You're looking for ways to decrease friction in the engine block between the rods, pistons, cylinder walls, transmission gears, rear end gears, etc. Aside from using different viscosity oils, you would have to be willing to rebuild the whole engine and drivetrain. Your drivetrain losses are pretty much set from the factory.

Essentially everytime you convert the mechanical energy from one system (i.e. the engine) to another (the input shaft on the transmission) you loose energy in the forms of heat, friction and other things. To reduce this or even change this, you would need to basically redesign the drive train.
