Is High Mileage Oil Worth It? Unveiling the Truth

As your car ages and accumulates miles, you might wonder whether switching to high mileage oil is a smart move. After all, it seems like overkill to use an oil specifically formulated for older engines. However, the benefits of high mileage oil can be well worth the investment in the long run. In this article, we’ll explore what high mileage oil is, its advantages, and whether it’s worth the extra cost.

What Is High Mileage Oil?

High mileage oil is designed specifically for older cars with 75,000 miles or more on the odometer. Unlike regular motor oil, high mileage oil contains special additives that improve engine longevity. Let’s delve into the benefits of using high mileage oil:

The Benefits

1. Extended Engine Life: Motor oil is crucial for lubricating and cooling hundreds of close tolerance moving parts in your engine. High mileage oil has higher viscosities and film strengths than conventional oils, reducing the risk of metal-to-metal contact. This protection helps extend the life of your engine.
2. Deposit Buildup Prevention: High mileage oils contain additives designed to eliminate deposit buildup. These deposits can lead to sludge formation, affecting engine performance. By using high mileage oil, you can keep your engine cleaner and minimize the chances of harmful deposits.
3. Seal and Gasket Maintenance: Aging seals and gaskets can become brittle over time, leading to leaks. High mileage oil includes conditioners that help prevent this issue. If you’ve noticed oil stains on the pavement where your car is parked, it’s a sign that your seals and gaskets may need attention. High mileage oil can help maintain their integrity.
4. Protection Against Rust and Corrosion: Moisture and acids can find their way into the engine, causing corrosion. High mileage oil provides an extra layer of protection, safeguarding your engine components.

Is It Worth the Extra Cost?

The answer depends on your specific situation:

• If Your Engine Is Leaking or Burning Oil: If your car’s engine is already leaking oil or burning it excessively, high mileage oil is definitely worth considering. The seal conditioners in high mileage oil can help address these issues.
• If Your Engine Is in Good Condition: If your engine isn’t leaking or burning oil and uses less than a quart over 6,000 miles, switching to high mileage oil may not be necessary. Regular oil changes with quality conventional or synthetic oil should suffice.

In summary, high mileage oil offers several advantages for older engines. It can extend engine life, prevent deposit buildup, and maintain seals and gaskets. However, if your engine is in excellent condition, the extra cost may not be justified. Evaluate your car’s needs and consult your mechanic to make an informed decision.

Remember, taking care of your engine now can save you from costly repairs down the road. Whether you choose high mileage oil or stick with regular oil, regular maintenance remains essential for keeping your car running smoothly. I hope you find this article helpful!
