B LUBRICANT, METHOD FOR SAVING ENERGY USING A GEAR LUBRICANT, PROCESS TO PRODUCE AN AUTOMOTIVE GEAR LUBRICANT, WHICH SAVES ENERGY, AND, LUBRICATING BASE OIL D A multigrade based automotive oil lubricant that comprises a traction coefficient less than 0.021. An energy-saving method, which uses a gear lubricant, which comprises mixing a multigrade gear lubricant by adding a base oil having a tensile coefficient of less than 0.021, and using a gear lubricant in one axle or differential. A process for producing an energy-saving automotive gear lubricant with a kinematic viscosity at 100 198 C greater than 10 cSt. A gear lubricant, which comprises a base oil derived from FT having a tensile coefficient of less than 0.015. A finished lubricant, which comprises a base oil derived from FT, with a traction coefficient of less than 0.015. A base oil having a tensile coefficient of less than 0.011 and a boiling point of 50%, by weight, greater than 582 198 C.
