Drain the Old Oil Effectively

Locate and Remove the Drain Plug

Find the oil pan underneath your vehicle—it’s usually at the bottom center of the engine block. Using your socket wrench, carefully loosen and remove the drain plug. Prepare your drain pan to catch the oil. When I first did this, I used a small bowl, and oil splashed everywhere. Switching to a larger drain pan made the process cleaner. Keep a rag handy to wipe residual oil from the drain plug and surrounding area.

Promote Complete Oil Flow

Let the old oil fully drain out—this might take 10-15 minutes. To speed this up, slightly tilt the drain pan to ensure all residual oil flows out. During my first attempt, I rushed and didn’t wait long enough, leaving behind sludge. Patience here ensures your engine gets rid of contaminated oil, reducing sludge buildup down the line.

Replace the Oil Filter Properly

Locate the oil filter—often accessible from the top or bottom of the engine. Use an oil filter wrench to unscrew it carefully. Before installing the new filter, lightly coat its rubber gasket with fresh oil to ensure a proper seal, preventing leaks. I once forgot this step, and it resulted in oil seeping after a week. Tighten the new filter securely, but avoid over-tightening which can damage the gasket.

Refill with Fresh Oil

Insert a funnel into the oil fill port and pour in the recommended amount and type of fresh oil. Refer to your vehicle’s manual or engine specifications for guidance. After filling, replace the oil cap tightly. I recommend checking the dipstick after a few minutes, wiping it clean, then re-inserting to check oil level accuracy. Overfilling can cause foaming and reduce lubrication efficiency, so aim precisely.
