Understanding Your 2013 Subaru Crosstrek’s Engine Oil Needs

The 2013 Subaru Crosstrek is powered by a 2.0-liter 4-cylinder Boxer engine (specifically the FB20 engine), which is known for its balance of efficiency and performance. This engine design, with its horizontally opposed pistons, requires precise oil levels and quality to operate smoothly. Unlike some engines that may tolerate slight overfilling, the Boxer engine is sensitive to oil volume, making it essential to follow the manufacturer’s specifications.

Subaru designed the Crosstrek with durability in mind, but that doesn’t mean it’s maintenance-free. Regular oil changes are the single most important thing you can do to extend your engine’s life. Oil lubricates moving parts, reduces friction, carries away heat, and helps keep the engine clean by suspending dirt and debris. Over time, oil breaks down and loses its effectiveness, which is why timely changes are critical.

When it comes to oil capacity, the 2013 Crosstrek has a total system capacity of 4.4 quarts (or 4.2 liters) when the oil filter is replaced. This number includes the oil in the engine, oil pan, and the new filter. If you’re only topping off oil between changes, you’ll typically add less—usually between 0.5 to 1 quart, depending on how low the level has dropped.

It’s also important to note that oil capacity can vary slightly depending on whether you’re performing a full drain-and-fill or just adding oil. Always refer to your owner’s manual or a trusted service guide for the most accurate information. And remember: using the right oil type and changing it on schedule is just as important as getting the quantity right.

How Much Oil Does a 2013 Subaru Crosstrek Take?

Let’s get straight to the point: the 2013 Subaru Crosstrek takes 4.4 quarts (4.2 liters) of oil when performing a complete oil change with a new filter. This is the official capacity listed in Subaru’s service documentation and confirmed by dealerships and certified mechanics.

Here’s how that breaks down:
– Engine oil pan: Approximately 4.0 quarts
– Oil filter: Holds about 0.4 quarts
– Total: 4.4 quarts

If you’re doing a DIY oil change, you’ll want to have at least five quarts of oil on hand. Why five? Because it’s common to spill a little during the process, and having an extra quart ensures you don’t come up short. Plus, you’ll likely need that fifth quart for topping off later or for future top-ups between changes.

It’s also worth noting that if you’re only adding oil (not doing a full change), you’ll rarely need more than 1 quart. The dipstick has “MIN” and “MAX” markings, and the difference between them is usually about 1 quart. So if your oil level is at the “MIN” line, adding 0.5 to 1 quart should bring it back to the safe range.

One mistake many people make is overfilling the engine. Adding too much oil can be just as harmful as not having enough. Excess oil can cause the crankshaft to whip the oil into a froth, reducing its ability to lubricate properly. This can lead to increased engine wear, reduced fuel efficiency, and even damage to seals and gaskets. Always double-check the level with the dipstick after adding oil and allow the engine to sit for a few minutes to let the oil settle.

Choosing the Right Oil for Your 2013 Subaru Crosstrek

Now that you know how much oil your Crosstrek needs, the next step is choosing the right type. Subaru has specific recommendations for the 2013 Crosstrek, and following them is key to maintaining engine performance and warranty coverage.

Recommended Oil Viscosity: 5W-30

Subaru officially recommends using 5W-30 motor oil for the 2013 Crosstrek. This viscosity grade is ideal for a wide range of temperatures, offering good cold-start protection in winter and stable performance in hot weather. The “5W” means the oil flows well at low temperatures (down to -25°F or -32°C), while the “30” indicates its thickness at operating temperature.

Using a different viscosity—like 10W-30 or 0W-20—can affect engine performance and fuel economy. For example, 0W-20 is thinner and may not provide adequate protection for the Boxer engine under heavy load, while 10W-30 might be too thick in cold climates, making cold starts harder on the engine.

Synthetic vs. Conventional Oil

Subaru allows the use of both synthetic and conventional oils, but there are benefits to going synthetic. Full synthetic 5W-30 oil offers better thermal stability, improved cold-flow properties, and longer service life compared to conventional oil. It also provides superior protection against sludge and deposits, which is especially helpful if you do a lot of short trips or drive in stop-and-go traffic.

That said, high-quality conventional oil is still acceptable if you change it more frequently. If you’re on a budget or prefer traditional oil, just make sure it meets the API (American Petroleum Institute) “SN” or later certification and is labeled as “energy-conserving.”

Many Crosstrek owners opt for synthetic blends or full synthetic oils like:
– Mobil 1 Extended Performance 5W-30
– Subaru Genuine Motor Oil 5W-30 (full synthetic)
– Pennzoil Platinum 5W-30
– Castrol EDGE 5W-30

These oils are widely available and trusted by mechanics and Subaru enthusiasts alike.

Oil Additives and Aftermarket Products

You might see products on the market claiming to “boost” oil performance with additives like friction reducers or seal conditioners. While some of these can be helpful in older engines, they’re generally unnecessary for a well-maintained 2013 Crosstrek. Modern motor oils already contain a balanced blend of additives designed to meet manufacturer specifications.

