2015 Ford Fusion engine oil capacity

The 2015 Ford Fusion comes with several different engine options, and each one has its own oil capacity. 
Not sure what type of engine your 2015 Ford Fusion has? There are a few different places you can check to find out:
  • Your owner’s manual
  • Your vehicle purchase or registration papers
  • The label on your driver’s side door jamb
  • Information on the engine itself
The three main engine options for the 2015 Ford Fusion are the 1.5-liter EcoBoost, 2.0L EcoBoost, and 2.5L engines. 
However, the measurements in liters here aren’t your oil capacity—they’re your engine displacement, which is the total volume of your engine’s cylinders. To figure out your oil capacity, you’ll need to check your owner’s manual for the capacity that corresponds with your engine type. 
Here are how the oil capacities on various 2015 Ford Fusion engines compare:
  • 1.5L EcoBoost engine: 4.3 quarts, or 4.1 liters
  • 2.0L EcoBoost engine: 5.7 quarts, or 5.4 liters
  • 2.5L engine: 5.71 quarts, or 5.4 liters

What kind of oil does a 2015 Ford Fusion engine need?

The 2015 Ford Fusion’s engine oil requirements will also depend on its engine type. Using the wrong kind of engine oil could cause serious damage to your engine or other parts.
The 1.5L and 2.5L engines require premium synthetic blend or full synthetic 5W-20 engine oil, while the 2.0L engine requires premium synthetic blend or full synthetic 5W-30 engine oil.
Using the first oil type as an example, here’s a breakdown of what these numbers, known as your viscosity grade, mean. The “5” refers to the oil’s viscosity or thickness at colder temperatures before you’ve started your Ford Fusion’s engine, while the “20” refers to the oil’s viscosity after your engine has reached normal operating temperatures—around 212°F.
As you explore your engine oil options, the following are a few you could consider: 
  • Ford’s first pick: As a first choice, Ford recommends using
    Motorcraft engine oil
    with the correct specifications.
  • For high-mileage vehicles: If your Ford Fusion has truly gone the distance (more than  75,000 miles), a high-mileage engine oil like
    this option
    from STP could help improve performance and provide added protection.
  • A full synthetic option: For enhanced performance, consider a full synthetic engine oil like
    this option
    from Valvoline.
Whatever option you end up choosing for yourself, remember to verify it is a premium synthetic blend or full synthetic, has the correct viscosity grade, and has an API certification seal to show it meets the necessary quality standards.

How often to change oil on a 2015 Ford Fusion engine

When should you actually change the oil on your 2015 Ford Fusion? It depends. 
Generally, you should expect to change your 2015 Ford Fusion’s oil every 7,500 to 10,000 miles. As a more infrequent driver, you would want to change your engine oil at least every six months to make sure it stays functional and clear of debris.
However, more strenuous conditions could require you to change your engine oil even sooner. If you frequently drive on mountainous roads, off-road, or find yourself idling for extended periods in heavy traffic, you may need to change your oil as often as every 5,000 to 7,500 miles.
Since when you should actually change your oil can vary depending on different factors, it’s important to check your engine oil monthly. If it’s time for your 2015 Ford Fusion to receive an oil change, here are some signs you might notice:
  • Your oil life monitor indicator light has come on
  • Engine oil has become dark brown or black (as opposed to light brown)
  • Engine oil has a grainy texture, indicating excess debris buildup
  • You hear weird engine noises
  • You notice oil or burning scents coming from the engine
  • Worsened vehicle performance

How to change your oil and oil filter

If it’s finally time to change your Ford Fusion’s engine oil, you’ll need to gather some materials to get the job done. Those could include:
  • Socket wrench
  • Oil filter wrench
  • Funnel
  • Drain pan
  • Fresh engine oil
  • New oil filter
  • New washer for your drain bolt
  • Gloves
  • Towel(s) for cleanup
Once you have everything you need on hand, you can begin by running your engine for a few minutes, then shutting it off. This will heat up your engine oil and make it easier to drain. Then, prop open your hood, and here’s how you can proceed:
  • Remove the oil fill cap
  • Underneath the vehicle, remove the oil drain bolt and washer 
  • Allow the engine oil to empty into the drain pan
  • As the oil continues draining, remove the old oil filter and replace it with the new one
  • Replace the oil drain bolt using a new washer once the oil has finished draining
  • Refill the engine to the proper fill level with your new oil 
  • Replace the oil fill cap 
Next, let your engine run again for a few minutes to let the oil move around and look for any leaks. Once the engine has cooled down, you can use your dipstick to check the oil level again and add more if necessary.
One last step: remember to get rid of your old engine oil properly. It's a toxic substance, so you can't just flush it down the toilet or put it in the trash. You can drop off old engine oil for recycling in many cities. Some auto shops and dealerships also have places where you can do this.
