Abstract

Methods and Systems for monitoring an engine fluid level in a fluid recipient are described. In one example, the method comprises, during a fluid replenishing procedure, detecting when the fluid level reaches a level associated with the recipient being full; in response to the detecting, triggering a timer corresponding to a predetermined number of operating hours of the engine based on a fluid volume capacity of the fluid recipient; when the timer expires, verifying the fluid level; and issuing a first alert signal when the fluid level is at the level associated with the recipient being full and the timer has expired.
