Types of motor oil

  • Mineral oil

The first oil type is prevalent. It is mineral oil, and it is made from entirely organic substances. This oil is extracted directly from the ground. The extraction process is so thorough that the product retrieved comes with little to no additives. Thee mineral oil is often sold as a conventional oil r=or an organic oil, and as such, they’re less expensive than the other oil kinds; even though it is cheap to make, the mineral oil has a low tolerance to heat; thus, it gets affected easily.

  • Semi-synthetic oil

Another oil type in this article is the semi-synthetic oil. This product is a mix of both mineral and man-made oils to create a new product. The combination means that this oil has different properties and shared advantages from the two-parent oils. This makes it more powerful and efficient. The efficiency of this oil aids in its demand, as it is the most common oil type today. The semi-synthetic oils come in many viscosity ratings, and this adds variety to the kinds of vehicles it can be used for.

  • Synthetic oil

The synthetic oils are man-made oils featuring a lot of additives and chemicals. They are used for all kinds of vehicles, be it high mileage or brand new models. These oils are the most expensive units amongst all oil types. They are pricier because it takes more money to create synthetic crude than it is to make a conventional oil.

Synthetic vs. High Mileage Oil

Synthetic oils, as stated above, are created by man. They feature chemical and artificial additives and chemicals that are costly to come across. The High mileage oils are also synthetic oils made from chemicals and additives. The significant difference between these two oils is their intended use. While the high mileage oils are meant for older engines, synthetic oils can be used for new and old cars with ease. This makes the artificial a little more versatile in operation.
