Can You Change Your Own Oil? What You Need to Know Before You Start

Is a DIY Oil Change Right for You?

Changing your own oil can be a rewarding project if you have basic mechanical skills and the right tools. Not everyone needs to do this work themselves—many people prefer to take their vehicle to a professional. This guide walks through what's involved so you can decide if it's something you want to tackle.

Before you commit to doing this work yourself, think about your comfort level working under a vehicle, your access to proper tools, and whether you have a safe workspace. Some vehicles make this job straightforward, while others have tight engine compartments or hard-to-reach components. Understanding what the process looks like will help you make an informed decision about whether to proceed.

What You'll Need to get your free guide

Before you begin, gather these items:

• A socket wrench set (to remove the drain plug)
• An oil filter wrench (to remove the old filter)
• A drain pan (to catch used oil)
• New oil (the type and amount your vehicle needs)
• A new oil filter
• Jack and jack stands (to safely lift your vehicle)
• Ramps (an alternative to a jack)
• A funnel (to pour new oil)
• Gloves and shop towels

You'll also want to check your vehicle's owner's manual to find the exact oil type, filter size, and drain plug location. The manual tells you how much oil your engine holds and where each component is located. Having this information before you start saves time and prevents mistakes. If you don't have a physical manual, most manufacturers provide free access online through their websites.

Safety First: Preparing Your Vehicle

Safety is the most important part of any DIY maintenance. Working on your vehicle involves hot oil, heavy equipment, and moving parts, so taking precautions protects you from injury:

• Work on a level, flat surface away from traffic
• Let your engine cool for several minutes before starting (hot oil can burn you)
• Never work under a vehicle supported only by a jack—always use jack stands
• Wear gloves to protect your hands from hot oil and sharp edges
• Keep a fire extinguisher nearby, just in case
• Tell someone else what you're doing and where you are
• Keep your phone within reach in case of emergency

The most common injury during an oil change happens when someone works under a vehicle that isn't properly supported. A jack can fail or slip, causing serious injury or death. Jack stands are designed to hold a vehicle safely even if the jack fails. Always use both a jack to lift and jack stands to support—never rely on a jack alone. If you're uncomfortable with this setup, using ramps is a safer alternative for many vehicles.

The Basic Steps

Lift your vehicle safely. Use a jack and jack stands, or drive onto ramps. Make sure your vehicle is secure and won't roll. Double-check that the parking brake is set and the engine is off.

Locate and remove the drain plug. This is usually a bolt on the bottom of the oil pan. Place your drain pan underneath, then unscrew the plug by hand or with a wrench. Let the old oil drain completely—this may take 10 to 15 minutes. The oil will be hot if the engine was recently running, so move slowly and carefully to avoid splashing.

Replace the drain plug. Once the oil stops dripping, wipe the plug clean with a shop towel and screw it back in. Don't overtighten it, or you may damage the threads. Hand-tight is usually sufficient, though you can use a wrench to snug it slightly if needed.

Remove the old oil filter. Use your oil filter wrench to loosen it, then unscrew it by hand. Be careful—there's still oil inside. Let it drain into your pan. Some oil will spill, so have towels ready.

Install the new filter. Wipe the filter mounting surface clean with a shop towel. Apply a thin layer of new oil to the rubber gasket on the new filter, then screw it on by hand until it's snug. Don't use a wrench to tighten it—hand-tight is the correct way to install a filter.

Add new oil. Lower your vehicle back to the ground. Open the oil filler cap on top of the engine and pour in the new oil using a funnel. Add a little less than the full amount, then check the dipstick to see if you're at the right level. The dipstick usually has marks showing minimum and maximum levels.

Check your work. Start the engine and let it run for a minute, then turn it off. Wait a few minutes and check the dipstick again to make sure the level is correct. The oil should be between the minimum and maximum marks. If it's too low, add a small amount and check again.

Understanding Oil Types and Viscosity

Not all oil is the same. Your owner's manual specifies the oil type and viscosity your engine needs. Common viscosities include 5W-30, 10W-40, and 0W-20. The first number (with the "W" for winter) tells you how the oil flows in cold weather, while the second number describes flow at normal operating temperature. Using the wrong oil can affect engine performance and longevity.

Synthetic oil, conventional oil, and synthetic blends all have different properties and price points. Synthetic oil lasts longer between changes but costs more upfront. Conventional oil is cheaper but requires more frequent changes. Your manual will recommend which type is suitable for your vehicle. Following these recommendations ensures your engine gets the protection it needs.

Disposing of Used Oil Properly

Never pour used oil down the drain or onto the ground. Used oil is toxic and harms the environment. Instead, take it to a location that accepts used oil:

• Local recycling centers
• Many auto parts stores (often for free)
• Municipal hazardous waste collection events
• Quick-lube shops (some accept oil even if you didn't do business with them)

Call ahead to confirm they accept used oil before you go. Most places will take it in any container, though some prefer sealed bottles or buckets. Keep your used oil in a clean, labeled container until you can drop it off. Proper disposal protects groundwater and soil in your community.

When to Call a Professional

A DIY oil change may not be the right choice if:

• Your vehicle is very low to the ground and hard to access underneath
• The drain plug or filter is in an awkward location
• You don't have a safe, level place to work
• You're not comfortable working under a vehicle
• Something doesn't feel right during the process
• Your vehicle has special drain requirements or a complex filter system

Professional mechanics have the tools, experience, and workspace to handle tricky situations quickly and safely. The cost of professional service is often reasonable compared to the time and effort required to do it yourself, especially if your vehicle has a complicated layout.

Key Takeaways

Changing your own oil is possible if you have the right tools, a safe workspace, and basic mechanical confidence. The process involves draining old oil, replacing the filter, and adding new oil. Always prioritize safety by using proper lifting equipment and letting your engine cool. Dispose of used oil responsibly, and don't hesitate to seek professional help if you run into problems or feel uncomfortable at any point.

Frequently Asked Questions

How often should I change my oil?

Oil change intervals depend on your vehicle's age, engine type, and the oil you use. Older vehicles with conventional oil typically need changes every 3,000 to 5,000 miles. Newer vehicles and those using synthetic oil may go 7,500 to 10,000 miles or longer between changes. Check your owner's manual for the manufacturer's recommendation for your specific vehicle. Following the recommended schedule helps keep your engine running smoothly.

What should I do if I spill oil on my driveway?

Oil spills can stain concrete and harm the environment. If you spill oil, cover it immediately with cat litter, sand, or a commercial absorbent product to prevent it from spreading. Let it sit for several hours, then sweep it up and dispose of it properly. For larger spills, contact your local environmental agency for guidance. Prevention is easier than cleanup, so work carefully and keep absorbent materials on hand before you start.

Can I reuse the old oil drain pan for other purposes?

It's best to keep your drain pan dedicated to oil changes. Even after rinsing, residual oil can contaminate other materials or liquids you might store in it. Used oil is hazardous, so any container that held it should be treated as a hazardous waste container. Label your drain pan clearly and store it in a safe place where it won't be confused with other tools or containers.

What's the difference between synthetic and conventional oil?

Conventional oil comes directly from crude oil and breaks down faster over time. Synthetic oil is chemically engineered to last longer and perform better in extreme temperatures. Synthetic oil costs more but requires fewer changes, which can save money over time. Some newer vehicles require synthetic oil, while others run fine on conventional. Your owner's manual specifies which type your engine needs.
