The Drain and Fill Process
Now for the main event! Follow these steps carefully for a smooth oil change.
- Locate Drain Plug: Position your oil drain pan directly under the oil pan drain plug. It’s usually on the bottom of the engine oil pan, facing the rear of the car.
- Remove Drain Plug: Using your 17mm socket wrench, loosen and carefully remove the drain plug. Be prepared for hot oil to stream out immediately. Allow all the old oil to drain completely. This can take 10-15 minutes.
- Replace Drain Plug Washer: Once the oil has fully drained, clean the drain plug. Install a new crush washer on the drain plug. This is crucial for preventing leaks.
- Reinstall Drain Plug: Thread the drain plug back into the oil pan by hand to avoid cross-threading. Once finger-tight, use your wrench to tighten it. The recommended torque spec is usually around 29 lb-ft (39 N-m). Do not overtighten! Overtightening can strip the oil pan threads, leading to a much more expensive repair.
- Locate and Remove Old Oil Filter: The oil filter on your 2015 Civic 1.8 is typically located on the front of the engine, below the exhaust manifold. Place your drain pan underneath it, as some residual oil will drip out. Use your oil filter wrench to loosen and remove the old filter.
- Prepare New Oil Filter: Take your new oil filter. Apply a thin film of fresh engine oil to the rubber gasket of the new filter. This helps create a good seal and makes future removal easier.
- Install New Oil Filter: Thread the new oil filter onto the engine by hand. Once the gasket makes contact with the engine block, tighten it another 3/4 to 1 full turn by hand. Do not use an oil filter wrench to tighten the filter, as this can overtighten it and cause leaks or damage. Hand-tight is sufficient.
- Add New Oil: Lower your car safely off the jack stands. Open the hood and remove the oil fill cap (usually marked with an oil can symbol). Place your funnel in the oil fill opening. Slowly pour in approximately 3.5 quarts of your new 0W-20 synthetic oil.
- Check Oil Level: Wait a few minutes for the oil to settle in the pan. Pull out the dipstick, wipe it clean, reinsert it fully, and pull it out again. The oil level should be between the two marks on the dipstick.
- Start the Engine: Start the engine and let it run for about a minute. Check for any leaks around the drain plug and oil filter. The oil pressure light on your dashboard should turn off.
- Final Oil Level Check: Turn off the engine and wait another 5-10 minutes for the oil to drain back into the pan. Re-check the dipstick. Add small amounts of oil (1/4 quart at a time) if needed, until the level is at or just below the upper mark on the dipstick. Do not overfill.
- Clean Up: Wipe up any spilled oil and properly dispose of your used oil.
