Abstract
A method for warning of insufficient engine oil for a vehicle includes: determining, by a controller, whether conditions for determining that the vehicle has insufficient engine oil are satisfied, after an engine of the vehicle is started; determining, by the controller, whether an integrated value obtained by integrating a difference between a target operating value and an actual operating value of a hydraulic continuously variable valve timing (CVVT) device included in the engine within an operating time period of the hydraulic CVVT device is equal to or greater than a reference difference value, when the conditions for determining whether the vehicle has insufficient engine oil are satisfied; and determining, by the controller, that the vehicle has insufficient engine oil based on counting information on the number of times the integrated value, obtained by integrating the difference between the target operating value and the actual operating value, is equal to or greater than the reference difference value.
