The 2015 Chevy Silverado 2500HD with the 6.0-liter V8 uses Dexos1 Gen 2 certified engine oil, typically 5W-30, and it holds about 6 quarts with the filter. Use a GM OE filter or an equivalent that meets Dexos1 Gen 2 specifications.
Oil specification and capacity
The oil specification and capacity are key for proper lubrication and warranty coverage. For the 6.0L V8 in this model year, GM requires Dexos1 Gen 2 oil and an approximate capacity of 6 quarts (about 5.7 liters) with a new filter.
Key requirements
Below are the essential points to ensure you use the correct oil and filter.
- Oil specification: Dexos1 Gen 2 certified gasoline engine oil
- Viscosity: typically 5W-30 for this engine in most climates
- Oil type: synthetic blend or full synthetic, as long as it meets Dexos1 Gen 2
- Oil filter: GM OE or equivalent that meets Dexos1 Gen 2
- Oil capacity: approximately 6 quarts (5.7 liters) with filter
Using oils that do not meet Dexos1 Gen 2 may affect performance and warranty coverage.
Oil change intervals and maintenance tips
Oil-change timing for the 6.0L V8 depends on driving conditions. The following guidance covers typical scenarios and how to tailor it to your usage.
Guidelines for intervals and maintenance:
- Normal service interval: about 7,500 miles (12,000 km) or 12 months, whichever comes first, when using Dexos1 Gen 2 5W-30 with a synthetic blend or full synthetic
- Severe service or extreme conditions (towing, short trips, dusty roads, very hot or cold climates): change every 3,000–5,000 miles (5,000–8,000 km) or sooner
- Regularly check the oil level and top up with the same Dexos1 Gen 2 5W-30 if needed
Always refer to the owner’s manual or your dealer for precise intervals aligned with your vehicle’s configuration and local conditions.
Verification and practical tips
To ensure you’re using the correct oil, verify the specification on the oil bottle and cross-check with your owner’s manual. Dexos1 Gen 2 is the standard for GM gasoline engines since the early 2010s, and 5W-30 is the typical viscosity recommendation for the 6.0L V8 in the 2015 Silverado/Sierra 2500HD.
Summary
In short, the 2015 Chevy 2500HD with the 6.0L V8 requires Dexos1 Gen 2 certified engine oil, usually 5W-30, with a capacity of around 6 quarts including the filter. Use a GM OE filter or an equivalent that meets Dexos1 Gen 2, and follow the recommended change intervals based on driving conditions—about 7,500 miles under normal use, or more frequently in severe service. Always confirm specifics in your owner’s manual for your region and driving styles.
