2016 Subaru Outback 2.5L Standard Oil Change Guide

Performing a standard oil change on your 2016 Subaru Outback 2.5L is a straightforward, moderate-difficulty job. The #1 cause of comebacks is not replacing the drain plug crush washer, which can lead to leaks. Also, be sure to use the correct oil type and quantity to avoid engine damage.

What you'll need

• Tools:

  • 17mm socket or wrench (for drain plug)
  • Oil filter wrench (cap or band type depending on filter)
  • Oil drain pan
  • Funnel
  • Ratchet and extension (if needed)
  • Gloves and rags

• Parts & consumables:

  • 0W-20 full synthetic engine oil (about 4.8 quarts with filter change)
  • OEM or quality aftermarket oil filter (specific to 2016 Outback 2.5L)
  • New crush washer for drain plug

• Optional:

  • Oil filter socket (if your filter requires a specific size)
  • Jack and jack stands or ramps (if clearance is tight)

Step-by-step

1. Warm up the engine for a few minutes, then shut it off. Warm oil drains faster but avoid burns.

2. Safely raise the vehicle if needed and secure on jack stands or ramps.

3. Place the drain pan under the oil drain plug on the oil pan.

4. Using the 17mm socket, carefully loosen and remove the drain plug. Let all oil drain out.

5. Remove the old crush washer from the drain plug and discard.

6. While oil drains, locate and remove the oil filter using the filter wrench.

7. Prepare the new oil filter: apply a thin coat of new engine oil to the rubber gasket.

8. Install the new oil filter by hand until gasket contacts the base, then tighten another 3/4 turn. Do not overtighten.

9. Clean the drain plug and install a new crush washer. Reinstall the drain plug and torque to spec.

10. Lower the vehicle if raised.

11. Remove the oil fill cap on top of the engine and add about 4.8 quarts of 0W-20 synthetic oil using a funnel.

12. Replace the oil fill cap.

13. Start the engine and check for leaks at the drain plug and oil filter.

14. Let the engine run for a minute, then shut off and wait a few minutes.

15. Check the oil level with the dipstick and add oil if needed to reach the full mark.

16. Reset the oil maintenance light via the instrument cluster menu.

Specs & resets

• Drain plug torque: 25 ft-lbs (34 Nm)
• Oil filter tightening: Hand tight + 3/4 turn (no torque spec usually)
• Engine oil type: SAE 0W-20 full synthetic
• Oil capacity with filter: 4.8 quarts (4.5 liters)
• Reset oil life monitor: Turn ignition ON (engine off), press and hold trip reset button until oil light blinks and resets (consult owner's manual for exact method)

Common mistakes to avoid

• Reusing crush washer: Always replace to prevent leaks.
• Overtightening oil filter: Hand tight + 3/4 turn only to avoid damage.
• Using wrong oil viscosity: Stick to 0W-20 synthetic as per Subaru spec.
• Not checking oil level after fill: Always verify with dipstick.
• Not resetting oil life monitor: Causes inaccurate maintenance reminders.

When to stop and get help

• Drain plug threads are stripped or damaged.
• Oil filter housing is cracked or damaged.
• Oil leaks persist after tightening.
• Unable to reset oil life monitor.
• Severe rust or corrosion on drain plug or oil pan.

If you want, I can guide you through the oil life monitor reset procedure or help with specific filter recommendations.

For your 2016 Subaru Outback 2.5L, the 0W-20 oil must meet the following specifications to ensure proper engine protection and warranty compliance:

• API Certification: At least API SN or newer (SN Plus or SP preferred)
• ILSAC Standard: GF-5 or GF-6 approved
• Synthetic: Full synthetic oil is recommended for optimal performance and protection

Subaru specifically recommends using oils that meet these standards to maintain fuel economy, cold start performance, and engine longevity.

Avoid:

• Using conventional (non-synthetic) oil
• Using oils with lower viscosity or that don't meet API/ILSAC standards
• Using oils with additives not approved by Subaru (e.g., certain friction modifiers)

Stick to high-quality brands that clearly state these certifications on the label.

If you want, I can recommend some OEM or aftermarket oil brands that fit these specs.
