How to Buy the Best High Mileage Oil

1. Motor Age   

The age of the motor engine, as well as the mileage on the counter, are essential factors that you need to consider.

Most people will consider a motor engine with a mileage of above 75,000 miles to be old. The opinion on what engine we consider old varies from one motorist to the other, and from expert to expert.

You may want to use a high mileage oil on a vehicle with 75,000 miles or a little higher than this. There is no exact science to it. Whatever you choose, there is no harm done to the vehicle’s motor engine, even if it does not technically count as a high mileage vehicle.

2. Types of Oil

There are several types of high mileage motor oils on the market. Here are a few of the most common high mileage motor oils you will encounter.

2.1 Mineral oil

Mineral oil is fully organic and it contains little additives. Engine oil brands will market them as organic or conventional oil.

This type of oil is generally a little more affordable when compared to other types because it is cheaper to make.

However, the major disadvantage of the mineral oil is that it has a low tolerance to very high temperatures.

2.2 Semi-synthetic oil

Just like its name suggests, the semi-synthetic oil is a hybrid between synthetic and mineral oils.

This type of oil is one of the most popular motor oils on the market because it has the right balance between efficiency and price.

Moreover, it comes in many SAE viscosity ratings, which makes it versatile and adaptable to a wide range of vehicles out there.

2.3 Synthetic oil

Synthetic oil is a wholly man-made oil. It has the highest number of additives and usually works in many vehicles, whether it is a new vehicle or a high mileage one.

The major disadvantage of synthetic oil is its price. Indeed, when compared to other types of oils, it is more expensive because it is costlier to make a synthetic oil than mineral oil.

3. Viscosity

Each vehicle manufacturer usually makes and calibrate their motors for use with a specific oil viscosity. The SAE rating is the most common way to denote the oil viscosity.

The most common SAE rating for a high mileage oil is generally 10W40. The “W” stands for winter. The lower the value of the “W,” the better it would be able to withstand cold temperatures.

For example, a high mileage engine oil rated at 5W30 will flow better and has a superior viscosity at low temperatures when compared to an engine oil with a rating of 10W40.

If you live in a cold environment, it is always best to go with a high mileage oil that has a lower SAE rating like 5W30.

However, you should always refer to your manufacturer specs to see which type of viscosity is mostly suited to be used in your high mileage vehicle.

4. Additives

Additives are simply chemicals that oil manufacturers add to enhance the performance and effectiveness of their oils. Almost all the best high mileage oils on the market have some additives in them.

For example, there can be an additive that minimize regular wear and tear. Additionally, other additives will make the oil more resistant to high temperatures, as well as high pressures.

Therefore, you must ensure that the engine oil you are interested in has additives inside that will make the engine run more efficiently.

Conclusion

As we have seen, every high mileage vehicle owner needs to have the best high mileage oil to keep their engine in peak performance.

A good oil will not only make the engine run more efficiently, but it will also minimize wear and tear from happening, which in turn will make the engine last even longer.

And you can be sure there is at least one oil that will work well for your high mileage vehicle in our list above.
