How often should you get an oil change for an 2014 GMC Sierra 3500HD?

• Follow the owner’s manual and oil life monitoring system for the most accurate interval tailored to your vehicle.
• For heavy use—frequent towing, hauling, or stop-and-go driving—service every 5,000 miles or every 6 months is recommended.
• For routine highway driving, many modern engines and synthetic oils allow 7,500 miles between services, but confirm via the owner’s manual.
• Regular dealer maintenance helps preserve warranty eligibility and creates a verifiable service record that supports resale value.

What type of oil does an 2014 GMC Sierra 3500HD take?

• Most 6.0L GM V8 engines perform best with full synthetic SAE 5W-30 meeting GM specifications; using the correct grade helps control viscosity under heavy load and temperature.
• Flex-fuel capability does not change the need for high-quality synthetic oil; synthetic resists breakdown from frequent towing and high operating temperatures.
• We use OEM-grade oils and filters and can confirm the exact spec for your vehicle by VIN—ensuring compatibility with warranty requirements.
• If your engine requires a specific GM specification (e.g., dexos), our certified technicians follow manufacturer guidance to protect engine longevity and warranty coverage.

How much oil does an 2014 GMC Sierra 3500HD need?

• Approximate capacity for a 6.0L V8 with filter change is about 7.6–8.0 quarts; the exact amount can vary slightly with filter and engine configuration.
• We measure and fill to the precise factory specification during service to avoid under- or overfilling.
• Our technicians document the service, dispose of used oil responsibly, and provide records that support warranty requirements and resale value.
