Neutrosophic statistical analysis of the viscosity variation of semi-synthetic and synthetic sae 10w30 oil as a function of mileage travelled

Abstract

The comparative research between Kendall GT-1 Max Motor Oil SAE 10W30 (Synthetic) and Kendall GT-1 High Performance Motor Oil SAE 10W30 (Semi-synthetic) arises from the concern of vehicle users about the use and advantages of each type of oil, so it was decided to develop the evaluation of the variation of kinematic viscosity as a function of the mileage traveled, measured from the last oil change in public service vehicles. Kinematic viscosity is one of the most significant properties for the correct operation of a lubricant and a Stokes viscometer was used for its measurement. The objective of this research is to carry out a neutrosophic statistical analysis on the variation of viscosity of semi-synthetic and synthetic sae 10w30 oil as a function of mileage traveled. Theoretical, empirical and mathematical statistical methods were used for this purpose. As a result, the synthetic oil showed a 22.31% decrease in kinematic viscosity, while the semi-synthetic oil degraded by 38.89% after having traveled 7000 km. By applying hypothesis testing and neutrosophic statistical techniques, it was shown that there is indeed a significant difference between the viscosity degradation percentages between the two types of lubricating oil; therefore, the use of the synthetic oil is justified, since it has better characteristics to minimize viscosity degradation, which contributes to the extension of the useful life of the engine's moving parts, since it has better lubrication characteristics.
