Complete Oil Specifications

Your 2025 Chevrolet Silverado 1500 with the 5.3L EcoTec3 V8 (L84) requires SAE 0W-20 full synthetic oil meeting GM’s dexos1 specification, per the owner’s manual.

Why dexos1 0W-20 Matters

GM’s dexos1 specification is engineered for high resistance to oxidation, viscosity breakdown, and volatility loss under sustained load — relevant for a full-size truck engine that regularly tows or hauls. The 0W-20 grade also supports the L84’s Dynamic Fuel Management cylinder-deactivation system, which depends on consistent oil pressure across the lifter oil-control valves.

Capacity & Filter

The 5.3L V8 holds 8.0 quarts (7.6 liters) with a new filter. GM’s TechLink bulletin lists the OEM filter as ACDelco PF63.

Service Interval

GM’s manual lists 7,500 miles (12,000 km) as the Normal Service point for checking engine oil level and Oil Life percentage, and notes the Oil Life indicator can trigger earlier under severe conditions (towing, dusty/off-road driving, frequent short trips, extreme temperatures) rather than following a separate fixed severe-service mileage.
