Regular oil changes are among the most critical maintenance tasks for preserving your engine’s longevity and performance. Learning how to change oil in car is a straightforward process that can save you money and give you confidence in your vehicle’s upkeep. This guide will walk you through every step, from gathering tools to disposing of the old oil safely.
You do not need to be a mechanic to complete this job. With some basic tools, a little time, and careful attention, you can perform this essential service in your own driveway or garage. Let’s get started.
How To Change Oil In Car
This section provides the complete, step-by-step procedure. Before you begin, ensure you have all the necessary items and that your car is parked on a level surface with the engine off and cool. Safety is the first priority.
Tools And Materials You Will Need
Gathering everything before you start is crucial. There’s nothing worse than being under the car and realizing you’re missing a key tool. Here is your checklist.
- New Engine Oil: Check your owner’s manual for the correct type (viscosity like 5W-30) and quantity.
- New Oil Filter: Ensure it matches your car’s make, model, and engine size.
- Wrench or Socket Set: For removing the drain plug. A ratchet and the correct size socket is best.
- Oil Filter Wrench: This special tool grips the filter for easy removal. Types include cap-style, strap, or claw.
- Drain Pan: A dedicated pan to catch the old oil. Get one with a capacity greater than your engine’s oil volume.
- Funnel: For pouring new oil cleanly into the engine.
- Jack and Jack Stands or Car Ramps: To safely elevate the vehicle. Never rely on a jack alone.
- Gloves and Safety Glasses: Protect your hands and eyes from hot oil and dirt.
- Rags or Paper Towels: For cleaning up spills and drips.
Step By Step Oil Change Procedure
Follow these steps in order for a smooth and mess-free oil change. Take your time, especially if this is your first attempt.
Step 1: Prepare Your Vehicle
Park your car on a flat, solid surface like a driveway. Engage the parking brake firmly. If you have an automatic transmission, place it in “Park.” For a manual, put it in gear. For extra safety, place wheel chocks behind the rear tires.
Step 2: Warm Up The Engine Briefly
Run the engine for about 5 minutes. Warm oil flows out more quickly and completely, carrying more contaminants with it. Do not get the engine piping hot, as this can be dangerous.
Step 3: Safely Lift The Car
This is the most critical safety step. Use a floor jack to lift the front of the car according to the manufacturer’s designated lift points, usually behind the front wheels. Then, immediately place jack stands under the reinforced frame or lift points. Lower the jack onto the stands. Give the car a gentle shake to ensure it is stable. If using ramps, drive up them carefully and apply the parking brake.
Step 4: Locate The Drain Plug And Oil Filter
Slide your drain pan under the engine oil pan. The drain plug is a large bolt on the bottom of the oil pan. The oil filter is usually nearby—a cylindrical canister either on the side or bottom of the engine.
Step 5: Drain The Old Oil
Put on your gloves and safety glasses. Using your wrench, loosen the drain plug slowly. Finish unscrewing it by hand, but be prepared for hot oil to gush out. Push the plug away quickly as the last threads release, letting the oil flow into the pan. Allow it to drain completely for at least 10-15 minutes.
Step 6: Remove The Old Oil Filter
Position the drain pan under the filter. Use your oil filter wrench to loosen it. Oil will drip out, so be ready. Once loose, unscrew it by hand. Tip it upside down to minimize drips. Wipe clean the filter mounting surface on the engine with a rag.
Step 7: Install The New Oil Filter And Plug
Take your new filter and dip your finger in some fresh oil. Smear a thin layer of oil on the rubber gasket of the new filter. This creates a better seal. Screw the new filter on by hand until the gasket makes contact, then tighten it an additional three-quarter turn by hand. Do not use the wrench for this final tighten unless absolutely necessary. Clean the drain plug and its washer, replace the washer if needed, and screw the plug back in by hand. Tighten it snugly with the wrench, but avoid over-tightening, which can strip the threads.
