What to Look For in High Mileage Oil
When selecting high mileage oil, it's crucial to understand the unique requirements of older engines. Here are some factors to consider:

3. Compatibility with Catalytic Converters
- Some older oils can negatively impact catalytic converters, leading to decreased vehicle performance. Ensure the oil you choose is compatible with your vehicle's emissions system.
4. Manufacturer Recommendations
- Always refer to your vehicle’s manual for oil specifications. While high mileage oils typically cater to older engines, the manufacturer’s guidelines should not be overlooked.
