3 Key Differences to Know Between Types of Oil

Understanding the different types of motor oil will give you a better understanding of how to make use out of it. Basically, you can categorize motor oil into four different types of categories for the best results. The four different types of motor oil that you have include:

  • Synthetic Motor Oil
  • Synthetic Blend Motor Oil
  • High Mileage Motor Oil
  • Conventional Motor Oil

1- Motor Oil Grade Designations

The rating system for motor oils comes from SAE, which classifies the oil based on the viscosity of the motor oil. The word viscosity basically means the oil’s ability to flow. You have oils that have a lower viscosity, but you also have oils with a higher viscosity. In addition, oil will change over time as it starts to cool. Whenever adding oil into your vehicle, you should always check the owner’s manual. 

With the different designations, you have synthetic motor oil. This oil runs through a chemically engineered process, and you will notice how the molecules have a more uniform shape to them. Generally, this oil gets formulated with a higher performing additive. Next, you have the synthetic blend motor oil. This combination uses more of a blend of conventional base oils for resistance to the oxidation. This oil can provide you with excellent abilities when it comes to low temperatures. Next, you have high mileage motor oil, which they have formulated especially for the newer vehicles to run over 75,000 miles. This type of motor oil has the advantage of lowering the oil burn off. Lastly, you have Conventional motor oil. This type of oil has been formulated so that you have a wider range of viscosity. Conventional motor oil is normally recommended for simple engine design. 

2- Look at the Additives

Another one of the areas where you will find key differences in the types of oils will come down to the oil additives that you have chosen. Sometimes, they don’t even list some of the additives like:

  • Detergent
  • Foam Inhibitors
  • Friction Modifiers
  • Antiwear Additives
  • Viscosity Index Improvers

While additives can make for an excellent addition to your vehicle, you have to keep the system fully balanced at all times as you’re doing this because it can also become a negative under the wrong circumstances. For example, while sulfur compounds do have anti-wear properties, if they come in excess quantities, they can start to reduce how much fuel economy you get, and they can have a negative impact on the catalytic converter of your vehicle. You also don’t want to add too much detergent because this affects the antiwear balance of your oil. 

In general, additives should represent anywhere from five percent to 30 percent of the given quantity of oil. How they will function within the oil base will depend on the viscosity and the type of oil as well. Each type of oil will have its own recipe, and it will be dependent on how well it works in the engine. 

3- How the Oils Differ

When the oil gets spilled, you have different types of oil that will have an impact differently. For example, the extremely light oils are considered highly volatile, and they have a high concentration of toxic compounds. Light oils, on the other hand, are considered moderately volatile, and this type of oil has a moderate concentration of toxic compounds. Next, on the list, you have the medium oils, and these are considered your average crude oils. Finally, you have the heavy oils, and these are the types of oil that if you spill them, they will have little to no dissolution. This type of oil will have a long-term impact. 

These are some of the main differences that you will find between the different types of oils. Each one will differ, so it can be helpful for you to do a little bit of your own research beforehand. In addition, this can help you to decide which type of oil you should use for your vehicle. Some will be a better choice than what the others are.
