For high mileage cars, it is important to look for oils with API SN or SN Plus certification as they are specifically designed to meet the needs of older engines.

High mileage formulas are specially formulated to cater to the needs of older engines with higher mileage. These formulas contain additives that help reduce wear and tear, prevent leaks, and improve overall engine performance. Look for oils that are labeled as “high mileage” or “HM” on the packaging.

3. Consider Your Driving Habits

If you use your car for long commutes or frequently drive in extreme weather conditions, it is important to choose an oil that can withstand these conditions. Look for oils that are labeled as “all-season” or “extreme performance” as they are designed to provide better protection in harsh conditions.

4. Choose Synthetic Blend or Full Synthetic

For high mileage cars, it is recommended to use synthetic blend or full synthetic oils as they offer better protection and performance compared to conventional oils. Synthetic oils are also known for their ability to reduce oil consumption and improve fuel economy.

5. Consider Your Budget

While it may be tempting to go for the most expensive oil, it is important to consider your budget. High mileage oils can be slightly more expensive than conventional oils, so make sure you choose one that fits your budget without compromising on quality.

6. Read Reviews

Before making a purchase, make sure you read reviews from other customers who have used the product. This will give you an idea about the real-life performance of the oil and help you make an informed decision.
