter and is the viscosity value at low temperatures.
  • Number after abbreviation. Example: SAE 30 from 10n 50 The number after the abbreviation indicates the type of oil at high temperature. This means that, based on the abbreviation 5W-40, this oil will be 5th low temperature and 40th high temperature, which means that it has low viscosity properties and the engine can be started at very low temperatures.

    • You can also find abbreviations such as API SG, which classifies oil quality for four-stroke engines, or "API TC", which classifies quality for two-stroke engines, and abbreviations. ISO-L-EGB/EGC/EGD is an international two-stroke engine oil specification.
