How to Change Oil: A Complete Step-by-Step Guide for Beginners (2025)

Changing your engine oil is one of the most important car maintenance tasks you can do yourself. If you’re wondering how to change oil, how often it should be done, or whether it’s worth doing at home, this detailed guide will answer all your questions.

Regular oil changes improve engine performance, increase fuel efficiency, and extend the life of your vehicle. Whether you drive a sedan, SUV, or pickup truck in the US, learning how to change oil in a car can save you money and help you understand your vehicle better.

Why Oil Changes Are So Important

Engine oil lubricates moving parts, reduces friction, and helps keep the engine cool. Over time, oil becomes dirty and loses its effectiveness. When this happens, your engine works harder and can suffer permanent damage.

Benefits of Regular Oil Changes

Improves engine performance
Prevents overheating
Reduces engine wear
Improves gas mileage
Extends engine lifespan

Skipping oil changes can lead to sludge buildup, reduced efficiency, and expensive repairs.

How Often to Change Oil (Updated US Guidelines)

One of the most common questions drivers ask is how often to change oil.

General Oil Change Intervals

Conventional oil: Every 3,000–5,000 miles
Synthetic blend: Every 5,000–7,500 miles
Full synthetic oil: Every 7,500–10,000 miles

However, always check your vehicle owner’s manual. Modern cars in the US often recommend longer intervals, especially if you use synthetic oil.

Factors That Affect Oil Change Frequency

Driving in extreme heat or cold
Frequent short trips
Towing or heavy loads
Stop-and-go traffic

If you drive under severe conditions, you may need oil changes more often.

How to Change Oil: Step-by-Step Instructions

Follow these steps carefully to safely and correctly perform an oil change.

Step 1: Warm Up the Engine

Start your car and let it run for 2–3 minutes. Warm oil drains faster and removes more contaminants.

Step 2: Lift the Vehicle Safely

Park on level ground, engage the parking brake, and lift the vehicle using ramps or a jack and jack stands.

⚠️ Safety first: Never work under a car supported only by a jack.

Step 3: Drain the Old Oil

Place the drain pan underneath
Use a wrench to loosen the plug
Let the oil drain completely (5–10 minutes)

Replace the drain plug securely once finished.

Step 4: Remove and Replace the Oil Filter

Use an oil filter wrench to remove the old filter
Lightly oil the rubber gasket on the new filter
Install the new filter hand-tight (do not over-tighten)

This step is essential when learning how to change oil in car correctly.

Remove the oil fill cap
Insert a funnel
Pour in the recommended amount of new oil
Replace the cap securely

Step 6: Check Oil Level

Turn off the engine
Check the oil level using the dipstick
Add more oil if needed
