Never work under a vehicle supported only by a jack. Use sturdy jack stands placed on a flat, level surface to secure your vehicle. Chock the wheels that remain on the ground to prevent any unintended movement, adding an extra layer of security before you get underneath.
Engine Temperature
While warm oil drains more easily, extremely hot oil can cause severe burns. It’s best to run your engine for a few minutes (5-10 minutes) to bring the oil to a warm, but not scalding, temperature. This allows contaminants to suspend in the oil, ensuring a more complete drain, while keeping it safe enough to handle.
Gather Your Gear: Tools and Supplies for the Job
Having all your tools and supplies ready before you start is one of the best how to drain engine oil tips you can get. A well-prepared workspace makes the process smoother, faster, and less frustrating. This section outlines everything you’ll need for a successful oil change.
Basic Tool Kit Essentials
You’ll need a socket wrench or box-end wrench that fits your vehicle’s drain plug. The size varies, but common sizes include 13mm, 15mm, 17mm, or 1/2-inch. A funnel is indispensable for refilling new oil without spills, and a torque wrench is highly recommended for properly tightening the drain plug to prevent leaks or damage.
Oil Collection and Disposal
A large oil drain pan is critical for collecting the old oil. Ensure it has sufficient capacity for your engine’s oil volume, usually 5-8 quarts for most passenger vehicles. For environmentally friendly disposal, have an empty container (like an old oil jug) ready to transfer the used oil to take to a recycling center. Don’t forget shop rags or old newspapers for cleanup.
New Oil and Filter
Always consult your vehicle’s owner’s manual for the correct type and viscosity of engine oil (e.g., 5W-30, 0W-20). Purchase the recommended amount, typically 4-7 quarts.

Step-by-Step: The Comprehensive Guide on How to Drain Engine Oil
This is the core of our how to drain engine oil guide, detailing each action you need to take. Following these steps carefully will ensure a clean, efficient, and successful oil change. We break down the process into manageable stages, making it easy to follow along.
Preparing Your Vehicle for the Drain
First, drive your vehicle for a few minutes to warm up the engine oil, as mentioned earlier. Park your vehicle on a flat, level surface and engage the parking brake. Use your jack to lift the front of the vehicle, then immediately place jack stands under the frame or designated lift points for stability. Once secure, lower the jack slightly so the vehicle rests firmly on the stands.
Locating and Removing the Drain Plug
Slide your oil drain pan under the engine, positioning it directly beneath the oil pan. The oil pan is typically a large, flat metal pan located at the bottom of the engine. The drain plug is a single bolt on the lowest part of this pan. Use your wrench to loosen the drain plug, turning it counter-clockwise. Be prepared for oil to start dripping once it’s loose.
Draining the Old Oil
Once the drain plug is loose enough, carefully remove it by hand, being mindful of the hot oil that will immediately begin to flow out. Position the drain pan to catch the initial rush, which can spray a bit. Allow the oil to drain completely, which usually takes 10-20 minutes. The stream will slow to a trickle, then to individual drips.
Replacing the Drain Plug
While the oil is draining, inspect the old drain plug and its washer (if applicable). It’s often recommended to replace the drain plug washer with a new one to ensure a leak-free seal. Once the oil has finished draining, clean the area around the drain plug opening. Reinstall the drain plug, tightening it by hand first, then with your wrench to the manufacturer’s specified torque using a torque wrench. Do not overtighten, as this can strip the threads.
Replacing the Oil Filter (Optional but Crucial)
While technically separate from draining the oil, replacing the oil filter is an integral part of a complete oil change. Locate the old oil filter, which is usually a canister-shaped component attached to the engine block. Place a small drain pan underneath it, as some oil will spill out. Use an oil filter wrench to loosen the old filter, then carefully spin it off by hand. Before installing the new filter, apply a thin film of fresh oil to the rubber gasket of the new filter. Screw the new filter on by hand until it’s snug, then give it an additional 1/4 to 1/2 turn with the wrench, following filter manufacturer instructions.
Refilling with Fresh Oil
With the drain plug and new oil filter securely in place, you can now add the fresh oil. Open the hood and locate the oil filler cap, usually marked “Oil” or with an oil can symbol. Remove the cap and place your funnel into the opening. Carefully pour the recommended amount and type of new engine oil into the engine. Pour slowly to avoid air bubbles and spills. After pouring, replace the oil filler cap securely.
Final Checks and Cleanup
Lower your vehicle off the jack stands. Start the engine and let it run for a minute or two, then shut it off. This allows the new oil to circulate and fill the filter. Wait a few more minutes for the oil to settle, then check the oil level using the dipstick. Add more oil if necessary to reach the “full” mark. Inspect the drain plug and oil filter for any leaks. Finally, clean up any spilled oil and prepare the old oil for recycling, demonstrating good eco-friendly how to drain engine oil practices.
Vehicle-Specific Considerations: Cars, Trucks, Off-Roaders, and Motorcycles
While the general principles of how to drain engine oil remain consistent, different vehicle types present unique challenges and considerations. Understanding these nuances ensures a smoother process, regardless of what you drive.
Standard Passenger Vehicles
Most sedans and compact cars are relatively straightforward. Their oil pans are often easily accessible. The main challenge might be limited ground clearance, making ramps or a low-profile jack and jack stands essential. Always ensure your vehicle is stable before crawling underneath.
Trucks and SUVs (Ground Clearance)
Trucks and SUVs typically offer better ground clearance, which can make accessing the drain plug easier without extensive lifting. However, their oil pans often hold more oil, so ensure your drain pan has adequate capacity. Some trucks may also have larger or more robust skid plates that need to be removed before accessing the oil pan.
Off-Road Vehicles (Skid Plates, Mud)
Off-roaders often have robust skid plates protecting vital components, including the oil pan. You’ll likely need to remove these before you can access the drain plug. Be prepared for mud, dirt, and debris that might be caked onto the underside of the vehicle. A thorough cleaning of the area around the drain plug is important before removal to prevent contaminants from entering the engine.
