In this article, we’ll walk you through every step of the process, from gathering your tools to finishing up the job. Don’t worry—if you’ve never done it before, we’ll make sure you feel confident by the end!
What You Need Before You Start
Changing your engine oil is a relatively simple job, but it requires some basic tools and supplies. Before you dive into the task, it’s a good idea to gather everything you need to make the process easier and quicker.
Essential Tools and Supplies for Changing Engine Oil
First, let’s start by making sure you have everything you need to get started. The most important items are the right oil, a new oil filter, and a few basic tools. Here’s a list:
- Engine Oil: Make sure you get the right oil for your vehicle. Check the owner’s manual for the recommended oil type and quantity.
- Oil Filter: The oil filter should also be replaced each time you change the oil. It traps debris and particles to keep the oil clean.
- Drain Pan: This will catch the old oil as it drains out, preventing any mess.
- Wrenches and Socket Set: You’ll need a socket wrench to remove the drain plug and oil filter.
- Funnel: To avoid spilling oil when refilling, use a funnel.
- Gloves and Rags: For cleanliness and safety, wear gloves to protect your hands. Have rags on hand for any messes.
- Car Jack and Jack Stands: If your car is low to the ground, you’ll need to lift it using a jack and secure it with jack stands.
- Oil Filter Wrench: This tool helps remove the oil filter if it’s stuck or difficult to loosen by hand.
Make sure all the tools are in good condition before you begin. It can be a hassle to stop halfway through the job because something broke or wasn’t working correctly.
Choosing the Right Engine Oil
When choosing engine oil, it’s important to get the right type for your car’s make and model. The owner’s manual should provide the specifications. There are two main types of oil: conventional and synthetic. Conventional oil is cheaper but may require more frequent changes. Synthetic oil lasts longer and is better for high-performance engines. Both have their place, so choose based on your car’s needs and your budget.
Additionally, the oil viscosity rating is important. This is typically shown as numbers like 5W-30. The “W” stands for winter, and the number before it shows how well the oil flows in cold temperatures. The higher the number, the thicker the oil. Your car’s manual should tell you the recommended viscosity for your climate and driving conditions.
How to Drain the Old Oil
The first step in changing your engine oil is to drain out the old, used oil. This step is crucial because it removes the dirt, grime, and other contaminants that have built up in the oil over time.
Lifting the Car and Locating the Drain Plug
Before you start draining the oil, you need to lift the car so you can access the oil pan underneath. Use a car jack to lift the front of the car, and place jack stands underneath to ensure safety. Never rely solely on the jack to support the car while you’re working beneath it.
Once the car is lifted, slide underneath and locate the oil pan. The drain plug is typically located on the bottom of the pan. It’s usually a bolt that needs to be unscrewed to allow the oil to drain out. Take a moment to check the oil pan for any damage or leaks before proceeding.
Draining the Oil
Now that you’ve located the drain plug, it’s time to get your drain pan in place. Position the pan directly beneath the drain plug to catch the oil as it flows out. Using your socket wrench, unscrew the drain plug. Be cautious—if the engine has been running recently, the oil can be very hot. Let the oil drain for several minutes until it stops flowing.
It’s important to let the oil drain completely to ensure that no old oil remains in the engine. This helps maintain the quality of the new oil and keeps the engine running efficiently.
Removing the Drain Plug and Allowing the Oil to Cool
Once the oil has finished draining, take out the drain plug completely. Be careful, as the plug can be hot. Allow the oil to cool for a few minutes before handling the plug. After removing it, check the gasket on the plug to ensure it’s in good condition. If the gasket looks worn out or damaged, it’s a good idea to replace it before reattaching the plug.
While waiting for the oil to cool, you can start preparing to replace the oil filter.
Replacing the Oil Filter
Changing the oil filter is just as important as draining the old oil. The filter is responsible for keeping the oil clean by trapping dirt and debris. Over time, the filter can become clogged, so it’s necessary to replace it each time you change your oil.
Finding the Oil Filter and Preparing to Remove It
The oil filter is typically located near the oil pan, although its exact position can vary depending on the make and model of your car. In some cars, it may be easy to reach, while in others, it might require you to move some parts to gain access.
Once you’ve located the oil filter, use the oil filter wrench to loosen it. If it’s too tight to remove by hand, the wrench will give you extra leverage. Turn the filter counterclockwise to loosen it. Be careful as the oil inside the filter can spill out once you break the seal, so keep the drain pan close by.
Installing the New Oil Filter
Before you install the new filter, apply a small amount of clean oil to the rubber gasket on the top of the filter. This helps ensure a good seal when you install it. Screw the new filter onto the mounting point, turning it clockwise until it’s snug. Be careful not to overtighten the filter, as this can cause damage. Usually, hand-tightening is enough.
Once the filter is securely in place, wipe away any oil that may have spilled during removal or installation with a rag. You don’t want any oil leaking onto the engine after everything is reassembled.
Filling the Engine with New Oil
With the old oil drained and the new filter in place, it’s time to fill your engine with fresh oil. This is the final step in the process and ensures that your car runs smoothly for the next few thousand miles.
Opening the Oil Filler Cap
Locate the oil filler cap, which is usually found on top of the engine. It’s marked with an oil can symbol. Unscrew the cap and set it aside. You may need a funnel to help pour the oil without spilling it.
Adding the New Oil
Refer to your car’s manual to determine the amount and type of oil needed. Slowly pour the oil into the engine, checking the level frequently using the dipstick to avoid overfilling. You don’t want to add too much oil, as this can cause other engine problems. Once you’ve added the right amount, replace the filler cap securely.
Checking the Oil Level
After filling the engine with oil, check the level using the dipstick. Insert it back into the tube, pull it out, and wipe it clean with a rag. Reinsert the dipstick, pull it out again, and check the level. If it’s below the recommended level, add a little more oil until you reach the correct level.
If everything looks good, start the engine and let it run for a few minutes. This helps circulate the new oil throughout the engine. After turning off the engine, wait for a minute or two, then check the oil level again to make sure it’s correct. If necessary, top off the oil.
I hope this guide helps you feel confident about changing the engine oil in your car. It’s a simple task that can save you money and keep your car running smoothly for years to come. Just remember to follow each step carefully, and don’t rush through the process. With the right tools and some patience, you can handle it yourself.
Frequently Asked Questions (FAQs)
