What are the different types of motor oils?

When searching for the best oil for high mileage cars, you must give yourself an idea about the different types of oils you might experience in the market. There are four common types of engine oil that you might encounter:

  1. Conventional oil

This is the Standard Oil that you can put in any regular vehicle. It provides you with the basic benefits and helps lubricate the engine and prevent overheating. However, while this oil is the cheapest among the others mentioned in this list, it is not providing you with additional benefits that you might want, like those related to reducing oxidation and preventing corrosion. Furthermore, when going with conventional oil, you will have to change your oil more frequently because this type of oil is expected to break down faster than the others.

  1. Synthetic oil

Synthetic oil is the top and highest quality oil among all the ones mentioned in this list. It provides you with extra benefits related to cleaning the engine and reducing oxidation, along with taking care of any corrosion if the oil has specific types of additives.

You don't have to worry about oil changes frequently because you can wait up to 10,000 miles without needing an oil change when going with synthetic oil. But, of course, this mileage threshold depends heavily on your vehicle type and the type of synthetic oil you choose.

  1. Blend synthetic oil
    Since synthetic oil is more expensive and might be affordable for many buyers, automotive experts and manufacturers decided to create a new oil that provides you with great benefits close to the ones the synthetic oil provides you with at a lower price. That's why they combined a mixture of synthetic oil and conventional oil.
  2. High mileage oil

Finally, the high mileage oil is the type of oil targeting vehicles with 75,000 or more miles. This oil understands that the older your car gets, the weaker it gets and the more benefits and help it needs from the engine oil. That's why this high mileage oil has more additives to help take care of the internal components in your engine and prevent corrosion and wear while taking care of minor engine leaks.

Should I choose synthetic or high-mileage oil?

Many of our readers reach out to us, wondering whether they should go with synthetic or high-mileage oil. The short answer is it all depends and differs on a case-by-case basis.

As we indicated earlier, both synthetic and high mileage oils provide your vehicle with great benefits and help enhance engine performance. However, each oil has its formula and targets specific benefits.

For example, the high mileage oil helps cover all minor internal breakage and enhances the seals if they have any problems. So that's why if you know for sure that your engine doesn't have any leakage or there are no issues in the internal walls, you don't necessarily have to go with a high mileage oil, and you can choose synthetic oil.

However, we still recommend that you consult your mechanic and know what is best for your vehicle. Your mechanic will have a good understanding of the main problems in your vehicle because these problems might not be as obvious to you as a normal driver.
