No, it is not recommended to mix high mileage oil with regular oil.

Can You Mix High Mileage Oil With Regular Oil

Maintaining the correct oil in your engine is essential to its longevity and performance. Can you mix high mileage oil with regular oil, or do you need to stick to using just one type? The answer depends on which kind of engine you have and how you drive it. High mileage oil is formulated for engines with higher mileage, as the name suggests. It contains special additives that help protect seals and reduce wear and tear. Regular motor oil does not have these additives, so combining the two oils can work as a way to get the benefits of both types of oil. However, its not always recommended as it does pose some risks depending on your engine type and usage. Therefore, its best to check with your car manufacturer or an auto care professional before you mix high mileage oil with regular oil in your cars engine.

Can You Mix High Mileage Oil With Regular Oil?

It is often asked if it is safe to mix high mileage oil with regular oil. Generally speaking, it is not recommended to mix high mileage and regular oil. This is because the two oils have different properties that can affect the performance of your vehicles engine.

High Mileage Oils – What Are They?

High mileage oils are specially formulated for engines with more than 75,000 miles. These oils contain higher levels of anti-wear and detergent additives than regular motor oils as well as additional seal conditioners which help to keep the engine seals from leaking.

Types of High Mileage Oils

There are two main types of high mileage motor oils available: synthetic and mineral-based. Synthetic oils are more resistant to breakdown at higher temperatures and provide better protection against engine wear and tear. Mineral-based oils are also available but tend to break down more quickly under high temperatures, so they need to be changed more frequently.

Regular Motor Oils – What Are They?

Regular motor oils are formulated for engines with fewer than 75,000 miles on them. These motor oils contain fewer additives than high mileage ones, so they do not offer the same level of protection against wear and tear as a high mileage oil does.

Types of Regular Motor Oils

Regular motor oils come in a variety of weights or viscosities, which indicate how thick or thin the oil is when cold and how it flows when hot. Some common weights/viscosities include 5W-30, 10W-30, 10W-40, 15W-40, 20W-50 and 25W-50. The lower the number before the W (winter), the thinner the oil is when cold; conversely, the higher the number after the W (warm), the thicker it gets when hot.

Mixing High Mileage Oil with Regular Motor Oil – Is it Recommended?

Mixing high mileage oil with regular motor oil is not recommended by most automotive experts due to a variety of factors including different additives in each type of oil that can affect performance as well as different viscosities which can lead to sludge buildup in your engine over time if not changed regularly according to manufacturer recommendations. Customers have reported mixed results from mixing these two types of oil; some have reported smoother engine performance while others have experienced increased wear on engine components due to improper lubrication caused by incompatible levels of additives in their mixture.

Factors to Consider Before Mixing High Mileage Oil with Regular Motor Oil

Before mixing high mileage and regular motor oils together, it is important to consider several factors such as:

  • Oil Weight/Viscosity: The weight/viscosity of both types must be similar if mixing them together; otherwise one may be too thin or too thick for optimum lubrication.
  • Synthetic or Mineral-Based Oil: Synthetic based mixtures are easier on seals while mineral based ones can cause leaks.

Can You Mix High Mileage Oil With Regular Oil?

Yes, you can mix high mileage oil with regular oil. This is a viable option for many people who want to save a few bucks on their car maintenance costs. But there are some things to consider before doing so, and it’s important to understand the potential risks and advantages of mixing high mileage oil with regular oil.

Advantages of Mixing High Mileage Oil and Regular Motor Oil

The main advantage of mixing high mileage oil and regular motor oil is that it can help reduce the cost of car maintenance. High mileage oils are designed for older cars, which tend to be more expensive when it comes to servicing and repairs. By blending in some regular motor oil, you can reduce these costs while still providing your car with the lubrication it needs to run smoothly.

Another advantage of blending these types of oils is that it can improve the performance and quality of your vehicle. High mileage oils are specially formulated to provide extra protection against wear and tear, which can help improve engine efficiency and extend the life of your vehicle. Blending in some regular motor oil can further enhance this protection while also helping to reduce engine noise and vibration.

Disadvantages of Mixing High Mileage Oil with Regular Motor Oil

Although mixing high mileage oil with regular motor oil has its advantages, there are also some potential drawbacks that should be taken into consideration. One of the most notable disadvantages is that blending these two types of oils can lead to a loss in efficiency due to the different viscosities between them. This could result in reduced fuel economy or even engine damage if not done properly.

Another disadvantage is that mixing these two types of oils could increase the chances of damage occurring due to incompatible components in each type of oil. For example, if one type contains an additive that reduces friction but the other does not, then this could lead to increased wear on certain parts over time due to increased friction between them as they move around inside the engine.

What To Look For When Choosing The Right Combination Of High Mileage And Regular Motor Oils

When choosing a blend of high mileage and regular motor oils, it’s important to ensure that they are compatible with each other as well as being useful for your particular engine type. Compatibility is key here; using two incompatible types together could potentially cause problems down the line such as reduced efficiency or even engine damage if not done correctly. It’s also important to make sure that both types serve their purpose – for example, if one type contains detergents designed for cleaning out engines but another does not, then this could result in build-up over time which could cause problems down the road as well.

Alternatives To Blending Different Types Of Motor Oils

If you’re worried about compatibility issues or simply don’t like the idea of mixing two different types together then there are other alternatives available which may be more suitable for you such as using an additive or switching over completely to a synthetic blend instead. Additives are designed specifically for enhancing existing motor oils so they may provide more benefits than blending two different types together would do while switching over completely will ensure maximum compatibility as well as offering better performance overall compared to traditional blends or mixtures containing both synthetic and conventional options .

FAQ & Answers

Q: Can I mix high mileage oil with regular oil?
A: Yes, you can mix high mileage oil with regular motor oil. However, it is important to consider factors such as the oil weight/viscosity, type of oil (synthetic or mineral-based), and compatibility before doing so.

Q: What are the benefits of mixing high mileage and regular motor oils?
A: Mixing high mileage and regular motor oils can help reduce the cost of maintenance, improve vehicle quality and performance, and increase engine efficiency.
