FAQ:

Q: What does 5W-20 mean?
A: 5W-20 refers to the oil’s viscosity grade. The “5W” indicates its performance in cold temperatures (lower the number, better cold-weather performance), and the “20” signifies its performance at higher temperatures.

Q: How often should I change my 5W-20 oil?
A: Consult your vehicle’s owner’s manual for the recommended oil change interval. It typically ranges from 5,000 to 10,000 miles, but synthetic oils often allow for longer intervals.

Q: Can I use a different viscosity oil than recommended?
A: No, using a different viscosity oil than recommended can negatively impact your engine’s performance and longevity. Always follow the manufacturer’s recommendations.

Q: What are the benefits of using synthetic oil?
A: Synthetic oils generally offer better performance at both high and low temperatures, improved wear protection, and longer drain intervals compared to conventional oils.

Q: What is ILSAC GF-6A?
A: ILSAC GF-6A is an industry standard that specifies performance requirements for motor oils. Oils meeting this standard are designed for modern engines and provide protection against wear, deposits, and other issues.

Q: What are the differences between API SP and SN?
A: Both are API (American Petroleum Institute) specifications. API SP is the latest specification and offers improved protection compared to API SN. Many modern oils meet both specifications.

Q: What should I do if I’m unsure which oil to choose?
A: Consult your vehicle’s owner’s manual or a qualified mechanic. They can provide specific recommendations based on your vehicle’s needs.
