High Mileage Oil Buyer’s Guide

It doesn’t matter if you are using an old car or something that bit newer if you are covering more miles than most, it is important to ensure you have the right oil. A high mileage oil helps to protect the car on its daily commute when it has racked up the miles and is built to stand up to the demands of a constantly increasing odometer. 

Because of this, we have created the following buyer’s guide. It details everything worth knowing when it comes to shopping for these products.

Why Use A High Mileage Engine Oil

Sludge Removal

This is particularly important with older cars that experience this problem more often and is one of the main purposes for many when buying these oils. When it gels or solidifies, a sludge-like oil can form which impacts its performance and blocks lubrication needed to keep things running smoothly. A quality high mileage oil will work to break this down so the vehicle can run as expected.

Designed For Older Vehicles

Any car of a certain age will start to need more care and attention than it used to. this is where quality gas and oil is important. Not only is it designed to help the engine work seamlessly, but it makes it more likely that the car will make it through another year without needing expensive repairs.


Because of their unique formulas, high mileage engine oil tends to last longer than conventional oil in an old vehicle. Although it is always important to check the levels, and more frequently the older the car, most of these products will give you longer between needing to apply more.  


Despite being a tailor-made product designed to keep older cars (or cars with plenty of miles on the clock) in good working order, they are often similarly priced to conventional oils. This means that the user will not have to part with so many dollars to get their hands on a product that has a specific purpose. The same can’t always be said about other types of car-related products.


You never know what is going on under the hood, but knowing that you have poured quality oil that will protect the car can give you confidence when taking the car on the highway. When things start to go wrong it can make it difficult to depend on an older car, but this is the sort of product that helps to inspire trust in the car.

Cleaning Additives

Most products in this niche will come with a formula that includes cleaner agents. This can help make the engine run smoother, and protect it from wear and tear.

Protects Seals

The additives in a high mileage engine oil can protect the seals that may otherwise be impacted by wear and tear. This can prevent leaks which results in costly repairs. Because an aged car will usually burn through oil faster, this can impact these parts. These oils last longer, providing more protection.

Different Types Of Engine Oil

You may have seen the options at the gas station, and gone for the most affordable in the past. But with any vehicle with lots of miles on the clock, it becomes important to know what the difference is between them:

Synthetic Oil

These are a common option, made up of additional chemicals and other additives to enhance the formula. They are not specific to any type of car making them a good universal option but they are the most expensive type of engine oil available. They are made to reduce loss from evaporation, are good at handling extreme temperatures and are resistant to sludge related issues.

Mineral Oil

Made of organic substances, it is one of the purer types of oil, derived from the ground with minimal additives. This might sound impressive, but without some of the additives that other formulas have, it is cheaper and can be affected by the heat, causing it to lose some of its benefits. 

Semi-Synthetic Oil

Sitting somewhere between the previous two types, this contains additives, but not as many as purely synthetic oil. There are benefits to both types and this makes for a more affordable option that is still able to provide multiple benefits. They are made to be used in a variety of cars, just check the viscosity rating to ensure it is a good match.

When Do You Need A High Mileage Engine Oil?

Although it can be used sooner, it is recommended that these oils are used once the car reaches 75,000 miles. This is a common time for many people to trade in their car and opt for something with fewer miles on the clock. However, anyone picking up a car with this many miles or aware that theirs is close to or over this mark should start to use a high mileage engine oil to protect it and help prevent unwanted buildup. 

Is High Mileage Engine Oil Any Good?

Yes, it is. The benefits mainly apply to older vehicles or those with over 75,000 miles on the clock. Because they can protect the engine and ensure that everything under the hood works as it should. Because the oil tends to be heavier, and contain more detergents, they can remove sludge and keep the moving parts in good working order.

How Much Does High Mileage Engine Oil Cost?

Although they are priced a little higher than conventional engine oil, the benefits can save the user money. Costly repairs are worse than pricier oil, and even though they are often more expensive, it isn’t by a lot. Not to mention the fact that they last longer, so to prevent you from constantly having to top up the oil, a high milage product is ideal.
