🔧 BRZ - Engine Oil & Oil Filter Change
Changing the oil and filter on your BRZ keeps the FA20 engine lubricated and helps prevent internal wear. You’ll drain the old oil, replace the crush washer and oil filter, then refill with the correct oil and verify the level.
Difficulty Level: Beginner | Estimated Time: 0.8-1.5 hours
⚠️ Safety & Precautions
- ⚠️ Work on a level surface and support the car on jack stands before going underneath.
- ⚠️ Hot oil can burn you; let the engine cool 10-20 minutes if it’s very hot.
- ⚠️ Use wheel chocks so the car can’t roll (manual transmission cars can move unexpectedly).
- ⚠️ Do not use the scissor jack for under-car work.
- 🔋 Battery disconnect is not required for an oil change.

🔩 Required Parts

- Engine oil (0W-20 full synthetic) - Qty: 6 quarts
- Oil filter - Qty: 1
- Oil drain plug crush washer - Qty: 1
📋 Before You Begin
- Park on level ground, put the shifter in 1st gear, and set the parking brake.
- Place wheel chocks behind both rear wheels.
- Warm the engine for 2-3 minutes, then shut it off. Warm oil drains faster.
- Open the hood and loosen the oil fill cap by hand (do not remove it yet).
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Lift and support the front of the car
- Use a floor jack (rated 2-ton minimum) to lift the front of the car at the front center jacking point.
- Set the car down onto jack stands (rated 2-ton minimum) placed at the approved front support points.
- Shake the car gently to confirm it is stable before going underneath.
Step 2: Remove the engine under cover (splash shield)
- Use a 12mm socket with a 3/8" drive ratchet to remove the bolts holding the under cover.
- Use a flat trim clip remover to pop out any plastic clips. (A trim clip remover is a small pry tool that removes plastic fasteners without breaking them.)
- Set the under cover and hardware aside so nothing gets lost.
Step 3: Drain the engine oil
- Place the drain pan (8-quart minimum) under the oil pan drain plug.
- Use a 14mm socket with a 3/8" drive ratchet to loosen the drain plug, then finish removing it by hand.
- Let the oil drain until it slows to an occasional drip (usually 5-10 minutes).
- Remove the old crush washer from the drain plug and install the new oil drain plug crush washer.
Step 4: Reinstall the drain plug
- Thread the drain plug in by hand first to avoid cross-threading.
- Use a 3/8" drive torque wrench (10-80 ft-lbs range) with a 14mm socket and Torque to 43 Nm (32 ft-lbs).
- If it doesn’t thread easily, stop and realign.
Step 5: Remove the old oil filter
- Move the drain pan under the oil filter (it will spill a little).
- Use an oil filter cup wrench 65mm 14-flute with a 3/8" drive ratchet to loosen the oil filter.
- Spin the filter off by hand and let it drain into the pan.
- Wipe the mounting surface with shop towels and make sure the old rubber gasket isn’t stuck to the engine.
Step 6: Install the new oil filter
- Put a thin film of new oil on the new filter’s rubber gasket using nitrile gloves.
- Install the filter by hand until the gasket touches, then tighten an additional 3/4 turn by hand.
- If you prefer using a torque wrench: use the oil filter cup wrench 65mm 14-flute and Torque to 12.5 Nm (9 ft-lbs).
Step 7: Reinstall the engine under cover
- Reposition the under cover.
- Reinstall bolts using a 12mm socket and 3/8" drive ratchet.
- Reinstall clips using a flat trim clip remover (press them in until fully seated).
Step 8: Refill with new engine oil
- Lower the car off the jack stands using the floor jack (rated 2-ton minimum).
- Remove the oil fill cap and insert a funnel.
- Pour in about 5.4 quarts of 0W-20 full synthetic (the FA20 is typically ~5.4 qt with filter).
- Reinstall the oil fill cap by hand.
Step 9: Check for leaks and set the oil level
- Start the engine and let it idle for 30-60 seconds.
- Shut the engine off and wait 3-5 minutes for oil to drain back into the pan.
- Pull the dipstick, wipe it with shop towels, reinsert fully, then check the level.
- Add small amounts using the funnel until the oil is at the full mark (do not overfill).
- Look underneath for leaks at the drain plug and around the oil filter.
✅ After Repair
- Recheck the dipstick level after your first short drive (5-10 minutes).
- Dispose of used oil and the filter at a recycling center or auto parts store that accepts waste oil.
- If your BRZ maintenance reminder is enabled, reset it in the multi-function display: Settings > Maintenance > Engine Oil > Reset (wording may vary slightly).
