The 2015 Chevy Silverado 2500HD with the 6.0L V8 uses Dexos1 Gen 2 5W-30 motor oil, and it typically holds about 6 quarts with a filter.
In practice, choose a high-quality oil that meets Dexos1 Gen 2 specifications. Most owners opt for a full synthetic or synthetic-blend 5W-30, and it’s important to verify the Dexos1 Gen 2 approval on the label. Always refer to the owner's manual and the vehicle’s Oil Life Monitor for precise change intervals and capacity guidance.
Oil specification
To ensure proper protection and warranty coverage, use an oil that carries the Dexos1 Gen 2 certification and has a 5W-30 viscosity. The truck’s oil capacity is modest, but using the correct specification is crucial for the 6.0L V8’s performance and longevity.
Below are the common options that meet the Dexos1 Gen 2 spec and the expected viscosity. Note that using oils without Dexos1 Gen 2 approval can impact engine protection and warranty.
- Dexos1 Gen 2 5W-30 full synthetic motor oil
- Dexos1 Gen 2 5W-30 synthetic-blend motor oil
Whichever option you choose, ensure it explicitly states Dexos1 Gen 2 approval and 5W-30 viscosity on the bottle.
Capacity and maintenance intervals
Understanding capacity and when to change the oil helps keep the 6.0L V8 running smoothly. The engine is designed around Dexos1 Gen 2 5W-30 oil and a typical change cadence that reflects modern synthetic formulations.
- Engine oil capacity (with filter): about 6 quarts
- Recommended oil-change interval: under normal conditions,GM’s guidance with synthetic Dexos1 Gen 2 5W-30 often targets around 7,500 miles or 12 months, whichever comes first; in severe or towing-heavy use, consider 5,000–7,500 miles or sooner based on the Oil Life Monitor
- Practical tips: use a high-quality oil filter (OEM or equivalent) and follow the Oil Life Monitor’s alert for service timing
Always double-check your specific vehicle’s manual and keep an eye on the Oil Life Monitor, as driving conditions can shorten or extend intervals.
Summary
The 2015 Chevy Silverado 2500HD with the 6.0L V8 calls for Dexos1 Gen 2 5W-30 motor oil, typically about 6 quarts with a filter. Opt for a full synthetic or synthetic-blend that carries the Dexos1 Gen 2 approval, and follow the vehicle’s Oil Life Monitor to determine exact change intervals. When in doubt, consult the owner's manual or a Chevrolet service professional for your VIN-specific guidance.
