2015 Subaru Legacy 2.5i Premium engine oil capacity

Before you can change your oil, you’ll first need to find out how much motor oil your 2015 Subaru Legacy 2.5i Premium requires
A 2015 Subaru Legacy 2.5i has an oil capacity of 5.1 quarts or 4.8 liters. Make sure that you purchase enough engine oil, as failing to do so may result in damage to your vehicle. 

What kind of oil does a 2015 Subaru Legacy 2.5i Premium need?

Depending on your vehicle, the type of engine oil you’re going to need to buy might differ. For instance, if your
has a 2.5-liter engine, Subaru recommends drivers purchase 0W-20 synthetic motor oil but 5W-30 motor oil for the 3.6-liter engine
Both types work well in any climate—especially colder climates, so you don’t have to worry if it starts freezing outside. It also prevents further damage to your engine, which could result from using the incorrect engine oil. 
You may also be wondering if you should use synthetic or conventional engine oil. Subaru recommends that its drivers use synthetic oil, so it’s best to stick with that to optimize your vehicle’s performance. 
For your 2015 Subaru Legacy 2.5i Premium, here are good options: 

How often to change oil on a 2015 Subaru Legacy 2.5i Premium

With a couple of great choices to pick from, you’ve got to learn how often you should be doing an oil change once you’ve bought some. 
Subaru recommends that their drivers look into an oil change every 3,000 to 5,000 miles if you’re using synthetic oil. 
In addition to that range, you should also be on the lookout for the following:  
  • Strange noises
    coming from the engine 
  • New smells, especially anything that smells like oil, smoke, or burning
  • Performance changes 

How to change your oil and oil filter

To do an oil change for your 2015 Subaru Legacy 2.5i Premium, you need a socket wrench, a drain pan, and a filter wrench that can remove the old oil filter. 
You should start by running your engine for at least five minutes—more if you’re experiencing colder weather. Doing so ensures your vehicle reaches its normal operating temperature. Once your engine has  been running for a while, turn it off,
pop the hood
, and follow these steps: 
  • Find and remove your oil fill cap
  • Get underneath the engine and remove the oil drain bolt and washer, draining the old oil into the drain pan 
  • Remove the old oil filter and let the oil drain 
  • Replace the old filter with the new filter
  • Remove the oil drain bolt and use a new washer and tighten it to 29 lb-ft
  • Refill the engine with your new oil and replace the fill cap 
Use the dipstick as an indicator of when you’ve added enough replacement engine oil. Run the engine again once you’ve finished everything, and double-check for any leaks. To make sure that you’ve done the oil change correctly, check that the
oil pressure light
has turned off. 
Finally, clean up any oil that has spilled—don’t toss it out—but collect it in a sealed container and bring it to your nearest recycling depot. 
After changing your oil, it’s a good idea to turn on your car and let your engine run for about 30 seconds before you check the oil level. This will give you a more accurate measurement, and you’ll be able to top it off if necessary.
