Oil life is a measure of how much longer your current engine oil can provide protection for your vehicle’s engine. When the oil level reaches 15%, it means your engine oil is nearing its end and you need to replace it as soon as possible. But how much longer can you actually drive on 15% oil life without damaging your engine?

Calculate Oil Life Left

To find out the exact amount of miles or kilometers you have left to drive with only 15% oil life, you need to check your vehicle’s manual for its oil change interval. This will let you calculate the amount of miles or kilometers your engine oil can last before it needs to be replaced. Once you know this, you can determine how long you can drive on 15% oil life.

Maximize Oil Life

If you need to extend oil life as much as possible, here are some tips that can help:

    • Check your oil regularly: Check the oil level at least once a month and top it up when necessary.
    • Change your oil filters: Don’t forget to replace your oil filters whenever you change your engine oil.
    • Change your oil on time: Don’t wait until your oil life indicator reads 15%, change your oil every 5,000-7,500 miles or once a year, whichever comes first.
    • Drive sensibly: Avoid rapid acceleration and hard braking as these will put extra strain on your engine oil.


If you follow the tips above, you will be able to extend the life of your engine oil beyond the 15% reading and get extra mileage out of it. However, it’s important to remember that once the oil level reaches 15%, you should replace it right away to avoid any damage to your engine.
