FAQS on passenger car engine oil

Q: How do I find the right engine oil for my car?

A: Check your car’s owner manual for the manufacturer’s recommended viscosity grade (e.g., 5W-30) and API certification. You can also use online tools from oil brands by entering your vehicle’s make, model, and year. Always match the oil type (conventional, synthetic, or blend) to your driving conditions.

Q: Why is viscosity important when selecting passenger car engine oil?

A: Viscosity determines how well the oil flows in different temperatures. Using the wrong viscosity can reduce engine efficiency or cause damage. Follow the manual’s guidelines to ensure optimal performance in both hot and cold climates.

Q: Can I use any engine oil labeled for passenger cars?

A: No—only use oil that meets your car’s specific API and OEM standards. Using incompatible oil may void warranties or harm engine components. Look for certifications like API SN or SP on the label to ensure compatibility.

Q: How often should I check or change my car’s engine oil?

A: Most modern cars require oil changes every 5,000–7,500 miles, but check your manual for exact intervals. Regularly monitor oil levels monthly and top up if low. Severe driving conditions (e.g., towing) may require more frequent changes.

Q: What happens if I mix different brands of passenger car engine oil?

A: Mixing brands is generally safe if they share the same viscosity and certifications. However, frequent mixing is not ideal, as additives may vary. For consistency, stick to one trusted brand unless emergency top-ups are needed.
