Published by Dustin Babich on

Dexos gen 3 is an upgrade to the previous gen 2 specification. The main difference between the two is that gen 3 has a higher level of performance and more advanced testing requirements.

The development of dexos gen 3 was necessary to keep pace with evolving engine technology and provide better engine protection. It includes tougher requirements for engine oil shear stability, improved oxidation control, and better deposit protection. In addition, gen 3 specifications require more sophisticated testing protocols to ensure that oils meet or exceed performance standards.

The upgrade to the latest specification is recommended for newer engines, and also provides an opportunity to switch to oils with a longer service life. Though the upgrade comes at a slightly higher cost, it is believed to be a valuable investment in engine protection.
