How to Change Oil in Car: Step-by-Step Guide for Beginners

Changing the oil in your car is one of the essential maintenance tasks that can keep your engine running smoothly. It’s a task you can perform yourself, saving money and providing you with a sense of satisfaction. This article will walk you through the steps on how to change oil in a car, including what tools you need, the process, and tips to make it easy and efficient.

Why is Changing Your Oil Important?

Oil is the lifeblood of your car’s engine. It lubricates the engine components, reduces friction, and helps dissipate heat. Over time, oil becomes contaminated with dirt, metal particles, and other debris, making it less effective. Changing your oil regularly keeps your engine clean and prolongs its lifespan.

Regular oil changes:

• Help your engine run smoothly
• Increase fuel efficiency
• Prevent engine wear and damage
• Enhance overall vehicle performance

When to Change Your Oil

The frequency of oil changes depends on the type of vehicle you have, the type of oil used, and your driving habits. Generally, it’s recommended to change the oil every 3,000 to 5,000 miles, but some modern vehicles can go 7,500 miles or even more. Consult your owner’s manual for the recommended oil change interval for your specific car.

Signs You Need an Oil Change:
• Oil change light is on
• Engine sounds noisier than usual
• Oil is dirty or dark in color
• You smell burning oil

Tools and Materials Needed for an Oil Change

Before you start the oil change, gather the following tools and materials:

• Wrench (usually a 3/8-inch ratchet wrench)
• Oil filter wrench (for removing the oil filter)
• Drain pan (for catching the used oil)
• Funnel (to pour new oil into the engine)
• New oil (check the owner's manual for recommended type and quantity)
• New oil filter (compatible with your vehicle model)
• Car jack and jack stands (if needed, for raising the car)
• Gloves (to protect your hands from hot oil)
• Rags or paper towels (for cleaning up any spills)

Step-by-Step Guide on How to Change Oil in a Car

Now that you have the tools and materials ready, let’s go through the steps to change the oil in your car. Make sure your car is parked on a flat surface, and let the engine cool for a few minutes if it has been running.

Step 1: Prepare Your Vehicle

1. Park the car on a flat surface – Avoid sloped surfaces as this can cause oil spillage.

2. Turn off the engine and let it cool for 5-10 minutes.

3. Engage the parking brake for extra safety.

4. If your vehicle is low to the ground, jack up the car and secure it with jack stands.

Step 2: Locate the Oil Drain Plug

1. Put on your gloves and crawl under the car (use a creeper if you have one).

2. Locate the oil drain plug. It’s typically on the bottom of the engine oil pan. Your car’s owner’s manual should have a diagram.

3. Place the drain pan directly under the drain plug to catch the used oil.

Step 3: Drain the Old Oil

1. Use the wrench to loosen the oil drain plug. Be careful, as the oil can be hot.

2. Once the plug is loose, carefully remove it by hand and let the oil drain into the pan.

3. Allow the oil to drain completely, which usually takes a few minutes.

4. Once all the oil is drained, clean the drain plug with a rag and replace it by hand, then tighten it with a wrench.

Step 4: Remove the Old Oil Filter

1. Locate the oil filter (consult your owner’s manual if needed). It’s usually on the side of the engine.

2. Position the drain pan under the filter, as some oil may leak out when you remove it.

3. Use the oil filter wrench to loosen and remove the old oil filter.

4. Be cautious as it will still contain some oil, which can spill when you remove it.

Step 5: Install the New Oil Filter

1. Take the new oil filter and apply a small amount of fresh oil on the rubber gasket at the top of the filter. This helps ensure a good seal.

2. Screw the new filter onto the engine by hand until it’s snug. Then give it another quarter turn to tighten. Do not overtighten the oil filter.

Step 6: Add New Oil

1. Open the oil filler cap located on top of the engine.

2. Use a funnel to pour the recommended amount of new oil into the engine.

3. After adding the oil, replace the oil filler cap and make sure it’s secure.

Step 7: Check the Oil Level

1. Start the engine and let it run for a minute or two, allowing the new oil to circulate.

2. Turn off the engine and wait a minute, then check the oil level with the dipstick.

3. Pull out the dipstick, wipe it clean, insert it back fully, then pull it out again to check the level. If it’s below the “Full” mark, add a bit more oil and recheck.

Step 8: Dispose of Used Oil Properly

Used motor oil is toxic to the environment, so it must be disposed of responsibly. Most auto parts stores and service stations accept used oil for recycling. Pour the old oil into a sealed container and take it to a recycling facility.

Tips for an Easy Oil Change

• Warm up the engine slightly before changing the oil. Warm oil flows out more quickly.

• Always double-check that you’ve replaced the drain plug and oil filter before adding new oil.

• Take your time – rushing can lead to mistakes and messes.

• Keep a record of the oil change with the date and mileage. This helps you stay on track with future oil changes.

• Make sure you’re using the right type of oil for your car. Check the owner’s manual for the manufacturer’s recommendation.

Common Mistakes to Avoid When Changing Oil in a Car

1. Overfilling or Underfilling the Oil

Adding too much oil can increase the pressure inside the engine and cause leaks, while too little oil won’t provide enough lubrication. Always use the dipstick to check the level after filling.

2. Using the Wrong Type of Oil

Oil type and viscosity are critical for engine performance. Consult your owner’s manual to ensure you’re using the correct type.

3. Not Replacing the Oil Filter

An old oil filter can introduce contaminants into the new oil, reducing its effectiveness. Always replace the oil filter when you change the oil.

4. Not Tightening the Drain Plug or Filter

If the drain plug or filter is too loose, you could end up with an oil leak. However, overtightening can strip the threads or damage the rubber seal on the oil filter.

How Much Does an Oil Change Cost?

The cost of an oil change varies depending on whether you do it yourself or go to a shop. Changing the oil yourself can cost between $20 and $50, depending on the type of oil and filter you buy. Going to a shop or dealership can cost between $35 and $75 or more, depending on the type of vehicle and location.

How Long Does an Oil Change Take?

For beginners, changing the oil may take around 30 to 45 minutes. As you become more experienced, you can complete the process in as little as 20 minutes. Remember, taking your time and being thorough is better than rushing through the steps.

Benefits of Changing Your Own Oil

Changing your own oil offers several benefits:

• Saves Money: Doing it yourself can save you labor costs associated with a professional oil change.

• Increases Knowledge: Performing maintenance helps you learn more about how your vehicle operates.

• Provides Satisfaction: There’s a sense of accomplishment in knowing you did it yourself.
