Most 2010 GMC models use 5W-30 engine oil that meets GM's Dexos1 specification, but the exact grade and specification can vary by model and engine. Always verify with the owner's manual or the under-hood label.
Oil requirements by engine type
The exact oil you should use depends on whether your GMC uses a gasoline engine or a Duramax diesel. Gasoline engines in most 2010 GMC vehicles commonly require 5W-30, meeting Dexos1 Gen 1. Diesel Duramax engines require a diesel-grade oil that meets the appropriate API specification and GM requirements. Always confirm for your specific vehicle using the manual or VIN lookup.
Gasoline engines: common baseline
For most 2010 GMC gasoline engines (for example 4.3L V6, many 5.3L and 6.0L V8s), the factory recommendation is 5W-30 oil that meets Dexos1 Gen 1. You can choose a synthetic or synthetic-blend oil as long as it carries the Dexos1 specification.
- Viscosity: 5W-30 is the typical grade.
- Specification: Dexos1 Gen 1 (GM-approved).
- Oil type: synthetic-blend or full synthetic within Dexos1.
A note: some engines or climates may require variations; check the manual for your exact model.
Diesel engines (Duramax) in 2010 GMC
Some 2010 GMC models offer a Duramax diesel option. These require diesel engine oil meeting the appropriate API specification for diesel engines and GM’s guidance for Duramax. This is not a Dexos gasoline spec, and viscosity recommendations can differ from gasoline engines. Always refer to your owner's manual for the exact oil spec and viscosity for the Duramax engine in your truck or SUV.
How to confirm the exact oil for your vehicle
To ensure you use the correct oil for your specific 2010 GMC model, follow these steps:
- Check the owner's manual for the exact viscosity and specification (Dexos1 Gen 1, Dexos1 Gen 2, or diesel GM spec).
- Look under the hood for an oil-cap label or engine sticker that lists the recommended oil grade and spec.
- If the label is unclear, use your VIN to pull the official GM-recommended oil from a dealership or GM's online resources.
- If you have a Duramax diesel, follow the diesel oil specification in the manual and avoid using gasoline engine oil.
These steps help ensure you use the correct oil and preserve warranty coverage and engine longevity.
Maintenance tips for 2010 GMC oil changes
- Use a high-quality synthetic or synthetic-blend oil that meets the specified Dexos1 (or diesel GM specification) and viscosity for your engine. Regularly check the oil level and change interval as recommended by GM, typically every 5,000–7,500 miles for synthetic blends, or sooner under severe driving conditions.
- Use the correct oil filter as specified by GM for your engine to maintain proper filtration and performance.
Summary
The correct oil for a 2010 GMC varies by engine: gasoline engines generally use 5W-30 Dexos1 oil, while Duramax diesel variants use diesel-engine oil per the diesel specification. Always verify with the owner's manual or dealer resources for your exact model and VIN to ensure the right oil and maintenance interval.
What is the best oil for a 5.3 L V8?
Most recent Silverado 1500 models with the 5.3L V8 or 6.2L V8 engines typically use SAE 0W-20 full synthetic motor oil.
Can you run 5W-30 in a 2010 Chevy Silverado?
2007–2013 Silverado 1500 (GMT900)
Recommended oil: SAE 5W-30 (commonly synthetic blend or full synthetic). During this era, GM increasingly emphasized synthetics for longer-lasting protection and better cold-weather performance.
Can I put 5W-30 in my GMC Sierra?
The GMC Sierra 1500 oil type depends on the kind of engine you have. For a gasoline engine, we recommend SAE 5W-30 Dexos1 full synthetic oil. If you want protection for really low temperatures, consider 0W-30 oil. If you've got a Duramax turbo diesel engine, use SAE 0W-20 DexosD diesel engine oil.
