The safest and most common method to drain oil from a car is from underneath the vehicle using a wrench to remove the drain plug, allowing the old oil to flow into a drain pan. This is a standard part of an oil change, which also involves replacing the oil filter. Always consult your vehicle's owner's manual for specific instructions and ensure the engine is warm but not hot to avoid burns. The process requires basic tools and careful disposal of the used oil.
Essential Tools and Materials
| Item | Purpose |
|---|---|
| Socket Wrench Set | To remove the drain plug, which is often a specific size (e.g., 13mm, 15mm). |
| Oil Drain Pan | A dedicated container to catch the used oil, typically with a capacity of 5-8 quarts. |
| New Oil Filter | Replacing the filter is crucial as it traps contaminants. |
| New Engine Oil | Use the type and viscosity (e.g., 5W-30) specified in your owner's manual. |
| Jack and Jack Stands | Essential for safely lifting and securing the vehicle. Ramps are a good alternative. |
| Gloves and Safety Glasses | Protects your skin and eyes from hot oil. |
First, run the engine for a few minutes to warm the oil, which helps it flow out more easily. Never work under a car supported only by a jack; always use jack stands or ramps for safety. Locate the drain plug on the bottom of the oil pan. Place the drain pan directly underneath it. Using the correct socket, turn the plug counterclockwise. Loosen it by hand for the last few turns, then quickly pull it away as oil will start flowing out immediately.
Once the oil stream slows to a drip, locate and remove the old oil filter. You may need an oil filter wrench if it's tight. Wipe the filter mounting surface on the engine clean. Apply a thin film of new oil to the gasket of the new filter and screw it on by hand until snug. Reinstall the drain plug, tightening it securely but avoid over-tightening. Finally, refill the engine with the correct amount of new oil through the oil filler cap under the hood.
Disposing of the used oil is a critical final step. Pour the oil from the drain pan into the empty new oil containers. Take it to an auto parts store, service station, or recycling center that accepts used oil—this service is almost always free.

Honestly, I just use rhino ramps. Drive the front wheels up, set the parking brake, and you're good to go. It feels way safer than messing with jacks. I stick the pan under the plug, crack it loose with a wrench, and let it rip. The key is having a pan with a pour spout. Makes dumping the old gunk into the empty bottles a clean job. Then I just drop it off at the auto store on my next errand run.

The most overlooked step is proper disposal. Used motor oil is a major pollutant. The process itself is straightforward: warm up the engine, drain, replace the filter, and refill. But the environmental responsibility comes after. Many DIYers forget that most auto parts stores are legally obligated to accept your used oil and filters for recycling at no cost. This closes the loop responsibly. Always store the oil in a sealed container for transport.
