What Type of Oil Should I Use in My GMC? A Model-by-Model Breakdown

At Kerbeck Buick GMC, one of the most common questions we hear from our customers is: “What kind of oil should I use in my GMC?” Choosing the right motor oil is essential to keeping your vehicle running smoothly, maintaining fuel efficiency, and ensuring longevity. GMC models come with specific recommendations straight from the manufacturer to optimize performance—let’s break it down by model.

Why Oil Type Matters

Motor oil lubricates your engine’s moving parts, reduces friction, disperses heat, and helps remove contaminants. The wrong oil can lead to poor performance, increased engine wear, and even void your warranty. Always consult your owner’s manual or speak with a certified technician if you’re unsure—but this guide is a great place to start.

What Does “Dexos” Mean?

GM introduced the dexos oil specification to standardize quality and performance. Oils labeled dexos1 Gen 3 (for gas engines) and dexosD (for diesel engines) meet the latest standards for emissions systems, fuel economy, and engine longevity. Always look for the dexos logo on the bottle to ensure you’re using the right formulation.
