The purpose of this experiment is to test the viscosity of motor oil under different measures. The viscosity of four brands and four temperatures of oil will be tested to determine whether the viscosities of many brands of motor oil differentiate. Finally, the viscosity of synthetic and mineral oils will be tested to find out whether there is a difference in viscosity between the two. For this experiment, first heat 300mL of any oil. Then, as the oil reaches the appropriate temperatures, put a sample of 75mL of the oil into the corresponding beaker. Once the oils have cooled down to 70°C, pour the oil into a 100mL burette. Next, time how long the meniscus of the oil takes to flow from the 60mL mark to the 80mL mark. Record the data. Repeat these steps for each oil brand & type combination. This experiment shows that the viscosity of motor oil increases after it is heated. It has also proven that the Castrol brand is the most viscous of the Synthetic oils, and the Valvoline brand is the most viscous of the Mineral oils, and that mineral oils are more viscous than synthetic oils.
