Base oil definition
Base oil is found in all lubricants. A typical lubricant consists of 90% essential oil and 10% additives, but this is not always the case. The saturated, sulfur, and viscosity index characterize base oils by the American Petroleum Institute (API).
Level of Saturation
It is typical to find a saturated molecule in the base oil. Saturates are found naturally in this oil, although the refining process results in higher concentrations. The molecular bond of the oil is way stronger if the saturated content is larger. As a result, the loss of viscosity and resistance to breakdown and oxidation will be increased.
Level of Sulfur
Crude oil contains sulfur as a naturally occurring inorganic element. Because it reacts with oxygen, it can have a negative impact on the performance of an engine’s oil. Exhaust following treatment devices might also be harmful. Sulfur has both beneficial and negative features, notwithstanding the unfavorable aspects. In terms of oxidative stability, sulfur is an effective antioxidant. The lower the sulfur level, the less likely corrosion, and oxidation will occur.
Velocity Percentage
The Viscosity Index measures how viscosity changes as a function of temperature. Temperatures of 40°C and also 100°C are used to determine viscosity. The viscosity index measures a substance’s ability to withstand temperature fluctuations. In general, the viscosity of all oils increases when the temperature lowers and reduces when it increases.
