FAQ:
Q: What does 5W-40 mean?

Q: Can I mix different brands of 5W-40 synthetic oil?
A: It’s generally not recommended to mix different brands or types of oil unless they are explicitly stated as compatible. Sticking to the same oil type ensures consistent performance and protection.
Q: What are the benefits of using synthetic oil?
A: Synthetic oils offer superior protection against wear, better high and low-temperature performance, longer service life, and improved fuel economy compared to conventional oils.
Q: What if my vehicle’s manual recommends a different viscosity grade?
A: Always follow the viscosity grade recommended in your vehicle’s owner’s manual. Using a different grade could negatively impact your engine’s performance and longevity.
Q: Are there any environmental considerations when choosing motor oil?
A: Many manufacturers are now producing oils with reduced environmental impact, using renewable materials and focusing on lower emissions. Look for oils with certifications or claims supporting environmental responsibility.
