Capacity by Engine Option

Oil Change Interval

Regular oil changes are crucial for the longevity of your Crosstrek's engine. Subaru recommends the following intervals:

• Normal Duty: Every 6,000 miles or 6 months, whichever comes first.
• Severe Duty: Every 3,000 miles or 3 months, whichever comes first. Severe duty conditions include frequent short trips, driving in dusty conditions, towing, or extensive idling.

Always refer to your 2025 Subaru Crosstrek owner's manual for the most accurate and up-to-date maintenance schedule.

Drain Plug Torque

The oil drain plug on your 2025 Subaru Crosstrek should be torqued to 30 ft-lbs (41 Nm). Always replace the crush washer with a new one each time you perform an oil change to ensure a proper seal and prevent leaks. The crush washer is typically a 14mm aluminum or copper washer.

How to Change the Oil

Changing your own oil can be a rewarding and cost-effective maintenance task. Here's a general overview of the steps:

1. Warm up the engine: Drive the vehicle for a few minutes to bring the oil to operating temperature, which helps it drain more easily.
2. Lift and secure: Park on a level surface, engage the parking brake, and safely lift the front of the vehicle using a jack and secure it with jack stands.
3. Locate and drain: Place a drain pan beneath the oil pan. Locate the oil drain plug, remove it carefully (watch out for hot oil), and allow all the oil to drain completely.
4. Replace drain plug: Once drained, reinstall the new crush washer and tighten the drain plug to the specified 30 ft-lbs (41 Nm).
5. Remove old filter: Locate the oil filter, place the drain pan underneath, and carefully unscrew it. Be prepared for some oil to spill.
6. Install new filter: Apply a thin film of new oil to the rubber gasket of the new filter. Screw on the new filter by hand until snug, then tighten an additional 3/4 to 1 full turn (or as per filter manufacturer's instructions).
7. Add new oil: Lower the vehicle. Remove the oil fill cap and add the recommended 4.2 quarts of new 0W-20 oil.
8. Check level: Start the engine and let it run for a minute to circulate the oil. Shut it off, wait a few minutes, then check the oil level with the dipstick. Add more oil if necessary, but do not overfill.
9. Dispose: Properly dispose of the old oil and filter at an authorized recycling center.

Common Issues / Tips

• CVT Longevity: While not directly related to oil, proper engine oil maintenance supports the overall health of the powertrain, including the Continuously Variable Transmission (CVT) that is standard on the Crosstrek. Regular, high-quality oil changes help ensure the engine is running optimally, reducing stress on other components.
• Subaru Oil Consumption: Some Subaru engines, particularly previous generations, have been known to consume a small amount of oil between changes. While less prevalent in newer models, it's always a good practice to periodically check your oil level between scheduled changes, especially if you drive under severe conditions.
• AWD System: The Crosstrek's Symmetrical All-Wheel Drive system doesn't require special engine oil, but maintaining proper engine lubrication is vital for overall vehicle performance and efficiency.
• Genuine Subaru Filters: While aftermarket filters are available and perform well, many Subaru enthusiasts and technicians recommend using genuine Subaru oil filters due to their specific design and bypass valve settings engineered for Subaru engines. Consult your dealer if you are unsure about filter compatibility.
