Vehicle manufacturers often have different regulations in place when it comes to maintaining their vehicles. Of course, you could choose to go against these regulations, but you might void the warranty as a result. General Motors (GM) has put into effect a new requirement regarding the type of oil you can put in your vehicle. It’s important to know what this requirement is if you change your own oil on your vehicle, but you should also ensure the auto shop you take your vehicle to knows about it as well. Here are the highlights of GM’s new oil requirement.

GM’s New Oil Requirement

Effective March 31, 2021, GM has switched their requirement from using 5-20 oil in their vehicles down to 0-20 full synthetic. This requirement change comes as a result of testing at the GM power plant, and they came up with a ruling that they want to put 0-20 oil into certain vehicles to get better fuel economy. Their results also show that 0-20 oil is better for the engines of those specific vehicles. Making a change of this nature usually doesn’t happen overnight and is the result of rigorous studies and testing.
