Frequently Asked Questions (FAQs)

High mileage oil is designed for vehicles with more than 75,000 miles. Such oil features additives that help protect seals. This leads to less leakage and oil burn-off, which can be common in older cars. If your vehicle is high-mileage and high performance, it's suggested that you go with this type of synthetic oil.

2. Does high mileage motor oil make a difference?

Reduced oil consumption: High mileage vehicles tend to leak and burn off more oil than younger cars due to degraded engine seals. High mileage oil rejuvenates degraded seals, which leads to less oil consumption and burnoff. Less engine sludge: Older engines tend to accumulate sludge left behind by other motor oils.

3. Is synthetic oil better than high mileage?

So which one is better? The short answer is full synthetic is always better, but cost is the main reason why I buy high mileage oil vs synthetic oil. If you have over 75,000 miles on your modern car or truck, consider switching to a high-mileage motor oil.

4. Is using high mileage oil necessary?

Importantly, high mileage oil helps prevent aging seals and gaskets from becoming brittle and causing leaks, which are usually evidenced by oil stains on the pavement where the car is parked. This can lead to increased oil consumption and even costly engine damage.
