๐ฉ Required Parts
HowToo sells all the parts you need for this repair:
- Engine oil (0W-20 full synthetic) - Qty: 4 quarts
- Oil filter - Qty: 1
- Drain plug crush washer - Qty: 1
๐ Before You Begin
- Park your Fit on level ground, set the parking brake, and place wheel chocks behind the rear tires.
- Warm the engine for 2-3 minutes, then shut it off. Warm oil drains faster.
- Open the hood and loosen/remove the oil filler cap (this helps oil drain smoothly).
- Raise the front with a floor jack and place it securely on jack stands at the front lift points.
๐จ Step-by-Step Instructions
Follow these steps in order:
Step 1: Drain the old engine oil
- Put on nitrile gloves and safety glasses.
- Place the drain pan under the oil pan drain plug.
- Use a 17mm socket and 3/8" 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).
Step 2: Reinstall the drain plug with a new crush washer
- Wipe the drain plug and the oil pan sealing area with shop towels.
- Install a new drain plug crush washer onto the drain plug.
- Thread the drain plug in by hand first (prevents cross-threading).
- Use a torque wrench with a 17mm socket and Torque to 39 Nm (29 ft-lbs).
Step 3: Remove the oil filter
- Move the drain pan under the oil filter area (the filter will spill oil when it comes off).
- Use the oil filter wrench (65mm 14-flute) to loosen the filter, then spin it off by hand.
- Make sure the old rubber gasket (seal) came off with the old filter. If it stuck to the engine, peel it off by hand.
- Double-gasket = big oil leak.
Step 4: Install the new oil filter
- Put a light film of new oil on the new filterโs rubber gasket using a gloved finger.
- Spin the new filter on by hand until the gasket touches the engine surface.
- Tighten the filter an additional 3/4 turn by hand after gasket contact.
- If using a torque method: use the torque wrench and oil filter wrench and Torque to 12 Nm (9 ft-lbs).
Step 5: Refill with new oil
- Insert a funnel into the oil fill opening.
- Pour in about 3.5 quarts of 0W-20 first (your Fit is typically about 3.7 quarts with filter, but start slightly low).
- Reinstall the oil filler cap by hand.
Step 6: Start, check for leaks, then set the oil level
- Start the engine and let it idle for 30-60 seconds.
- Shut the engine off and look underneath with a flashlight for leaks at the drain plug and oil filter.
- Wait 2-3 minutes, then check the dipstick, wipe, reinsert, and recheck.
- Add oil in small amounts (about 0.1-0.2 quart at a time) until the level is near the upper mark.
Step 7: Reset the Maintenance Minder (Oil Life)
- Use one of these methods (your Fit may have either):
- Method A (instrument cluster/MID): use the steering wheel buttons to go to Settings > Vehicle Settings > Maintenance Info, select Oil Life, then choose Reset.
- Method B (Display Audio screen): turn ignition ON, then on the screen select Home > Settings > Vehicle > Maintenance Info, choose Oil Life, then Reset.
โ After Repair
- ๐ Recheck the dipstick level after a short 5-10 minute drive and top off if needed.
- ๐ Confirm there are no drips under the drain plug or oil filter.
- ๐งพ Record the mileage/date for your next service.
- โป๏ธ Pour old oil into a sealed container and take it (and the old filter) to an oil-recycling drop-off (most auto parts stores accept it).
