An oil is rated for viscosity by heating it to a specified temperature, and then allowing it to flow out of a specifically sized hole. Its viscosity rating is determined by the length of time it takes to flow out of the hole. If it flows quickly, it gets a low rating. If it flows slowly, it gets a high rating.
ulei gros = mai vascos
ulei subtire = mai putin vascos
ca fapt divers : sticla ( geamuri, recipiente, etc...) este considerata a fi un lichid extrem de vascos
