The viscosity of a Yacco lubricant represents its resistance to flow. High viscosity forms a thick layer that separates moving parts and thus increases the protection of mechanical parts. Lower viscosity reduces friction and thus helps save the energy used for a given movement.
Viscosity is often referred to as grades or classes defined by standards. Thus, ISO VG grades are widely used in the industry and SAE grades in the automotive sector. Yacco lubricants are no exception to the rule: the degree of viscosity of the lube presented is indicated on every Yacco lubricants' product information sheet.
