In the market, there are many types of engine oil with specialized characteristics suited to each car’s condition. Choosing the right engine oil will help reduce engine wear and ensure the car’s proper operation. If your car has traveled 75,000 miles or more, it’s time for you to find specialized oil brands for high-mileage vehicles instead of using ordinary oil. So, what is the best oil for high-mileage engines and what are they? Let’s follow this topic to learn more:
What is High Mileage Oil?
What should be considered as high mileage oil? If you search online for high mileage oils, you get thousands of results, but the problem is that there is no definitive idea on this matter. This oil is made with special base oils and anti-wear additives to minimize oil leaks and is formulated to protect car engines with over 75,000 miles and vehicles with longer oil change intervals.
Gradually, O-rings, gaskets, and seals, among other components, begin to deteriorate as the engine ages. They become less capable of performing their many tasks, including keeping the oil sealed inside the engine. That’s why we need a special oil for these situations. High mileage oil can alleviate common problems in older engines, such as worn gaskets and seals, high oil consumption, or oil pressure. So, what benefits can this type of oil bring:
- The ingredients in high mileage oil contain seal conditioners whose main role is to soften and rejuvenate the engine seals, which can partly prevent oil leaks and seal deterioration.
- The additives in this oil can enhance protection to limit engine wear. Furthermore, it also minimizes engine damage and reduces friction between metal parts.
- Compared to regular engine oil, high mileage oils can improve detergency as they contain additives that will keep your engine clean by reducing deposit buildup in the engine compartment.
When to Use High Mileage Oil – Answer
Your concern: what is the best time to switch to high mileage oils? As we mentioned above, when your car reaches about 120,000 kilometers or more, it is recommended to consider using high mileage oils. However, the exact number sometimes depends on the engine’s condition and the specific model, so be sure to ask your mechanic or the manufacturer before changing the oil type.
Another symptom is when you notice your engine is consuming more oil than normal and you will constantly need to refill the oil tank. This sign indicates that your car needs to switch to another type of car oil suitable for the car’s engine or needs to be checked to see if your car’s engine has problems.
Moreover, strange noises from the car engine are also one of the symptoms prompting you to use high mileage oil. Over time, regular oil is no longer able to lubricate your engine parts, causing them to rub against each other during operation, consequently, you will hear a loud noise or even wear and damage. Therefore, when they hear strange noises from the engine, car owners should have their car checked immediately and consider using high mileage oil if necessary.
