There are several different groups of base oils when it comes to using base oil, and you should understand their viscosity index and chemical composition before buying them from a base oil supplier. These variables will determine what type of lubricant you choose for your vehicle. Keep reading to learn more. We will look at the viscosity index of base oils and their lubricant properties. Once you have an idea of what type of oil you need, you can begin shopping for the best product for your vehicle.

Groups of base oils:

Before buying motor oil, it is essential to understand the difference between Groups I and II of base oils. Group I base oils are the most common type of industrial oil. Group II base oils are becoming more common as they are made from hydrogenated crude oil. This process removes unwanted components from the crude oil, leaving the refined oil colorless and clear. This type of oil contains little to no sulfur and is highly resistant to flow.

Their viscosity index:

Before you buy base oil for your engine, it’s worth checking the particular oil’s viscosity index (VI). This value is a dimensionless measure of how the oil changes viscosity with temperature. High VI values have less variation with extreme temperature changes. Viscosity index improvers are commonly used to increase the viscosity index of mineral base oils. Higher VI oils perform better in a wider temperature range, reducing wear and tear on the engine.

Their chemical composition:

There are many important considerations when determining the chemical composition of base oils. This type of oil contains high amounts of saturates (e.g., paraffin) and low amounts of aromatic hydrocarbons (e.g., cyclo-paraffins). Its pour point is less than -30 degrees Celsius, its kinematic viscosity at 100 degrees C is 3.5 to six cSt, and its Noack volatility is 6 to 14 wt %.

Their lubricant properties:

Before purchasing a lubricant, you should understand the differences between mineral and synthetic oils. While these oils differ slightly in price, synthetics can have a greater impact on the performance of your equipment. Knowing which base oil to use depends on your individual needs, including how you use your equipment.
