An oil change checklist is provided to help determine when an oil change is needed. The checklist includes 6 signs such as the oil dipstick showing the oil level is below the minimum mark, hearing knocking or rumbling noises from the engine, seeing smoke coming from the exhaust, smelling oil inside the vehicle, oil appearing dark or dirty, and the oil light illuminating on the dashboard. The document encourages scheduling an oil change appointment with Toyota of Clermont if any of these signs are present to keep the engine running properly and avoid potential damage.
