How to Change the Oil in Your Car

Short answer

Changing the oil in your car means draining the old, dirty oil, replacing the oil filter, and refilling with fresh oil to keep your engine lubricated and running well. By following clear, step-by-step instructions and using the right tools, anyone can successfully do an oil change at home, saving money and extending the life of their vehicle.

What Do You Need Before Starting an Oil Change?

To prepare for an oil change, collect all necessary supplies to avoid interruptions and keep the work area safe and clean. Here’s a detailed list of what you’ll need:

Setting up a clean, level workspace in a garage or driveway with enough light will also help. Lay down old newspapers or cardboard under the car to catch drips. Having everything ready before starting saves time and reduces frustration.

What Is an Oil Change and Why Is It Important?

An oil change involves removing the old engine oil and oil filter and replacing them with fresh oil and a new filter. Engine oil lubricates the metal parts inside your engine, minimizing friction and heat buildup. Over time, oil degrades and collects dirt, metal particles, and other contaminants, reducing its effectiveness.

If the oil isn’t changed regularly, the engine runs with dirty, thickened oil that can cause increased wear, overheating, and possible engine failure. New oil ensures smooth engine operation, better fuel efficiency, and fewer emissions.

For example, imagine if you never changed the oil in your car and kept driving—it’s like running a machine without grease; parts grind and wear out faster. Changing the oil regularly—usually every 3,000 to 7,500 miles depending on your vehicle and oil type—helps avoid costly repairs down the road.

Some newer cars with synthetic oil or special filters can go longer between changes, but always refer to your owner’s manual for specific recommendations. Regular oil changes are one of the simplest, most effective ways to maintain your car.

How Do You Change the Oil in Your Car? Step-by-Step Instructions

Here is a detailed step-by-step process with explanations for why each step is important:

  1. Prepare your vehicle and workspace Park your car on a flat, stable surface. Turn off the engine and let it cool for at least 15-30 minutes because hot oil can cause burns. Engage the parking brake and use wheel chocks behind the rear wheels for extra safety.
  1. Lift the car Use a car jack to raise the front end if needed, then securely place jack stands under the vehicle’s frame. Alternatively, drive the car onto ramps rated for your vehicle’s weight. Never crawl under a car supported only by a jack.
  1. Locate the oil drain plug and oil filter Consult your owner’s manual if you’re unsure. Typically, the drain plug is a bolt at the bottom of the oil pan on the underside of the engine. The oil filter is usually nearby and looks like a small canister.
  1. Drain the old oil Place the oil drain pan under the drain plug. Using the correct wrench, loosen and remove the plug carefully—oil will start flowing out, so keep your face and hands clear. Let the oil drain completely (about 5-10 minutes). This removes old, dirty oil from the engine.
  1. Remove the old oil filter Use an oil filter wrench to unscrew it counterclockwise. Be prepared for some oil to spill out. Keep the drain pan underneath to catch this. Removing the old filter clears out trapped contaminants.
  1. Prepare and install the new oil filter Apply a thin layer of fresh oil to the rubber gasket on the new filter—this helps create a tight seal and makes it easier to remove next time. Screw the filter on by hand until it’s snug, then tighten it an additional ¾ turn. Avoid over-tightening as this can damage the filter or seal.
  1. Replace the drain plug Once oil has fully drained, clean the drain plug and the area around the oil pan. Reinstall the drain plug and tighten it firmly with the wrench, but do not overtighten to avoid stripping the threads.
  1. Add new oil Open the hood and remove the oil filler cap on top of the engine. Using a funnel, pour in the quantity and type of oil specified in your manual. For example, if your car takes 5 quarts, pour slowly and pause to allow oil to settle.
  1. Check the oil level Wait a few minutes, then pull out the dipstick, wipe it clean, insert it fully, and pull it out again to check the oil level. Add more oil as needed to reach the “full” mark, but don’t overfill.
  1. Start the engine and check for leaks Start your car and let it run for a few minutes. Watch under the car for any oil leaks around the drain plug or filter. Check the oil pressure or warning lights on your dashboard; they should turn off.
  1. Dispose of used oil properly Pour the used oil from the drain pan into a sealed container (like the empty oil bottles). Take this to an auto parts store, recycling center, or hazardous waste facility that accepts used motor oil. Never pour it down drains or onto soil.

How Can You Tell If the Oil Change Worked?

After completing the oil change, several signs will indicate success:

If the oil level drops quickly or you see leaks, double-check that the drain plug and oil filter are tight and properly installed. Any persistent issues should be inspected by a mechanic.

What Should You Do If Something Goes Wrong?

Problems can happen during an oil change. Here’s what to do if you encounter issues:

If you feel unsure or the car behaves abnormally after the oil change, have a professional mechanic inspect the vehicle. Driving with incorrect oil levels or leaks risks costly repairs.

How Should You Adapt Oil Changes for Different Drivers?

Changing oil can be adjusted based on experience, age, or physical ability:

Adapting the process helps everyone feel capable of maintaining their car and builds valuable life skills.

Why Should You Change the Oil in Your Car Regularly?

Regular oil changes are a key part of car maintenance because:

Skipping or delaying oil changes can cause diminished engine performance, increased fuel consumption, and eventual engine failure. For example, driving 10,000 miles without an oil change can risk sludge forming inside the engine, leading to costly repairs.

Your owner’s manual will specify oil change intervals based on your car’s design and the type of oil used. Following these guidelines helps save money long term and keeps your vehicle reliable.

Frequently asked questions

How do I know which oil to buy for my car?

Check your vehicle's owner’s manual for the recommended oil type and viscosity (like 5W-30). Many manuals also list suitable brands. If unsure, an auto parts store can help you choose the correct oil based on your car’s make and model.

Can I change my own oil if I have never done it before?

Yes, with the right tools, patience, and safety precautions, beginners can change their car’s oil. Following a step-by-step guide and watching tutorial videos can make the process easier. If you feel uncomfortable at any point, seek help from a professional.

How should I dispose of old motor oil responsibly?

Used motor oil should be collected in a sealed container and taken to an approved recycling center, auto parts store, or hazardous waste facility. Never pour it down drains, on the ground, or in trash bins, as it contaminates water and soil.

What if I drop the drain plug or oil filter bolt in the engine bay?

Do not try to start the car. Retrieve the dropped part carefully if possible. If it’s lost inside the engine, call a mechanic. Driving without a drain plug will cause oil to leak and severe engine damage.

How long does an oil change usually take?

For someone experienced, an oil change can take 30-45 minutes. Beginners might need up to an hour or more as they learn the steps and handle tools safely.
