Changing Oil in the 2023 Subaru Outback: Step-by-Step Guide

Changing the oil in your Subaru Outback is a straightforward process. Here’s a step-by-step guide to ensure you do it right, maintaining your vehicle’s health and efficiency.

2023 Subaru Outback 2.5 Oil Change Guide

Subaru recommends changing oil every 6,000 miles, but it’s smart to do it a little early, around the 5,000-mile mark.

When changing the oil yourself, be sure to use Subaru-approved parts:

  • Oil: SAE 0W-20 full synthetic
  • Oil filter: Subaru part #15208AA15A
  • Drain bolt gasket: Subaru part #8039160100

This helps ensure the oil change goes smoothly and prevents any leaks or other issues from using off-brand parts.

Step-by-Step DIY Oil Change

Below are the key steps:

1. Warm Up the Engine

Let the engine run for a few minutes before starting the oil change – this lets the oil flow freely and makes it easier to drain.

2. Prepare Tools & Supplies

Gather all the necessary tools and supplies, including oil filter wrench, drain pan, jack and jack stands, etc. Safety first!

3. Access the Drain Plug

The drain plug is located under a plastic cover on the bottom of the engine. Remove the cover to access it.

4. Drain the Old Oil

Place the drain pan underneath and use a 14mm wrench to loosen the plug. Let the old oil completely drain out.

5. Replace Drain Bolt & Gasket

Once drained, replace the drain bolt with a new gasket (Part #8039160100) to prevent leaks.

6. Remove Old Oil Filter

Use an oil filter wrench to loosen and remove the old filter. Some mess is inevitable here.

7. Install New Oil Filter

Lubricate the gasket on the new filter, then install it by hand tightening.

8. Add New Oil

Pour in 5.1 quarts of 0W-20 synthetic oil through the fill cap. Check the level periodically with the dipstick.

9. Run & Inspect

Start the engine, let it run for a minute, then check for any leaks. Top off oil if needed.

And that’s it! With the right prep and Subaru OEM parts, DIY oil changes on the 2.5L Forester are straightforward. Just follow the steps above and refer to your owner’s manual.

Engine Oil Consumption

It is normal for engine oil to be consumed during driving. The amount used can vary based on driving conditions like transmission type, driving style, terrain, and temperature. More oil may be consumed in these situations, requiring refills between service intervals:

  • When the engine is new and still being broken in
  • Using lower quality or incorrect viscosity oil
  • Frequent engine braking
  • Extended periods at high engine speeds or heavy loads
  • Towing a trailer (Outback/Subaru Outback Wilderness models)
  • Extended idling
  • Stop-and-go traffic and heavy traffic conditions
  • Severe thermal conditions
  • Frequent acceleration and deceleration

If you are driving under demanding conditions, you should check your oil at least every other time you fuel up and change it more frequently. It’s important to note that oil consumption can differ between drivers, even when driving the same vehicle.

If you think your oil consumption is excessive, contact your Subaru retailer to conduct a consumption test under controlled conditions.
