Frequently Asked Questions (FAQs)

Q: How often should I change my car’s motor oil?

A: The recommended oil change interval varies depending on the vehicle, driving conditions, and the type of oil used. Consult your owner’s manual for the manufacturer’s recommendations. Generally, synthetic oils can often go longer between changes than conventional oils.

Q: What does the number and letter combination (e.g., 10W-30) on motor oil mean?

A: This refers to the oil’s viscosity grade. The “W” stands for “winter,” and the numbers indicate the oil’s performance at low and high temperatures. For instance, 10W-30 means it flows well in cold temperatures (10W) and maintains its viscosity at high temperatures (30).

Q: What’s the difference between conventional, synthetic blend, and full synthetic motor oil?

A: Conventional oil is refined from crude oil. Synthetic blend oil is a mix of conventional and synthetic oils. Full synthetic oil is entirely manufactured, offering superior performance and protection.

Q: Can I mix different types of motor oil?

A: It’s generally not recommended to mix different types of motor oil (conventional, synthetic blend, and full synthetic) unless specifically stated in the respective products’ instructions. Mixing can sometimes lead to decreased performance or compatibility issues. Sticking to the same type is best.

Q: What is the importance of API certifications on motor oil?

A: The American Petroleum Institute (API) provides certifications that indicate an oil’s quality and performance. Look for the API certification symbol on the oil container to ensure it meets certain standards. These ensure the oil meets basic performance standards.

Q: My car’s owner’s manual recommends a specific oil viscosity. Can I use something else?

A: No, it’s crucial to use the viscosity recommended by your vehicle’s manufacturer. Using a different viscosity can harm your engine. Always consult your owner’s manual for specific recommendations.

Q: How can I choose the best car motor oil for my vehicle?

A: Refer to your vehicle’s owner’s manual for recommended oil type, viscosity, and specifications. Consider your driving conditions (city vs. highway) and the age and mileage of your vehicle when making your selection. If you’re unsure, consult a qualified mechanic for their advice.
