Step-by-Step Guide: How to Change Car Oil and Filter Like a Pro

With your vehicle safely secured, you’re ready to tackle the main task. Follow these steps carefully.

This detailed guide will ensure you don’t miss any critical part of the process.

1. Draining the Old Oil

  1. Locate the Drain Plug: It’s usually a large bolt on the bottom of the oil pan.

    Consult your owner’s manual if you can’t find it.

  2. Position the Drain Pan: Place your oil drain pan directly beneath the drain plug.

    Ensure it’s centered and has enough capacity.

  3. Remove the Drain Plug: Use the correct size wrench to loosen the drain plug.

    Once loose, carefully unscrew it by hand.

    Be prepared for hot oil to flow out immediately.

  4. Let it Drain Completely: Allow all the old oil to drain into the pan.

    This can take 10-15 minutes.

    The stream will eventually slow to a drip.

  5. Inspect and Replace Washer: While the oil drains, inspect the drain plug.

    Replace the old crush washer or gasket with a new one.

    This new washer is crucial for a leak-free seal.

  6. Reinstall Drain Plug: Once drained, clean the drain plug and the area around the drain hole.

    Thread the drain plug back in by hand to avoid cross-threading.

  2. Prepare for Spills: Place a small secondary drain pan or some rags under the filter.

    Some residual oil will inevitably spill when removed.

  3. Remove the Old Filter: Use your oil filter wrench to loosen the filter.

    Once loose, unscrew it by hand.

    Be careful, as it will be full of old oil.

  4. Prepare the New Filter: Before installing the new spin-on filter, apply a thin film of new engine oil to the rubber gasket on the new filter.

    This helps create a good seal and prevents the gasket from sticking or tearing.

    For cartridge filters, ensure all old O-rings are removed and new ones (usually supplied with the filter) are installed and lubricated.

  5. Install the New Filter: Hand-tighten the new filter onto its mounting stud until the gasket makes contact.

    Then, turn it an additional 1/2 to 3/4 turn by hand (or as specified by the filter manufacturer).

    Do not overtighten with a wrench, as this can damage the filter or its housing.

3. Adding Fresh Oil

The final step in our how to change car oil and filter guide is crucial for proper lubrication.

  1. Lower the Vehicle: Carefully raise the vehicle with the jack, remove the jack stands, and then fully lower the car to the ground.

  2. Locate Oil Fill Cap: It’s usually on top of the engine and clearly marked.

  3. Add New Oil: Place the funnel into the oil fill hole.

    Slowly pour the recommended amount of new engine oil into the engine.

    Refer to your owner’s manual for the exact capacity.

  4. Check Oil Level: After pouring, wait a few minutes for the oil to settle in the pan.

    Remove the dipstick, wipe it clean, reinsert it fully, then remove it again.

    The oil level should be between the “min” and “max” marks.

    Add more oil if needed, but avoid overfilling.

  5. Replace Oil Fill Cap: Securely tighten the oil fill cap.

Post-Change Checks and Common Troubleshooting Tips

Your work isn’t done after the oil is in. A few final checks ensure everything is perfect.
