How Long Will 15 Oil Life Last?

On average, though, 15 oil life is around 3500 miles. Of course, a variety of factors can affect how long your oil life lasts: what kind of oil you choose (stick with reputable brands like Mobil 1), how much you choose to fill the engine with, how tightly you screw on the oil cap and whether or not you check the level regularly.

It’s also important not to ignore that “change engine oil” light on your dashboard. This is an indicator that your car has sensed a drop in its own efficiency and needs a change ASAP. If ignored, this could lead to serious damage within your vehicle’s system—so when it comes on, listen!

And lastly make sure to use the correct type of oil for your engine. Using synthetic blends or full-synthetic oils can increase mileage by up to 5000 miles in some cases. You can consult your vehicle’s owner manual for more information about which type of oil is best for it.

15 oil life is about 3500 miles.

Generally, 15 oil life is about 3500 miles. It’s important to note, though, that this can vary based on your driving conditions. If you drive a lot in stop-and-go traffic or spend a lot of time driving at slower speeds around town, your oil will last less long than the average of 3500 miles. On the other hand, if you spend most of your time driving on highways and taking longer trips at higher speeds, your oil will last longer than average—and won’t need to be changed as frequently.

This depends on your driving habits and the type of oil used.

Generally, 15% is a good number to have in mind. Your owner’s manual will recommend an oil change interval that best suits the vehicle’s needs. If you follow it closely and live in a warm climate, this could be 12 months or 12,000 miles. If you’re a stop-and-go city driver who doesn’t get around much during wintertime, maybe this ends up being 4 months or 4,000 miles.

If you drive in stop-and-go traffic, it will last less time than if you drive on highways.

If you’re driving in stop-and-go traffic, your oil will last less time. Stop-and-go traffic creates more wear on your engine because the vehicle is constantly accelerating and stopping, which uses up oil. The reverse is true for highway driving—it’s consistent, so it doesn’t put as much strain on the engine.
