Oil changes are important for maintaining a healthy car, but it can be tricky to determine how often your vehicle needs them. Knowing approximately how many miles a vehicle can go with 15 oil life remaining can help you stay on top of the oil change schedule.

Important Factors

The answer to this question depends on a few things,

    • Driving conditions – the type of driving you do (highway, city, off-road, etc.) can have a huge impact on how long your oil will last. Generally, stop-and-go city driving is harder on the engine and its oil compared to driving primarily on highways.
    • Vehicle make and model – each make and model of the car can have unique oil usage characteristics. Additionally, the year the car was manufactured and the age of the vehicle can both impact how long the oil will last.
    • Type of oil – the oil grade and brand you use can also affect how many miles the oil can go.

Oil Life at 15%

At 15%, most experts recommend that you change your oil soon. While a vehicle can usually still travel some distance with 15% oil life remaining, this number can vary greatly. Generally, however, a car can drive up to 1,000 more miles with 15% oil life left.


Oil changes are essential for vehicle maintenance and longevity, but how often they need to be changed and how many miles you can drive before the oil needs to be changed can vary greatly. As a general rule, when the oil life reaches 15%, you can drive up to 1,000 more miles before changing the oil. However, this number can vary depending on your make and model, type of oil, and driving conditions. Be sure to consult your vehicle’s manual to ensure you are following the proper oil change schedule for your car.
