How do you change oil fluid?
Drain the old oil, replace the filter, and refill with fresh oil, then check the level and for leaks. This article provides a practical, step-by-step guide to changing engine oil on most modern cars, including what you need, how to do it safely, and how to dispose of used oil responsibly.
What you’ll need
Before you start, gather the supplies and tools you’ll need so you can complete the job without interruptions. This list covers basic items common to most oil changes.
- New engine oil of the grade and quantity specified in your owner's manual
- New oil filter (and a new washer for the drain plug if your vehicle requires one)
- Oil drain pan with a capacity appropriate to your oil volume
- Funnel to pour oil without spills
- Ratcheting socket wrench or wrench to fit the drain plug
- Oil filter wrench (optional but helpful)
- Jack and jack stands or ramps for elevated access (on a level surface)
- Wheel chocks
- Gloves and safety glasses
- Rags or shop towels
- Sealed container for used oil
- Owner’s manual for specifications
With the right supplies on hand, you’re set to perform a clean and efficient oil change. Keep used oil out of the environment and wipe up any spills promptly to minimize exposure.
Step-by-step process
The following steps cover a standard oil change you can perform on most gasoline cars. Your vehicle may differ slightly, so consult the owner’s manual for exact specs and torque values.
- Prepare the vehicle: Park on level ground, engage the parking brake, and if you’ll lift the car, use a jack and secure with jack stands. Turn off the engine and let it cool briefly, then locate the oil filler cap and the drain plug.
- Drain the old oil: Place the drain pan under the oil drain plug. Use the correct size wrench to loosen the drain plug, and carefully allow the oil to drain completely into the pan. Once draining slows, snug the plug back in place, but do not overtighten.
- Replace the oil filter: Move the drain pan under the filter. Remove the old filter, knowing that some oil will spill. Lightly oil the gasket on the new filter and install it by hand, then follow the manufacturer’s guidance for any additional torque or turns.
- Refill with fresh oil: Remove the oil filler cap. Using a funnel, pour in the amount specified for your engine. Add a little at a time and check the level with the dipstick to avoid overfilling.
- Check for leaks and top off: Start the engine and run for 1–2 minutes, then turn it off and wait a moment. Check under the vehicle for leaks, and recheck the dipstick. Add oil if the level is below the full mark.
- Dispose of old oil and filter properly: Transfer used oil and the old filter to a certified recycling facility or auto shop. Do not pour used oil down the drain. Recycle the oil filter according to local guidelines.
Following these steps will help ensure a clean, effective oil change and protect your engine while supporting responsible waste management. Always refer to your owner’s manual for your car’s exact oil capacity and recommended specifications.
Safety, disposal and environmental notes
Oil changes carry risks if rushed or done improperly. Work on a level surface, never rely on a jack alone to support a raised vehicle, wear gloves, and protect your eyes from splashes. Collect used oil in a sealed container and bring it to a recycling facility or service center that accepts automotive oil. Oil filters should be recycled or disposed of according to local regulations.
Summary
In brief: drain the old oil, replace the filter, and refill with fresh oil, then verify the level and check for leaks. With the right tools, careful preparation, and proper disposal, you can complete a safe, effective oil change in under an hour and extend the life of your engine.
