Capacity by Engine Option

Oil Change Interval

Subaru recommends an oil change interval of 6,000 miles or 6 months, whichever comes first, for all 2019 Outback models under normal driving conditions. However, your maintenance schedule may be accelerated if you frequently drive under "severe" conditions, which include:

• Repeated short trips (especially in freezing temperatures)
• Driving in dusty or dirty conditions
• Towing a trailer
• Driving in extreme heat or cold

Under these conditions, a shorter interval of 3,000 to 5,000 miles is advisable to ensure maximum engine protection.

Drain Plug Torque

The oil drain plug on a 2019 Subaru Outback should be torqued to 30.8 ft-lbs (41.8 Nm). It is highly recommended to replace the crush washer (part number 803916010) with every oil change to prevent leaks. Do not overtighten the drain plug, as this can damage the oil pan threads.

How to Change the Oil

A DIY oil change on a 2019 Outback is straightforward. The filter for the 2.5L engine is conveniently located on top of the engine, while the 3.6L filter is on the underside.

1. Warm up the engine for a few minutes to help the oil flow.
2. Safely raise the vehicle using ramps or jack stands.
3. Place a drain pan under the drain plug and remove the plug with a 14mm wrench.
4. Allow the old oil to drain completely.
5. Locate and remove the old oil filter. For the 2.5L engine, it is on the top-front of the engine. For the 3.6L, it is near the oil pan.
6. Wipe the filter mounting surface clean and apply a thin layer of new oil to the gasket of the new filter.
7. Install the new filter and hand-tighten it until snug, then give it an additional quarter-turn.
8. Reinstall the drain plug with a new crush washer and torque it to 30.8 ft-lbs.
9. Lower the vehicle and add the correct amount of new 0W-20 synthetic oil.
10. Start the engine, let it run for 30 seconds, then shut it off and re-check the oil level, adding more if necessary.

Common Issues / Tips

• Top-Mount Filter (2.5L): The location of the oil filter on the 2.5L engine makes for a clean and easy filter change. Place a rag around the base before loosening to catch any minor drips.
• Oil Consumption: Some FB25 engines have been known to consume oil between changes. It is wise to check your oil level every other fuel fill-up and top off as needed. Switching to a high-quality synthetic oil can sometimes help reduce consumption.
• Crush Washer: Do not reuse the drain plug crush washer. It is a single-use part designed to compress and seal. Reusing it is a common cause of slow oil leaks.
