Practical Buying Advice:
The best oil for your high-mileage car depends on several factors: your vehicle’s age, mileage, driving conditions, and the manufacturer’s recommendations. Always consult your owner’s manual for the recommended viscosity and oil type. Consider the severity of any existing problems like leaks or sludge when making your choice. While full synthetics offer superior protection, high-mileage specific conventional oils are a more budget-friendly option. Additives can be useful for addressing specific issues, but they shouldn’t replace regular oil changes.
Frequently Asked Questions (FAQs):
Q: How often should I change my oil in a high-mileage car?
A: While some high-mileage oils claim longer intervals, it’s best to follow your owner’s manual or consult a mechanic. Generally, more frequent changes (every 5,000-7,500 miles) are recommended for older engines.
Q: What does “high mileage” mean for oil?
A: Generally, oils marketed for “high mileage” are formulated to address the increased wear and tear common in engines with over 75,000 miles.
Q: What are the benefits of using high-mileage oil?
A: These oils often contain additives to clean existing sludge, condition seals to prevent leaks, and reduce wear and tear on engine components.
Q: Can I mix different types of oil?
A: It’s generally not recommended to mix different types of oil (e.g., conventional with synthetic). If you must top off, use the same type of oil as what’s already in the engine.
Q: What’s the difference between conventional and synthetic oil?
A: Synthetic oil is engineered to perform better in extreme temperatures and offer superior protection against wear. Conventional oil is more affordable but requires more frequent changes.
Q: What is the importance of viscosity (like 5W-30 or 0W-20)?
A: Viscosity refers to the oil’s thickness. The numbers indicate its performance at different temperatures – crucial for engine protection in both hot and cold conditions. Always choose the viscosity recommended in your owner’s manual.
By considering these factors and reviewing the oils discussed, you’ll be well-equipped to make the best choice for your high-mileage vehicle, ensuring its continued reliable performance.
