* Vehicle Condition: The best oil depends on your car's condition (mileage, driving habits, climate), and whether it has any engine modifications.
* Oil Viscosity: The correct viscosity (thickness) is crucial. Your owner's manual will specify the recommended viscosity grades (e.g., 10W-30, 5W-40).
* Oil Type: You need to choose between conventional, synthetic blend, or fully synthetic oil. Synthetic oils offer better performance in extreme conditions, but conventional oil is often suitable for older vehicles.
Here's what you need to do:
1. Check your owner's manual: It will provide the most accurate information about the recommended oil viscosity and type for your specific engine.
2. Consult a mechanic: A qualified mechanic can assess your car's condition and advise you on the best oil based on your needs.
3. Look for reputable brands: Choose a well-known brand of motor oil that meets the specifications in your owner's manual.
Remember: Using the wrong oil can damage your engine. Always prioritize the information in your owner's manual and seek professional advice when needed.
