1. A method for controlling the warming of engine oil during engine warm-up from a cold start, the engine having a crankshaft, comprising:
- selectively driving an oil shear device via engagement and disengagement of a clutch coupled between the crankshaft and the oil shear device during the cold start based on engine oil temperature the engagement after the engine reaches a minimum engine speed after cranking; and
directing the powertrain lubricants to the oil shear device.

Abstract
Methods for achieving efficient vehicle component heating are provided. One example method for controlling the warming of powertrain lubricants during engine warm-up from a cold start, the engine having an output crankshaft, includes selectively driving a lubricant heating device with the crankshaft during the cold start based on lubricant temperature. The method further includes directing the powertrain lubricants to the lubricant heating device.
