5 Best Oil For High Mileage Cars In 2020

Are you looking for the best oil for high mileage car? Well, in that case, you have come to the right place. We have gathered some very important pieces of information that you must know before you opt for any high mileage oil for your car. In this article, we are going to answer the most frequently asked questions about the best oils for high mileage engines. Moreover, we have recommended the best high mileage oil brands, from which you can choose any.

What is a High Mileage Car?

Before we tell you about the best oil for high mileage cars, let’s discuss which cars are considered high mileage cars and whether you need high mileage oil or not.

There is no absolute answer to this question. However, any car that is driven more than 100,000 miles can easily come under the umbrella of high mileage cars. Usually, the standard limit for cars is either 300,000 or 400,000 miles.

If you drive between 12,000 to 15,000 miles annually, it means you are standing at an average limit. But if you drive more than this, then you must consider switching to high mileage oil.

When you should switch to High Mileage Oil?

There are many considerations when it comes to switching to high mileage oil. One of them is whether you have reached your standard limit. If you have driven over your standard mileage, you must consider getting high mileage oil for your car.

Moreover, it depends on where you are driving. Driving on a highway puts less strain on the engine, because you drive continuously. It gives enough time to your engine to reach a stable temperature due to which it can operate at its full efficiency.

However, when you drive in the city, you have more starts and stops, which doesn’t allow your engine to achieve a steady temperature to operate efficiently. This is why your engine may wear out more easily.

In this case, you may need to switch to high mileage oil at 80,000 miles. If you drive mostly on highways, then you have the leverage to go up to 100,000 miles to 150,000 miles before you get high mileage oil for your car.

Here are the top 5 options of the best oil for high mileage cars for you to choose from if you are about to switch to high mileage oil.
