Best Oil For High Mileage Engine [Top 5 Picks Reviewed]
On the market, there are many different types of engine oil with specialized features suitable for each car’s condition. Choosing the right motor oil will help reduce engine wear and keep the car running smoothly. If your car has reached 75000 miles or more, it’s time for you to find specialized oil brands for high-mileage vehicles instead of using regular 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 is to be considered high-mileage oil? If you search the Internet for high-mileage oils, there are thousands of results, but the problem is that there are no definitive notions about this question. This oil is manufactured with special base oils and anti-wear additives to minimize oil leaks and is formulated to protect car engines with over 75000 miles and vehicles with longer drain intervals.
Gradually, O-rings, gaskets, and seals among other components start to deteriorate as the engine ages. They become less capable of carrying out their many tasks including one that involves keeping oil sealed inside the engine. That’s why we need a special oil for these situations. High mileage oil can militate the problems commonly in older engines like worn gaskets and seals, high oil consumption, or oil pressure. So, what benefits this type of oil can give:
- The ingredients in high mileage oil contain seal conditioners with the main role of softening and rejuvenating engine gaskets and seals which can partly prevent oil leaks and seal deterioration.
- The additives in this oil can improve protection to limit engine wear. Not only that, it also minimizes engine damage and reduces friction between metal parts.
- Compared to regular engine oil, high-mileage oils can improve detergency since they include additives that will keep your engine clean by reducing the deposit accumulation in the engine compartment.
When To Use High Mileage Oil – Answered
Your concern: when is the best time to switch to high-mileage oils? As we said above when your car reaches around 75000 miles (120000 kilometers) or more, it’s recommended to consider using high-mileage oils. However, sometimes the exact number will depend on the engine’s condition and specific model, so make sure to ask your mechanic or manufacturers before changing the type of oil.
Another symptom is when you notice that your engine consumes more engine than normal and you will have to constantly refill the oil tank. This sign shows that your car needs to change to another type of car oil suitable for the car engine or needs to be checked to see if your car engine has any problems.
Moreover, strange noises from the car engine are also one of the symptoms telling you to use high mileage oil. Over time, regular oil is no longer able to lubricate the parts in your engine, causing them to rub against each other when operating, as a result, you will hear a loud noise or even wear and damage. Therefore, when hearing strange noises coming from the engine, car owners need to have their car checked immediately and consider using the high mileage oil if necessary.
