4 cSt (VHVI-4 base oil)
Base oil of group III (VHVI-4) is a high-quality synthetic oil obtained through the hydrocracking process from crude oil. This process involves converting crude oil into more stable and cleaner components under high pressure and temperature, making VHVI-4 an ideal component for formulating motor oils with improved performance properties, high oxidation stability, durability, and enhanced fuel economy.
