Why should you reset the oil change light after a service?

Resetting the oil change light after a service is crucial for maintaining an accurate record of your vehicle's maintenance schedule. The oil change light is a reminder system that alerts the driver when it’s time to change the oil, based on either mileage or engine running time. If this light is not reset after an oil change, the driver may be misled into thinking that an oil change is still needed when, in fact, the service has already been performed. This could lead to unnecessary oil changes, potentially wasting resources and impacting the vehicle's maintenance history. By resetting the light, you ensure that the next scheduled oil change is clearly indicated, helping to promote the longevity and efficiency of the engine.