Adding extra additives can sometimes do more harm than good—especially if they interfere with the oil’s formulation or cause compatibility issues. Stick to high-quality oils from reputable brands and avoid mixing different types unless absolutely necessary.

How to Check and Change the Oil in Your 2013 Subaru Crosstrek

Performing regular oil checks and changes is one of the best ways to keep your Crosstrek running smoothly. Here’s a step-by-step guide to help you stay on top of it—whether you’re doing it yourself or just want to understand what your mechanic is doing.

Checking the Oil Level

Checking your oil is quick and easy, and you should do it at least once a month or before long trips. Here’s how:

1. Park your Crosstrek on level ground and turn off the engine. Wait 5–10 minutes to let the oil settle in the pan.
2. Open the hood and locate the yellow or orange dipstick handle near the front of the engine.
3. Pull out the dipstick, wipe it clean with a rag or paper towel, then reinsert it fully.
4. Pull it out again and check the oil level. The oil should be between the “MIN” and “MAX” marks. Ideally, it should be closer to “MAX.”
5. Also check the oil’s color and consistency. Fresh oil is amber and translucent. Dark, gritty, or milky oil may indicate contamination or the need for a change.

If the level is low, add oil in small increments (e.g., ½ quart at a time), rechecking with the dipstick each time. Never overfill.

Changing the Oil: DIY Step-by-Step

If you’re comfortable working on your car, changing the oil yourself can save you money and give you peace of mind. Here’s what you’ll need:
– 4.4 quarts of 5W-30 oil (plus a little extra)
– New oil filter (Subaru part #15208AA15A or equivalent)
– Oil filter wrench
– Socket wrench and 17mm socket (for drain plug)
– Oil drain pan
– Funnel
– Gloves and safety glasses
– Jack and jack stands (or ramps)

Steps:
1. Warm up the engine for a few minutes to help the oil flow more easily.
2. Lift the car securely using a jack and jack stands, or drive it onto ramps.
3. Place the drain pan under the oil drain plug (located on the bottom of the oil pan).
4. Loosen the drain plug with a 17mm socket and let the oil drain completely (about 10–15 minutes).
5. Remove the old oil filter using an oil filter wrench. Be prepared for some oil to spill.
6. Before installing the new filter, lightly coat the rubber gasket with fresh oil.
7. Screw on the new filter by hand until it seats, then give it an additional ¾ turn (do not overtighten).
8. Reinstall the drain plug and tighten it to 33 ft-lbs (use a torque wrench if possible).
9. Lower the car and add 4.4 quarts of oil through the filler cap on top of the engine.
10. Start the engine and let it run for 30 seconds, then turn it off and check for leaks.
11. Recheck the oil level with the dipstick and top off if needed.

Dispose of used oil and filters responsibly—most auto parts stores accept them for recycling.

When to Change the Oil

Subaru recommends changing the oil every 6,000 to 7,500 miles under normal driving conditions. However, if you frequently drive in “severe” conditions—such as:
– Short trips (less than 10 miles) in cold weather
– Stop-and-go traffic
– Towing or hauling heavy loads
– Driving in dusty or sandy environments
– Extreme heat or cold

—you should change the oil every 3,000 miles or every 3 months, whichever comes first.

Modern synthetic oils can last longer, but it’s still wise to follow Subaru’s guidelines. Over time, oil breaks down regardless of mileage, so time-based changes are just as important as distance-based ones.

Common Mistakes to Avoid When Changing Oil

Even experienced DIYers can make mistakes during an oil change. Here are some common pitfalls to watch out for:

Overfilling the Engine

As mentioned earlier, adding too much oil can cause foaming, reduced lubrication, and potential engine damage. Always use the dipstick to verify the level after adding oil. If you accidentally overfill, you may need to drain some oil or visit a mechanic to have it corrected.

Using the Wrong Oil Filter

Not all oil filters are created equal. While aftermarket filters may be cheaper, they can have lower filtration efficiency or poor sealing. Subaru OEM filters are designed specifically for your engine and ensure proper oil flow and pressure. If you use a cheap filter, it could collapse under pressure or leak, leading to oil loss and engine damage.

Not Replacing the Drain Plug Washer

The drain plug has a small copper or aluminum washer that creates a tight seal. Over time, this washer can deform or crack. Always replace it with a new one during each oil change to prevent leaks. Subaru part #11126AA010 is the correct washer for the 2013 Crosstrek.

Skipping the Oil Filter Change

Some people try to save money by reusing the old filter, but this is a false economy. The filter traps contaminants and loses efficiency over time. Reusing it can lead to restricted oil flow and increased engine wear. Always install a new filter with every oil change.

Ignoring Oil Leaks or Unusual Noises

After an oil change, check under the car for leaks. If you notice oil spots on your driveway or hear ticking or knocking sounds from the engine, it could indicate low oil pressure or improper installation. Address these issues immediately to avoid costly repairs.

Professional Oil Change vs. DIY: Which Is Right for You?

Deciding whether to change your own oil or take it to a professional depends on your comfort level, tools, and time.

Benefits of DIY Oil Changes
