In high mileage oil, with the regular oil composition, some additives are mixed. These additives remove the frictional effect of the oil. That’s how the efficiency of the oil is increased. Also, these additives help to reduce leakage in the seal or gasket.

#2 – Detergent:  

Detergent helps to clean the sludge of the engine. This is really helpful as it ensures the optimum performance of the engine. Thus this oil becomes more effective.

In vehicles with more than 75000 miles of running history, engines parts can get damaged. Due to this long time of service, the strength of the materials also decreases.

Antioxidants prevent damage to these parts. It eliminates the possibility of corrosion. Most importantly, these additives help to reduce the wear and tear of internal parts.

How does high mileage oil increase engine performance?

If you use high mileage oil in your vehicles, you can see the visible changes in the performance of the engine. Here, I’m sharing some of the things that will be improved after using high mileage oil:

Lower oil consumption:  

High mileage oil is thicker than regular oil. So, less oil is needed to complete the lubrication or cooling function. High mileage vehicles may have leakage in the seal or gasket. In that case, it will provide protection. So, no oil will step out. And you will save more money as well.

Reduce noise:

In high mileage vehicles, due to wear and tear of engine parts, unexpected sounds may generate. This can be irritated for the user. The good news is, that using high mileage oil can solve this issue. And thus, driving can be more hassle-free and enjoyable. 

Reduce engine smoke:  

As you know, in high mileage oil, there are some additives mixed. These additives help to reduce the emission of blue or black smoke. 

Engine cleaning:  

Due to long time use, sludge can be produced inside the engine. This sludge resists the continuous motion of rotating parts inside the engine. Using this oil will keep the engine clean and thus solve the issue.

High mileage oil Vs regular oil: What’s the Differences

Well, now you know what is high mileage oil and how it can be useful in older vehicles. But have you noticed, how it differs from regular oil?

If you have read everything till now, you may have already discovered the differences. If not, don’t worry. Here, I’m summarizing the differences between high mileage oil and regular oil:

  • Regular oil only provides lubrication to engine parts. On the other hand, high mileage oil not only provides lubrication but also reduces engine damage.
  • There are no additives mixed in regular oil to provide wear protection. So, during use, it will lose its viscous properties. But high mileage oil will continue to serve for a long time due to the presence of the additives.
  • For newer vehicles or vehicles that are more fuel economic, regular oil can be good. But high mileage oil can be used in both newer and older vehicles. It will perform well in every case.

When to use high mileage oil?

So, here comes the next topic, how do you know that you need to use high mileage oil?

There are some symptoms that indicate that your vehicles need this oil. After a long time of service, as the machine parts get damaged, it decreases the performance,

Here, I’m sharing some situations, under which you should switch to high mileage oil if you are using a regular one.

  • If you observe excess sound when starting the engine, it may indicate that the engine parts are getting damaged. So, in that case, your vehicle needs high mileage oil. This will reduce the sound and provide protection as well.
  • If you see oil under the parking area of your car, that means oil is leaking out. In high mileage vehicles, that is a common thing. Since the seal and gasket get damaged, it begins to leak. Then, you should check whether using high mileage oil solves this or not.

In the above scenarios, using high mileage oil can be a better decision than sticking to regular oil.
