Oil Life 15 refers to the percentage of the remaining oil life in a Honda vehicle.
The Honda maintenance minder system calculates the remaining engine oil life based on driving habits and mileage.
When you see Oil Life 15 on your Honda’s information display, the engine oil has approximately 15% of its usable oil life left before you need an oil change. Essentially, you’ll require servicing soon — so you should schedule an appointment.
Now, the oil life percentage doesn’t refer to your oil level but your oil quality. When the engine oil life reaches 0%, your vehicle has degraded oil that has lost its ability to lubricate and protect the engine effectively. Driving with degraded oil could lead to engine damage or failure.
This oil life monitor is fitted in most Honda Motor Company models, including the Honda Accord, and Honda CRV.
