FAQ:
Q: How often should I change my oil in a high-mileage vehicle?
A: While manufacturers provide guidelines, high-mileage vehicles often benefit from more frequent oil changes. Consult your owner’s manual and consider more frequent changes, especially if you drive in harsh conditions.
Q: What does high mileage mean?
A: Generally, “high mileage” refers to vehicles with over 75,000 miles. However, the specific mileage at which an oil change strategy should change may depend on the specific vehicle.
Q: Can I mix different types of oil?
A: It’s generally not recommended to mix different types of oil (e.g., synthetic and conventional). Sticking to the same type of oil consistently is best.
Q: What is the significance of the oil viscosity (e.g., 5W-30)?
A: Viscosity refers to the oil’s thickness. The numbers indicate its performance at different temperatures. Choosing the correct viscosity is crucial for proper engine lubrication.
Q: What are the benefits of using full synthetic oil?
A: Full synthetic oils offer superior protection against wear and tear, better high and low-temperature performance, and often longer drain intervals.
Q: What if my high mileage car is already leaking oil?
A: If you’re already experiencing oil leaks, it’s best to consult a mechanic to diagnose the problem and find a proper repair. While some oils claim to help reduce leaks, they are not a fix for a significant mechanical problem. Using a stop leak additive might mask the issue temporarily, but a thorough inspection is crucial.
