Capacity by engine option

For the 2025 model year, the Subaru Forester is primarily offered with one engine option in most markets:

Oil change interval

Maintaining a consistent oil change schedule is crucial for the longevity of your 2025 Subaru Forester's engine.

• Normal Duty: Every 6,000 miles or 6 months, whichever comes first.
• Severe Duty: Every 3,000 miles or 3 months, whichever comes first. This applies if you frequently drive in conditions such as: short trips, stop-and-go traffic, extreme temperatures, dusty roads, towing, or mountainous terrain.

Drain plug torque

The oil drain plug on your 2025 Subaru Forester should be torqued to 30 ft-lbs (40 Nm). Always use a new crush washer to ensure a proper seal and prevent leaks. The OEM crush washer part number is typically 803916010, but it's always best to consult your dealer for the most current information.

How to change the oil

Changing the oil on your 2025 Subaru Forester is a straightforward process for the DIY enthusiast. Always ensure the vehicle is on a level surface, the engine is warm (but not hot), and you have proper safety equipment.

1. Gather Supplies: Collect your new oil, oil filter, drain pan, wrench for the drain plug, oil filter wrench, and a new crush washer.
2. Locate & Drain: Position the drain pan under the oil pan. Using the correct wrench, carefully loosen and remove the drain plug. Allow all the old oil to drain completely.
3. Replace Crush Washer & Reinstall Plug: Once drained, clean the drain plug, install a new crush washer, and hand-tighten the plug. Torque to 30 ft-lbs (40 Nm).
4. Remove & Replace Filter: Locate the oil filter. Use an oil filter wrench to remove the old filter. Apply a thin coat of new oil to the gasket of the new filter. Install the new filter and hand-tighten until snug, then turn an additional 1/2 to 3/4 turn (refer to filter instructions).
5. Add New Oil: Remove the oil filler cap. Carefully pour in approximately 4 quarts of new 0W-20 full synthetic oil. Start the engine and let it run for a minute to circulate the oil. Check for leaks around the drain plug and filter.
6. Check & Top Off: Turn off the engine and wait a few minutes for the oil to settle. Check the dipstick, adding more oil as needed until it reaches the 'full' mark. Do not overfill.
7. Reset Maintenance Light: Consult your owner's manual for instructions on resetting the oil maintenance light.

Common issues / tips

• Continuously Variable Transmission (CVT): The Forester utilizes a CVT. While separate from the engine oil, ensure you are not confusing CVT fluid checks/changes with engine oil. Consult your owner's manual for CVT service intervals.
• Subaru Oil Consumption: Some Subaru engines, particularly the FB family found in the Forester, have historically had discussions around higher-than-average oil consumption. While issues have largely been addressed in newer generations, it's always wise to monitor your oil level between changes, especially during the break-in period or if you notice any unusual oil levels.
• Proper Disposal: Always dispose of used engine oil and filters responsibly at a certified recycling center or auto parts store.
• Filter Location: The oil filter on the 2.5L engine is typically located on top of the engine, making it relatively easy to access for replacement.
