How to Change Engine Oil — A Beginner’s Guide

The exact oil specification, capacity, drain-plug torque, filter type, and service interval vary by vehicle. Before starting, verify every vehicle-specific detail in the owner’s manual or the manufacturer’s service information.

Before You Start

Work on a stable, level surface and allow the engine to cool enough to work safely. Confirm the correct oil specification and quantity, the correct replacement filter, and that all of your tools are ready before you begin.

Tools & Materials

Exact requirements depend on the vehicle, but a typical oil change may need:

• Correct engine oil
• Replacement oil filter
• Oil drain pan
• Socket, ratchet, or correct drain-plug tool
• Oil-filter wrench, if required
• Funnel
• Gloves and shop towels or rags
• Jack and properly rated jack stands, if required
• Wheel chocks where appropriate

Step 1 — Prepare the Vehicle

Park safely, engage the parking brake, and follow the manufacturer’s lifting points if the vehicle needs to be raised. Secure it properly before going underneath. Open the hood and locate the oil filler cap, drain plug, and oil filter.

Step 2 — Drain the Old Engine Oil

Position the drain pan so it catches the oil, remembering that the flow direction can change as draining slows. Carefully loosen the drain plug and allow the oil to drain fully. Inspect the plug and sealing washer or gasket, replacing the washer or gasket when the manufacturer specifies it.

Step 3 — Replace the Oil Filter

Place the drain pan underneath the filter because residual oil may spill. Remove the old filter and check that its gasket did not remain attached to the engine. Where applicable, lightly lubricate the new filter gasket with clean engine oil, then install the filter according to its instructions. Do not invent a tightening specification; follow the filter or vehicle manufacturer’s guidance.

Step 4 — Reinstall the Drain Plug

Clean the area around the drain opening. Install the correct washer or seal if required, reinstall the drain plug, and tighten it to the manufacturer’s specification. Do not guess the torque value.

Step 5 — Add Fresh Engine Oil

Verify that the drain plug and filter are installed. If the vehicle was lifted, lower it safely before the final level check. Add the manufacturer-specified oil gradually through a funnel, taking care not to overfill. Reinstall the oil filler cap.

Step 6 — Start the Engine and Check

Start the engine and verify that the oil-pressure warning indicator behaves normally. Let the engine run briefly, then switch it off. Inspect the drain plug and filter area for leaks. Wait the period recommended by the manufacturer before checking the level. Use the dipstick if the vehicle has one; some modern vehicles use an electronic oil-level measurement instead. Add only small amounts if necessary.

Step 7 — Clean Up and Dispose of Used Oil

Transfer the used oil into a sealed, suitable container. Never pour it onto the ground, into drains, or into household waste. Take it to an appropriate used-oil collection or recycling facility according to local regulations, and recycle or dispose of the used filter appropriately.

Common Beginner Mistakes

• Using the wrong oil specification
• Overfilling
• Forgetting a drain-plug washer
• Double-gasketing the oil filter
• Overtightening the filter
• Guessing drain-plug torque
• Forgetting to reinstall the oil filler cap
• Failing to check for leaks
• Working underneath an improperly supported vehicle

Quick Checklist Before You’re Done

• Drain plug installed correctly
• Oil filter installed correctly
• Correct amount and specification of oil added
• Oil filler cap installed
• Oil level checked
• No visible leaks
• Tools removed from the engine bay
• Used oil stored for proper recycling
