Frequently Asked Questions (FAQs)

Q: How often should I change my car oil?

A: The ideal oil change interval depends on several factors, including your vehicle’s make and model, your driving habits, and the type of oil used. Consult your owner’s manual for specific recommendations, but generally, synthetic oils can often go longer (up to 10,000 miles) than conventional oils.

Q: What does the number and letter designation (e.g., 5W-30) mean?

A: The number before the “W” indicates the oil’s viscosity (thickness) in cold temperatures, while the number after the “W” indicates its viscosity at higher temperatures. A lower number means thinner oil, ideal for colder climates.

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

A: Conventional oil is refined from crude oil. Synthetic blend combines conventional and synthetic oils, offering a balance of cost and performance. Full synthetic oil is engineered for superior performance and protection, often lasting longer between changes.

Q: Can I mix different types of motor oil?

A: It’s generally not recommended to mix different types of motor oil (e.g., conventional and synthetic) unless explicitly stated by the manufacturer. Mixing can sometimes lead to compatibility issues.

Q: How do I choose the right viscosity for my car?

A: Check your owner’s manual for the recommended oil viscosity for your vehicle. This information is crucial for optimal engine performance and protection.

Q: What are the benefits of using full synthetic oil?

A: Full synthetic oils offer superior performance and protection compared to conventional oils, often including better cold-weather protection, reduced wear, extended drain intervals, and better overall engine cleanliness.

Q: What if my car uses a specific type of oil as recommended by the manufacturer?

A: Always prioritize the oil type recommended by your vehicle’s manufacturer. Using the wrong oil can void warranties or damage your engine.
