Which Engine Oil is Right for Your Used GMC Engine?

GMC engines are a great buy as they offer excellent payload and towing capacity. If this reason led you to buy a used GMC engine, you need to realize the importance of using the right type of engine oil in your GMC engine.

In late 2000, GMC came up with their own internal engine oil specification system and started using it in all their engines. This new engine oil quality was created specifically for GMC engines instead of using the API or ACEA oil quality standards which were broad and general specifications. This range of engine oil was named GM dexos and was launched to give GMC engines exactly the type of lubrication they need.

So, when you’re looking for a used engine for sale, also look for its engine oil requirements. In case you go for a used GMC engine, the following are the recommended engine oil types.

Recommended Engine Oil Types for GMC Engines 

GM dexos1™ First Generation

The first-generation GM dexos engine oil was introduced in 2009 after spending two years under development. It was the first one in the GM’s engine oil line-up. It was slowly picked up by GMC owners and used in most GMC gasoline engines by 2011. This number increased gradually. By 2015 almost all the GMC gasoline engines were using the GM dexos first gen engine oil.

In the USA, the dexos1 engine was recommended for all GMC engines over existing engine oil types of multiple viscosities of SAE 0W-20, 5W-20, 5W-30 and correspond to API SN (RC) and ILSAC GF-5 oil specifications.

GM Dexos1 Second Generation

The GM dexos1 second-generation engine oil type was introduced in late 2015 and came into use in 2017 in the USA. It was an updated version of the first-gen oil type and used for a broad range of GMC gasoline engines. It has higher standards and offers better performance levels for the rigors of demanding start-stop driving situations because of upgraded engine oil formulation.

The new generation of dexos engine oil works to improve durability by providing better wear protection, oil flow, and fuel efficiency. It’s also highly resistive to carbon deposits, oxidation, sludge, and corrosion. It also helps prevent mechanical issues associated with modern GDI (Gasoline Direct Injection) and TGDI (Turbocharged Gasoline Direct Injection) engines.
