Published by Dustin Babich on

Dexos oil is a general motors (gm) licensed motor oil, while non-dexos oil is any oil that isn’t gm licensed. Motor oil is a crucial factor in keeping vehicles running smoothly.

Additionally, it is important to keep in mind that using the wrong type of oil could lead to potential issues with a vehicle’s performance and longevity.

Understanding Dexos And Non-Dexos Oils

Dexos and non-dexos oils are both used as engine oil in vehicles. Dexos oil is a certified synthetic blend that is formulated by general motors. It has gone through a series of rigorous tests and is often recommended for certain gm vehicles.

Non-dexos oil, on the other hand, is any oil that does not meet the dexos specification. The main differences between the two oils are their composition, performance, and price. Dexos oil provides better fuel efficiency, cleaner engine components, and longer engine life.
