* Engine Condition: The ideal oil weight depends on factors like your engine's condition, climate, and how hard you drive it.
* Driving Conditions: High-performance engines, like yours, may require different oil weights depending on whether it's driven mostly for racing, daily driving, or a mix.
* Manufacturer Recommendations: The most reliable information comes from the engine manufacturer or the owner's manual.
Here's what I suggest:
1. Consult your ZZ4 engine manual: The manual will have specific oil weight recommendations for your engine.
2. Contact GM or a qualified mechanic: They can provide guidance based on your specific use case and engine conditions.
General Considerations:
* Thicker oil (higher viscosity) is better for hot climates or high-performance driving. It provides better protection at high temperatures and can handle higher pressures.
* Thinner oil (lower viscosity) is better for cold weather or when fuel economy is a priority. It flows more easily at low temperatures and reduces friction for better fuel efficiency.
Remember: Using the wrong oil weight can damage your engine. Always consult the manufacturer's recommendations or a qualified mechanic to ensure you use the best oil for your ZZ4 350 engine.
