Important Considerations:
* Check your owner's manual: This is crucial. The manual will specify the exact viscosity (like 5W-30 or something else) and the type of oil (conventional, synthetic blend, or full synthetic) recommended by the manufacturer. Ignoring this could damage your engine.
* API Certification: Look for an API (American Petroleum Institute) certification mark on the oil bottle. This ensures the oil meets certain quality standards. The specific API designation may be mentioned in your owner's manual.
* Oil Type: While 5W-30 is a common recommendation, whether you need conventional, synthetic blend, or full synthetic will depend on your driving habits and climate. Synthetic blends offer a good balance of performance and cost. Full synthetics are best for extreme temperatures or high-performance driving, but are more expensive.
Do not just rely on this information. Find your owner's manual and follow its instructions precisely. If you can't find the manual, you can often find a digital copy online through the Chevrolet website or a reputable parts website.
