What Is an Oil Life Monitor?
An oil life monitor is a smart system found in some cars that calculates how long the oil in your engine will last. It considers factors like:
- How far you’ve driven
- How you drive (slow, fast, or stop-and-go)
- The temperature outside
- The engine's working conditions
Cars with oil life monitors usually display a message or percentage on the dashboard when it’s time to change the oil. Unfortunately, Subaru didn’t include this feature in the 2015 Forester.

How Does the 2015 Subaru Forester Keep Track of Oil Changes?
While the 2015 Subaru Forester does not have an oil life monitor, it still helps you keep track of oil maintenance in other ways. Subaru uses simple reminders and guidelines to make sure you change your oil regularly. Here’s how:
Subaru recommends that you change the oil in your 2015 Forester every 6,000 miles or 6 months, whichever comes first. If you drive in extreme conditions, like very hot or cold weather or dusty areas, you may need to change the oil more often.
Your Forester has warning lights on the dashboard that can alert you to oil-related issues. One of these is the oil pressure warning light. If this light comes on, it means there’s a problem with your oil pressure, which could be due to low oil or a leak. This is a sign to check your oil right away, though it doesn’t measure oil life like an oil monitor would.
The owner’s manual for the 2015 Subaru Forester provides detailed instructions on how to take care of your vehicle’s oil. It includes recommended oil types, change intervals, and tips for keeping your engine in good condition. While this may not be as easy as having an oil life monitor, it’s still a useful guide.
Why Doesn’t the 2015 Subaru Forester Have an Oil Life Monitor?
You might be wondering why Subaru chose not to include an oil life monitor in the 2015 Forester. Many other cars around the same time did have this feature. Subaru tends to focus on simplicity and reliability, and they’ve stuck to traditional methods for oil maintenance.

Instead of relying on a sensor that estimates how long your oil will last, Subaru believes it’s better to follow specific maintenance intervals. This approach helps drivers avoid over-reliance on technology and encourages them to be more hands-on with their vehicle care.

How to Know When Your 2015 Subaru Forester Needs an Oil Change
Even though the 2015 Subaru Forester doesn’t have an oil life monitor, there are other signs to watch out for that let you know it’s time for an oil change. Paying attention to these will help keep your engine healthy and running smoothly.
# | Indicator | Description |
---|---|---|
1 | Mileage and Time | If it’s been 6,000 miles or 6 months since your last oil change, it’s time to schedule one. You can track this by keeping an oil change log or using an app to remind you. |
2 | Oil Appearance | New oil is usually clear and light amber in color. As it gets used, it becomes darker and thicker. Check your oil by pulling out the dipstick and looking at the color. If it’s black or gritty, it’s time for a change. |
3 | Unusual Engine Noises | Oil lubricates your engine, keeping the parts moving smoothly. When the oil gets old, your engine might start making strange sounds like knocking or grinding. This could mean the oil isn’t doing its job properly. |
4 | Oil Smell or Exhaust Smoke | If you smell oil inside your car or see blue or black smoke coming from your exhaust, your engine might be burning oil. This is a sign that something is wrong, and you should get your oil checked as soon as possible. |
Benefits of Regular Oil Changes for Your 2015 Subaru Forester
Even though your 2015 Subaru Forester doesn’t have an oil life monitor, regular oil changes are still important. They keep your engine in good shape and can prevent bigger problems down the road. Here are some benefits of changing your oil on time:
# | Benefit | Description |
---|---|---|
1 | Better Engine Performance | Clean oil helps your engine run smoothly. It reduces friction between the moving parts, allowing them to work efficiently. Old oil can slow down your engine and cause wear and tear. |
2 | Improved Fuel Efficiency | When your engine is well-lubricated, it doesn’t have to work as hard. This means it uses less fuel, which saves you money on gas. |
3 | Longer Engine Life | Changing your oil regularly helps prevent damage to your engine. Fresh oil protects the engine parts from heat and friction, which can cause serious damage over time. |
4 | Prevents Costly Repairs | If you don’t change your oil, it can lead to bigger problems, like engine failure. Fixing or replacing an engine is expensive, but regular oil changes can help you avoid these costs. |
