Capacity by Engine Option
The 2025 Outback is available with two engine options, each with slightly different oil capacities.
| Engine | Oil Capacity (with filter) |
|---|---|
| 2.5L 4-cylinder | 4.8 quarts / 4.5 liters |
| 2.4L Turbo 4-cylinder | 5.1 quarts / 4.8 liters |
Oil Change Interval
Subaru recommends an oil change interval of 6,000 miles or 6 months, whichever comes first, for normal driving conditions. However, if you frequently drive in "severe duty" conditions, you should shorten this interval to 3,000 miles or 3 months. Severe duty includes:
- Towing
- Frequent short trips in cold weather
- Driving in dusty or muddy conditions
- Extended idling
Drain Plug Torque
The oil drain plug on the 2025 Subaru Outback should be torqued to 31 ft-lbs (42 Nm). It is highly recommended to use a new crush washer with every oil change to prevent leaks. The Subaru part number for the crush washer is 803916010.
How to Change the Oil
Changing the oil in your 2025 Outback is a straightforward process that can be done at home with a few basic tools.
- Warm up the engine: Run the engine for a few minutes to warm up the oil, which will help it drain more easily.
- Lift the vehicle: Safely lift the front of the vehicle with a jack and support it with jack stands.
- Drain the oil: Place a drain pan under the oil drain plug, and use a wrench to remove the plug. Allow the oil to drain completely.
- Replace the oil filter: The location of the oil filter will depend on your engine. On the 2.5L, it's on top of the engine. On the 2.4L Turbo, it's on the bottom. Remove the old filter, and make sure the gasket comes off with it. Apply a thin layer of new oil to the gasket of the new filter before screwing it on.
- Refill with new oil: Replace the drain plug (with a new crush washer) and torque it to spec. Then, refill the engine with the correct amount of new 0W-20 oil.
- Check for leaks: Start the engine and let it run for a minute, checking for any leaks around the drain plug and oil filter. Then, turn the engine off and check the oil level on the dipstick, adding more oil if necessary.
Common Issues / Tips
- Filter Location: Be aware that the oil filter is in different locations on the two engines. The 2.5L has a top-mount filter which is very easy to access, while the 2.4L Turbo has a bottom-mount filter that requires getting under the vehicle.
- Fumoto Valve: Many Subaru owners install a Fumoto oil drain valve to make future oil changes quicker and cleaner. This valve replaces the stock drain plug and allows you to drain the oil with the flip of a lever.
- Oil Consumption: Some Subaru engines have been known to consume a small amount of oil between changes. It's a good practice to check your oil level every few weeks and top it off as needed.
