What is the Dexos1 Gen 2 standard for AMSOIL motor oil?
1. The reason for the development of Dexos® motor oil technology
Nowadays, manufacturers tend to downsize engines to create more compact and attractive vehicles. Additionally, cars are increasingly equipped with features such as direct fuel injection and turbocharging to optimize fuel consumption.
However, these new, lightweight engines tend to run hotter and operate under more pressure, necessitating stronger protection. Therefore, the need arose to develop a new type of oil to address these challenges, which is why Dexos® technology was created, marking a new turning point in the production of gasoline engine oils.

2.1 The emergence of Dexos1 Gen 1
In 2010, General Motors (GM) first launched the Dexos1 oil technology to better care for vehicle engines, surpassing all types of oils available at that time.

- No low-quality particles in the oil, using only high-quality lubricant components.
- Dexos1 Gen 1 is made from either fully synthetic or semi-synthetic base oils.
- Oxidation resistance extends oil change intervals up to 20,000 km.
- It burns faster and heats up more effectively than other oils on the market due to its low viscosity.
