Car oil change
Changing your car’s oil is one of the most essential maintenance tasks for keeping your engine running smoothly — and it’s surprisingly easy to do yourself. Whether you’re a first-time DIYer or trying to save money on auto shop bills, this step-by-step guide will walk you through how to do an oil change at home safely and efficiently in 2025.
Why Oil Changes Matter
Motor oil lubricates the engine’s internal parts, reduces friction, and helps prevent overheating. Over time, oil breaks down and collects debris, which can damage your engine if not replaced regularly. That’s why experts recommend changing your oil every 3,000 to 7,500 miles, depending on your vehicle and driving habits.
What You’ll Need
- New oil (check your car’s manual for type and quantity)
- New oil filter
- Oil filter wrench
- Socket wrench or spanner
- Drain pan
- Funnel
- Car jack and jack stands or ramps
- Gloves and safety goggles
- Old rags or paper towels
Step-by-Step Guide to Changing Your Oil
Step 1: Prepare Your Workspace
Park your car on a flat surface and let the engine cool down for at least 30 minutes to avoid burns. Gather all tools and materials before you begin. Make sure the parking brake is engaged.
Step 2: Jack Up the Car
Use a car jack to lift the vehicle and place jack stands underneath for safety. Alternatively, you can use car ramps. Never rely on the jack alone — always secure your car properly.
Step 3: Locate the Drain Plug
Slide under the vehicle and locate the oil drain plug on the oil pan (usually at the bottom of the engine). Place the drain pan directly underneath the plug.
Step 4: Drain the Old Oil
Use a socket wrench to slowly loosen the drain plug. Be cautious — the oil might still be warm. Allow all the old oil to drain completely into the pan. This may take 5–10 minutes.
Step 5: Remove the Old Oil Filter
Use an oil filter wrench to remove the old filter. Be careful — some oil may spill out. Check that the rubber gasket came off with the filter. If not, remove it from the engine manually.
Step 6: Install the New Oil Filter
Apply a small amount of new oil to the gasket of the new filter for a better seal. Screw it into place by hand until snug. Do not over-tighten.
Step 7: Replace the Drain Plug
Once the old oil has fully drained, reinstall the drain plug and tighten it securely with a wrench — but don’t overtighten to avoid stripping the threads.
Step 8: Add New Oil
Open the hood and locate the oil filler cap. Place a funnel inside and pour in the new oil as per the manufacturer’s recommended quantity. Use a dipstick to check the level — it should be between the minimum and maximum lines.
Step 9: Run the Engine Briefly
Start your car and let it run for 1–2 minutes. This allows the new oil to circulate. Turn off the engine and wait a few minutes before rechecking the oil level and topping off if needed.
Step 10: Clean Up and Dispose of Old Oil
Properly dispose of the used oil and filter at a local recycling center or auto parts store that accepts used oil. Never pour oil down the drain or into the ground — it’s toxic to the environment.
Tips for a Smooth Oil Change
- Wear gloves to keep your hands clean and protected.
- Label the oil container to avoid confusing it with new oil.
- Keep records of oil changes to track maintenance history.
- Double-check filter and plug tightness to avoid leaks.
When to Change Your Oil
Besides mileage, look out for these signs:
- Dark, dirty oil on the dipstick
- Check engine or oil warning light is on
- Engine running rougher than usual
- Excessive exhaust smoke
