When a yellow or red oil can-shaped warning light appears on the dashboard, it is the vehicle's clear indication that engine oil needs to be changed or replenished. It is advisable to stop and check the oil level promptly, topping up with oil of the same specification if needed. A flashing red light indicates severe oil deficiency or abnormal pressure, requiring immediate engine shutdown to prevent wear on critical components like pistons and crankshafts due to lubrication failure. Additionally, metal grinding noises during cold starts, increased idle vibration, sluggish acceleration, or abnormal fuel consumption exceeding 10% may signal degraded oil quality and reduced lubrication performance. If the dipstick reveals black, viscous oil with metal particles or emulsification, its cleaning and lubricating properties are compromised, necessitating immediate replacement. Maintenance alerts vary by model-some trigger at fixed intervals (e.g., 5,000 km), while others assess oil life based on driving conditions. Monthly oil checks are recommended, especially for vehicles frequently used for short trips, as oil degrades faster in such cases. Addressing these warnings promptly prevents minor issues from escalating. Routine oil changes cost around a few hundred ringgit, whereas delays could lead to engine overhauls costing thousands.
