How to Change Engine Oil & Filter Step by Step (Complete Guide)

TL;DR

Changing your engine oil and filter is one of the most important maintenance tasks for keeping your car reliable. This guide explains the step-by-step process, safety precautions, and why choosing genuine parts from Automan Spare Parts ensures long-lasting performance, warranty coverage, and worldwide fast shipping.

Why Engine Oil Change Is Important

Engine oil is the lifeblood of your vehicle. It lubricates moving parts, reduces friction, and keeps the engine cool. Over time, however, oil degrades and loses its protective qualities. Delaying an oil change can lead to:

• Increased engine wear

• Overheating issues

• Reduced fuel efficiency

• Potential engine failure

Changing your engine oil and filter regularly not only protects your engine but also extends your vehicle’s life. At Automan Spare Parts, we provide OEM-tested parts including oil filters, ECU units, fuse boxes, and transmission components — all with a 30-day replacement warranty and worldwide fast shipping to the USA, UK, Saudi Arabia, Germany, Singapore, Australia, France, Canada, Nigeria, and more.

Tools & Supplies You’ll Need

Before you begin, prepare the following:

• Correct grade and quantity of engine oil (refer to your owner’s manual)

• New OEM-approved oil filter

• Oil filter wrench

• Socket wrench set

• Oil drain pan

• Funnel

• Jack and jack stands (or ramps)

• Gloves and protective glasses

• Rags or paper towels

Tip: Always use an OEM-approved filter for proper compatibility and warranty compliance.

Safety Precautions Before Changing Engine Oil

Taking precautions is essential for a safe and effective oil change:

• Work on a flat, stable surface.

• Ensure the engine is slightly warm, not hot, to avoid burns.

• Wear gloves and safety glasses to prevent contact with hot oil or chemicals.

• Use jack stands or ramps — never rely solely on a hydraulic jack.

• Keep rags handy for spills and wipe any oil from surfaces.

• Dispose of old oil at a certified recycling facility.

Step-by-Step Guide: How to Change Engine Oil & Filter

Step 1: Warm Up the Engine

Run the engine for 3–5 minutes. Warm oil drains faster and carries away debris.

Step 2: Secure the Vehicle

• Park on a level surface.

• Engage the parking brake.

• Safely raise the car with a jack and support it on jack stands.

Step 3: Drain the Old Oil

1. Place the drain pan beneath the oil sump.

2. Remove the drain plug with a socket wrench.

3. Allow the oil to drain completely (about 10–15 minutes).

Step 4: Replace the Oil Filter

• Use an oil filter wrench to remove the old filter.

• Apply a thin layer of fresh oil to the new filter gasket.

• Hand-tighten the new filter until secure.

Step 5: Reinstall the Drain Plug

• Clean the drain plug and sump area.

• Refit the plug securely, avoiding over-tightening.

Step 6: Add New Oil

1. Place a funnel in the filler neck.

2. Pour the recommended grade and amount of oil.

3. Secure the oil filler cap.

Step 7: Check Oil Level

• Start the engine and let it run briefly.

• Turn off the engine and wait 5 minutes.

• Check the dipstick and top up if necessary.

Step 8: Dispose of Used Oil Responsibly

Always recycle oil at an authorized facility. Improper disposal can harm the environment.
