- Viscosity: 5W-30 is the standard recommendation for this engine in most climates.
- Oil type/standards: Conventional, synthetic blend, or full synthetic oil that meets API SM (or newer) and GM 6094M specification.
- Capacity: Approximately 6 quarts with a filter; exact amount can vary slightly with filter size.
With these specifications in mind, select a reputable brand and type that clearly lists API SM or newer and GM 6094M on the label. Always confirm the exact capacity for your specific filter choice.
Choosing the right oil for climate and driving conditions
Synthetic vs. conventional options
For everyday driving in moderate climates, a conventional 5W-30 is usually sufficient. If you operate in extreme heat, regularly tow heavy loads, or want maximum protection for higher-mileage engines, a synthetic blend or full synthetic 5W-30 can provide better longevity and stability.
Enviroment and mileage considerations
Older engines or those with higher mileage may benefit from a synthetic-blend option, which offers extra protection against wear and oil breakdown. Regardless of the choice, ensure the oil meets API SM or newer and GM 6094M standards.
How to perform an oil change and verify you’ve got the right oil
During an oil change, drain the old oil completely, replace the oil filter, and refill with the recommended 5W-30 oil up to the vehicle’s specified capacity (about 6 quarts). After adding oil, run the engine briefly, then recheck the level and top off if needed. Always double-check the oil cap and owner’s manual for the exact spec and capacity.