Step 8: Lower The Car And Add New Oil
Carefully lift the car slightly to remove the jack stands, then lower it completely to the ground. Remove the oil filler cap on top of the engine. Place your funnel in the opening and begin pouring the new oil. Refer to your manual for the correct amount; usually it’s 4 to 6 quarts. Pour in about three-quarters of the amount first, then wait a minute for it to settle.
Step 9: Check The Oil Level
After adding most of the oil, insert the dipstick, pull it out, and check the level. Add more oil in small increments, checking the dipstick each time, until the level reaches the “Full” mark. Do not overfill.
Step 10: Run The Engine And Check For Leaks
Replace the oil filler cap. Start the engine and let it run for about 30 seconds. The oil pressure light should go off after a few seconds. Look under the car for any drips from the drain plug or filter. Turn off the engine, wait two minutes, and check the dipstick one final time, adding a bit more oil if needed.
Disposing Of The Old Oil And Filter
Never pour used oil down a drain, on the ground, or into the trash. It is highly toxic and contaminates the environment. Pour the oil from your drain pan into the empty new oil containers. Take the used oil and the old filter to a recycling center. Most auto parts stores and service stations accept used oil for free. They often take the old filter too.
Choosing The Right Oil And Filter
Using the correct products is as important as the change itself. Your vehicle’s owner’s manual is the final authority. It specifies the recommended oil viscosity (like 0W-20, 5W-30) and performance standard (like API SN).
For oil filters, don’t just buy the cheapest option. A quality filter has better anti-drain back valves and filtration media, which protects your engine between changes. Stick with reputable brands you recognize.
Common Mistakes To Avoid
Being aware of these pitfalls will help ensure your oil change is successful and safe.
- Over-tightening the Drain Plug or Filter: This can strip threads or crush gaskets, leading to leaks. Snug is sufficient.
- Using the Wrong Oil: Consult your manual. Using the incorrect viscosity can affect engine performance and fuel economy.
- Forgetting to Lubricate the New Filter Gasket: A dry gasket can tear or not seal properly, causing a leak.
- Not Checking for Leaks Afterward: Always do a final check with the engine running to catch any issues early.
- Improperly Disposing of Oil: It’s illegal and harmful. Always recycle it properly.
How Often Should You Change Your Oil?
The old rule of every 3,000 miles is largely outdated for modern cars and oils. Many manufacturers now recommend intervals of 5,000, 7,500, or even 10,000 miles. Your driving conditions matter greatly. “Severe service” driving—such as frequent short trips, extreme temperatures, stop-and-go traffic, or towing—requires more frequent changes. Always default to the schedule in your owner’s manual, adjusting for your specific driving habits.
FAQ Section
How Long Does It Take To Change Oil In A Car?
For a beginner, the entire process, including setup and cleanup, typically takes about 45 to 60 minutes. With experience, you can complete it in 30 minutes.
Can I Change My Oil Without Jacking Up The Car?
On some vehicles with high ground clearance, like trucks or SUVs, you might be able to reach the drain plug without lifting it. However, for most sedans and compact cars, you will need to safely elevate the front end to gain proper access and working room.
What Is The Difference Between Synthetic And Conventional Oil?
Conventional oil is refined from crude oil. Synthetic oil is chemically engineered to provide superior performance in extreme temperatures, better engine cleanliness, and longer-lasting protection. Many modern cars require synthetic or a synthetic blend.
What Happens If I Put Too Much Oil In My Car?
Overfilling can cause serious damage. Excess oil can be whipped into foam by the crankshaft, leading to poor lubrication, increased pressure, and potential seal failures. If you overfill, you must drain the excess to the proper level.
Is Changing Your Own Oil Worth It?
Financially, yes. You save on labor costs and can often buy supplies on sale. Beyond money, you gain the satisfaction of completing basic maintenance and the assurance that the job was done correctly with quality parts. It’s a valuable skill for any car owner to have.
