🔧 Prius - Engine Oil & Oil Filter Replacement

On your Prius, an oil change means draining the old engine oil and replacing the cartridge-style oil filter element inside the filter housing. Fresh oil and a new filter protect the engine and help it run efficiently, especially on hybrids that do lots of start/stop driving.

Difficulty Level: Beginner | Estimated Time: 1.0-1.5 hours

⚠️ Safety & Precautions

• ⚠️ Work on a level surface and support the car with jack stands—never rely on a jack alone.
• ⚠️ Make sure the car is OFF (not in READY). Keep the key/fob away so it can’t power on.
• ⚠️ Engine oil can be hot. Let it cool 15–30 minutes before draining.
• ⚠️ Wear gloves and safety glasses to avoid burns and splashes.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the hood and remove the oil fill cap

• Open the hood and remove the oil fill cap (by hand) on top of the engine.
• This helps the oil drain faster.

Step 2: Lift and secure the front of the car

• Drive onto drive-on ramps, or lift with a floor jack and place the car on jack stands.
• Place wheel chocks behind the rear tires.

Step 3: Open the lower engine cover access panel

• Slide the drain pan under the engine area.
• Use a 10mm socket and 3/8" ratchet to remove the small access door fasteners in the under cover (some fasteners may be clips).
• If you have plastic clips, gently pry them with a small flathead screwdriver to avoid breaking them.

Step 4: Drain the engine oil

• Locate the oil drain plug on the bottom of the oil pan.
• Use a 14mm socket with a 3/8" ratchet to loosen and remove the drain plug.
• Let the oil drain completely into the drain pan (usually 5–10 minutes).
• Remove the old drain plug gasket/washer and install the new one.
• Reinstall the drain plug by hand first, then tighten with a torque wrench: Torque to 40 Nm (30 ft-lbs).

Step 5: Replace the oil filter element (cartridge style)

• Locate the oil filter housing (a round cap-style housing near the drain plug area).
• Use the 64mm 14-flute oil filter cap wrench (specialty) with a 3/8" ratchet to loosen the filter housing cap.
• Once loose, finish unscrewing by hand and lower it carefully—oil will spill.
• Pull the old filter element out of the housing by hand.
• Use a pick tool (specialty) to remove the old O-ring(s) from the cap, then install the new O-ring(s) from the filter kit.
• Reinstall the new filter element into the housing.
• Screw the housing cap back on by hand to avoid cross-threading, then tighten with a torque wrench: Torque to 25 Nm (18 ft-lbs).
• Lightly oil the new O-ring first.

Step 6: Reinstall the access panel

• Reposition the under cover access door.
• Use the 10mm socket and 3/8" ratchet to reinstall bolts, and press clips back in by hand.

Step 7: Refill with oil

• Lower the car back to the ground (remove jack stands or back off the ramps).
• Place a funnel in the oil fill opening.
• Pour in SAE 0W-20 full synthetic, starting with about 4.0 quarts.
• Reinstall the oil fill cap (by hand).

Step 8: Start, check for leaks, then set the oil level

• Start the car normally and let it run for 30–60 seconds.
• Turn the car OFF and look underneath for leaks at the drain plug and filter housing.
• Wait 5 minutes, then check the dipstick and top off slowly until it reaches the full mark.
• Total fill is typically about 4.4 quarts with a filter change, but always follow the dipstick.

Step 9: Reset the oil maintenance reminder

• Turn the car to ON (not READY) and use the steering wheel controls.
• Try this path on the multi-information display: Settings (gear icon) > Vehicle Settings > Maintenance System > Oil Maintenance > Reset > Yes.
• If your menu looks different, tell me what options you see under Settings, and I’ll give the exact path.

✅ After Repair

• Recheck for leaks after your first short drive.
• Verify the oil level again after the engine has been off for 5 minutes.
