## Questions & Answers

**Q: What is the mile usage?**
A: Thank you for contacting Castrol North America.

At a minimum, motor oil should be changed as recommended by your car owner’s manual or the oil life indicator for the type of service (normal or severe) that the vehicle is being operated under.  

When motor oil is in use in an engine, motor oil additives will break down as they perform their job.  This break down will continue over time and continued use, so it is important to change your oil to keep your engine protected.

Thank you again for contacting Castrol, we value your patronage!
