How to Change Your Subaru Crosstrek's Oil at Home
Why Regular Oil Changes Matter
Oil keeps your Crosstrek's engine running smoothly. Over time, oil breaks down and collects dirt and debris. Changing your oil regularly helps your engine last longer and run better. It also helps maintain fuel efficiency and keeps engine parts from wearing out too quickly.
Most Subaru Crosstreks need an oil change every 6 months or 6,000 miles, whichever comes first. However, check your owner's manual for your specific vehicle's schedule. Some newer models may have longer intervals. Staying on top of oil changes is one of the most important things you can do to care for your vehicle.
What You'll Need
Before you start, gather all the items you'll need. Having everything ready makes the job go faster and smoother. You don't want to stop halfway through and search for a tool.
- New oil (check your owner's manual for the right type and amount)
- New oil filter
- Oil drain pan
- Wrench or socket set
- Oil filter wrench
- Jack and jack stands (to lift your vehicle safely)
- Ramps (an alternative to a jack)
- Funnel
- Rag or paper towels
- Safety glasses
- Gloves
The oil type matters for your Crosstrek. Your owner's manual lists the exact oil grade and viscosity your engine needs. Using the wrong oil can affect how your engine performs. The oil filter is also important—it removes contaminants from the oil as it circulates through your engine.
Step 1: Warm Up Your Engine
Start your Crosstrek and let it run for 2-3 minutes. Warm oil flows better than cold oil, which makes draining easier and more complete. You want the oil to be warm but not hot—hot oil can burn your skin.
After running the engine briefly, turn it off and wait about 5 minutes before you begin draining. This gives the oil time to drain back into the pan while still being warm enough to flow. Never work on a vehicle immediately after driving it, as the engine and oil will be too hot to handle safely.
Step 2: Lift Your Vehicle Safely
Park on a flat, level surface away from traffic. Use a jack to lift the front of your vehicle, or drive it onto ramps. Make sure the surface is solid and won't shift. Asphalt or concrete works best—avoid gravel or dirt.
Once lifted, place jack stands under the frame for safety. Never rely only on a jack to support your vehicle while you work underneath it. Jacks can fail or slip. Jack stands provide a backup safety measure. Position them on both sides of the front end. Double-check that everything is stable before you get under the vehicle.
Step 3: Remove the Drain Plug
Locate the drain plug under your engine. It's a bolt at the bottom of the oil pan. Position your drain pan underneath to catch the old oil. Use a wrench to loosen the plug by turning it counterclockwise. Once loose, unscrew it by hand carefully.
Be careful—the oil may still be warm and can burn your skin. Let all the old oil drain into the pan. This can take several minutes, so be patient. You want to get as much old oil out as possible. Once the dripping slows to just a few drops, the pan is mostly empty and you can move on to the next step.
Step 4: Replace the Drain Plug
Once the oil has drained completely, wipe the drain plug clean with a rag. Remove any old oil or debris stuck to it. A clean plug helps create a good seal when you reinstall it.
Screw the drain plug back in by hand first. This prevents you from cross-threading it. Once it's started, tighten it with a wrench by turning clockwise. Don't over-tighten—you only need it snug enough that it won't leak. Over-tightening can strip the threads or crack the pan.
Step 5: Change the Oil Filter
Locate the oil filter on your engine. It's usually a cylindrical canister mounted to the side of the engine. Use an oil filter wrench to loosen it by turning counterclockwise. Once loose, unscrew it by hand. Let any remaining oil drip into your drain pan.
Take the new filter and rub a thin layer of new oil around its rubber gasket. This helps create a good seal when installed. Screw the new filter on by hand until the gasket touches the engine, then turn it another three-quarter turn. Don't use the wrench for this final step—hand-tight is correct. A wrench can over-tighten the filter and cause problems when you need to remove it next time.
Step 6: Add New Oil
Lower your vehicle back to the ground using the jack or by backing off the ramps. Make sure it's stable and level before you proceed. Once on the ground, open the hood and locate the oil filler cap on top of the engine. It usually has an oil can symbol on it.
Twist the cap off and set it somewhere clean where you won't lose it. Place a funnel in the opening and pour in the correct amount of new oil. Check your owner's manual for how much your Crosstrek needs—this is usually between 3 and 5 quarts. Pour slowly to avoid spilling. Once you've added the oil, replace the oil filler cap and twist it on securely.
Step 7: Check Your Oil Level
Start your engine and let it run for about 30 seconds. This circulates the new oil through the engine and helps fill the new filter. Turn off the engine and wait 2-3 minutes for the oil to settle back into the pan.
Pull out the dipstick, wipe it clean with a rag or paper towel, and reinsert it fully until it seats. Pull it out again to check the level. The oil should be between the minimum and maximum marks on the stick. If it's low, add a little more oil and check again. If it's overfilled, you may need to drain some out. Getting the level right is important for engine health.
Step 8: Dispose of Old Oil
Never pour old oil down the drain or into the ground. Used oil is harmful to the environment and is illegal to dump in most places. Take your old oil to a recycling center, auto parts store, or service station that takes used oil.
Many places take used oil for free or for a small fee. Some auto parts stores even give you a discount on new oil if you bring in your old oil for recycling. Call ahead to find a location near you that accepts used oil. Proper disposal protects the environment and is the responsible thing to do.
When to Call a Professional
If you're not comfortable working under your vehicle or using a jack, take your Crosstrek to a mechanic. Oil changes are routine work that professionals do every day. There's no shame in leaving it to someone with experience.
You might also want professional help if you run into unexpected problems, like a stuck drain plug or a filter that won't come loose. A mechanic has specialized tools and experience to handle these situations safely. The cost of a professional oil change is reasonable and worth the peace of mind.

Frequently Asked Questions
How often should I change my Crosstrek's oil?
Most Subaru Crosstreks need an oil change every 6 months or 6,000 miles, whichever comes first. However, this can vary depending on your specific model year and driving habits. Always check your owner's manual for the exact interval recommended for your vehicle. Some newer Crosstreks may have longer intervals, so don't assume all models are the same.
What type of oil does my Crosstrek need?
The correct oil type for your Crosstrek is listed in your owner's manual. Different model years and engine types may require different oil grades and viscosities. Using the wrong oil can affect engine performance and longevity. Never guess—look it up in your manual or ask a mechanic if you're unsure. The oil bottle will have the specification clearly marked, so you can match it to what your manual says.
Can I change my oil if I don't have a jack and jack stands?
If you don't have a jack and jack stands, you can use ramps instead. Drive your Crosstrek slowly onto the ramps until the front end is elevated enough for you to work underneath. Make sure the ramps are on a flat, level surface and that the vehicle is secure before you get under it. You can also take your vehicle to a professional mechanic who has the proper equipment and experience to do the job safely.
How do I know if I've added too much oil?
After the engine runs and the oil settles, check the dipstick. The level should be between the minimum and maximum marks. If the oil is above the maximum mark, you've added too much. Overfilled oil can damage your engine by causing excessive pressure and foaming. If this happens, you'll need to drain some oil out. Use the dipstick to check the level again after removing oil to make sure it's in the correct range.
What should I do if the drain plug is stuck?
If the drain plug won't loosen, try using a longer wrench for more leverage. Apply steady pressure without jerking. You can also try tapping the wrench gently with a hammer to help break the seal. If it still won't budge, stop and take your vehicle to a mechanic. Forcing a stuck plug can strip the threads or break the pan, which is expensive to repair. A professional has the tools and experience to handle stuck plugs safely.
