METHOD AND SYSTEM FOR ESTIMATING ENGINE OIL LIFE BASED ON VISCOSITY |
摘要 |
A method and control module for indicating engine oil life includes a viscosity determination module determining a viscosity of the engine oil based on an engine oil pressure and engine oil temperature. The control system further includes a comparison module comparing the viscosity of the engine oil to a threshold and generating a warning signal in response to comparing the viscosity.
