Why Changing Your Oil In Your Car Is Important?

Changing the oil in your car is important for keeping the engine running smoothly. Fresh oil helps lubricate the engine’s moving parts, reducing friction and preventing unnecessary wear.

As oil ages, it becomes less effective and can pick up dirt and debris, which may damage the engine. Regular oil changes ensure that your engine stays clean and operates at peak performance, improving fuel efficiency.

Neglecting oil changes can lead to overheating and even complete engine failure. Keeping the oil fresh protects your car from costly repairs and extends its overall lifespan.

How To Prepare For An Oil Change?

Before starting, ensure you have the right tools and materials. Having everything at hand will make the oil change process easier and more efficient.

Engine Oil

Start by selecting the correct engine oil for your car. Refer to your car’s owner’s manual to find the recommended oil type and viscosity, such as 5W-30 or 10W-40, to ensure you’re using the right oil for optimal engine performance.

Oil Filter

Make sure to get a new oil filter before beginning the oil change. Replacing the oil filter each time is crucial for keeping the engine clean, as it traps contaminants and prevents them from circulating in the engine.

Oil Drain Pan

You will need an oil drain pan to collect the used oil when draining it from the engine. This will keep the process clean and ensure the old oil is disposed of safely and efficiently.

Wrench Set

A wrench set is necessary to remove the oil drain plug and the oil filter. Be sure to use the correct size to avoid damaging the bolts or the components of the engine.

Funnel

Use a funnel when adding new oil to the engine. The funnel allows you to pour the oil precisely into the oil filler cap without making a mess.

Jack and Jack Stands

If the oil pan is hard to reach, use a jack and jack stands to lift the car. Raising the car will give you the necessary clearance to access the oil drain plug and the oil filter with ease.

Rubber Gloves

Wearing rubber gloves is essential to protect your hands from oil and grime. Gloves keep you clean and prevent harmful chemicals from coming into contact with your skin.

Rags or Paper Towels

It’s a good idea to have rags or paper towels nearby to clean up any spills during the oil change. Having them on hand helps maintain a clean work area and ensures you don’t make unnecessary messes.

New Washer for the Drain Plug

If your car uses a crush washer on the oil drain plug, replace it with a new one. The fresh washer ensures a secure, leak-free fit when you reinstall the drain plug after draining the oil.

What Are The Safety Guidelines You To Follow?

Park on a Flat Surface

Make sure your car is parked on level ground before you start. This will prevent the car from shifting or rolling while you’re working, keeping everything stable and safe.

Use Jack Stands for Stability

If you need to lift the car, always use jack stands along with the jack. A jack alone isn’t enough to safely support the weight of the vehicle, so jack stands are essential.

Wear Protective Gear

Be sure to wear rubber gloves to protect your hands from oil and grime. Oil can irritate your skin, so gloves help keep you safe and clean during the process.

Cool Down the Engine

Let the engine cool down for 10 to 15 minutes before you begin. Working with hot oil can cause burns, so it’s important to give it time to cool off.

Check for Leaks After Installation

Once you’ve added the new oil and reinstalled the drain plug and filter, start the engine briefly. This will help you check for any leaks around the drain plug and oil filter to make sure everything is properly sealed.

Dispose of Used Oil Properly

Take your used oil to a recycling center or an auto parts store that accepts it. Never dispose of used oil down the drain or in the trash as it’s harmful to the environment.

Avoid Over-tightening

When reinstalling the drain plug and oil filter, tighten them by hand. Over-tightening can cause damage to the components and lead to leaks.

Clean Up Spills Immediately

Keep rags or paper towels nearby to clean up any spills right away. This helps keep your workspace clean and safe, and it makes the entire process easier.

Step-by-Step Process to Change Your Car Oil

Step 1: Get Your Car Ready

Start by ensuring that your car is parked on a flat and stable surface. This helps prevent any shifting or movement while you work, making the process much safer.

If your car has low clearance, use a jack to lift the car, then secure it with jack stands. These tools are essential for safely supporting the vehicle while you access the oil pan.

Before beginning the oil change, let the engine cool down for about 10 to 15 minutes. Hot oil can cause burns, so this waiting period is important for your safety.

Step 2: Drain the Old Oil

Position an oil drain pan underneath the oil pan to catch the used oil. Make sure the pan is large enough to hold the total amount of oil your engine holds.

Using the proper wrench, carefully remove the oil drain plug and allow the oil to drain out completely. It’s important to give it time, this process may take several minutes to ensure all the oil is drained.

As the oil drains, keep an eye on its condition. If you notice metal particles or unusual debris, it could signal internal engine damage and may require professional attention.

Step 3: Swap Out the Oil Filter

Once the oil has finished draining, use an oil filter wrench to remove the old oil filter. Be cautious, as some oil may still spill out of the filter during this process.

Before installing the new oil filter, wipe the area around the oil filter mount to remove any excess oil or debris. This ensures that the new filter fits snugly and seals properly.

Apply a thin layer of fresh oil to the rubber seal of the new filter before installing it. This step helps the filter seat properly and makes it easier to remove during the next oil change.

Step 4: Put the Drain Plug Back On

After the oil has drained, reinstall the oil drain plug and tighten it with a wrench. Be sure not to over-tighten the plug to avoid damaging the threads.

If your vehicle uses a crush washer, replace it with a new one. A fresh washer ensures a tight, leak-proof seal when you reinstall the drain plug.

Check that the drain plug is securely tightened. A loose or improperly sealed plug can lead to oil leaks, causing further issues down the road.

Step 5: Add the New Oil

Using a funnel, slowly pour the recommended amount of fresh oil into the engine. Always refer to your vehicle’s owner’s manual to ensure you’re using the correct type and amount of oil for your car.

After pouring in the new oil, use the dipstick to check the oil level. If necessary, add more oil in small increments to avoid overfilling.

Once the oil level is correct, start the engine briefly to allow the new oil to circulate. This helps to ensure that the oil is properly distributed throughout the engine.

Step 6: Double-Check and Clean Up

Start the engine and let it run for a minute or two to allow the oil to circulate. Afterward, check around the oil filter and drain plug for any signs of leaks.

If there are no leaks, turn off the engine and clean up your work area. Use rags or paper towels to wipe away any oil spills and keep your tools organized.

Dispose of the used oil properly by taking it to a recycling center or auto parts store. Never pour used oil down the drain or throw it away, as it is harmful to the environment.
