All 2022 Subaru Forester models come equipped with the same 2.5L SUBARU BOXER engine. Therefore, all trims share the same oil capacity.

Oil Change Interval

Subaru recommends adherence to the following oil change intervals for your 2022 Forester:

• Normal Duty: Every 6,000 miles or 6 months, whichever comes first.
• Severe Duty: Every 3,000 miles or 6 months, whichever comes first. This applies if you frequently drive under conditions such as: short trips (especially in cold weather), extensive idling, dusty conditions, towing, or mountainous terrain.

Regular oil changes are crucial for the longevity and performance of your Boxer engine, especially given its unique design characteristics.

Drain Plug Torque

The oil drain plug on your 2022 Subaru Forester should be torqued to 30.8 ft-lbs (41.7 Nm). Always use a new crush washer (gasket) with each oil change to ensure a proper seal and prevent leaks. The OEM crush washer part number is typically 803916010.

How to Change the Oil

1. Warm Up Engine: Drive the vehicle for a few minutes to warm the oil, allowing it to drain more easily.
2. Lift and Secure: Safely lift the front of the vehicle using a jack and secure it with jack stands. Always use wheel chocks on the rear wheels.
3. Locate Drain Plug: Place a suitable drain pan beneath the oil pan. Locate the 17mm drain plug on the bottom of the oil pan.
4. Drain Oil: Carefully remove the drain plug, allowing the old oil to drain completely. Be mindful that the oil may be hot.
5. Replace Crush Washer & Reinstall Plug: Install a new crush washer on the drain plug and reinstall it into the oil pan. Torque to 30.8 ft-lbs (41.7 Nm).
6. Locate & Remove Oil Filter: The oil filter is typically located on top of the engine near the front, making it relatively easy to access. Place a rag or paper towels around the filter base to catch any drips and remove it counter-clockwise using an oil filter wrench.
7. Prepare New Filter: Apply a thin film of new oil to the rubber gasket of the new oil filter.
8. Install New Filter: Hand-tighten the new oil filter until it seats, then turn an additional 3/4 to 1 full turn. Do not overtighten.
9. Add New Oil: Lower the vehicle and add 4.0 quarts of new 0W-20 oil through the engine
