How to Change Your Buick Verano's Oil: A Step-by-Step Guide

Why Regular Oil Changes Matter

Oil keeps your Verano's engine running smoothly by reducing friction between moving parts. Over time, oil breaks down and collects dirt and debris. Changing your oil on schedule helps your engine last longer and run better. Fresh oil also helps your engine stay cool and protects it from rust and corrosion.

Neglecting oil changes can lead to serious engine damage. Dirty oil becomes thick and sticky, making it harder for your engine to work. This extra strain can shorten your engine's life and lead to costly repairs down the road. Regular maintenance is one of the best ways to keep your Verano running strong for years to come.

What You'll Need

Before you start, gather these items to make the job easier and safer:

• New oil (check your owner's manual for the correct type and amount)
• New oil filter
• Oil drain pan
• Wrench or socket set
• Oil filter wrench
• Jack and jack stands (if you need to raise your vehicle)
• Rags or paper towels
• Safety glasses
• Gloves to protect your hands
• Newspaper or cardboard to catch spills

Having everything ready before you begin saves time and prevents frustration. Most of these tools are inexpensive and useful for other vehicle maintenance tasks. If you don't own some items, you can borrow them from friends or rent them from auto parts stores.

Step 1: Warm Up Your Engine

Start your Verano and let it run for a few minutes. Warm oil flows better than cold oil, so it drains more completely. This also helps loosen any buildup inside the engine. Then turn off the engine and wait a couple of minutes before proceeding—this gives the oil time to settle but keeps it warm enough to flow easily.

Never work on a hot engine. Wait long enough that you can touch the engine block without burning yourself. The oil inside will still be warm enough to drain well, but the metal parts won't be dangerously hot. This balance between warm oil and a safe working temperature is important for both the job and your safety.

Step 2: Raise Your Vehicle (If Needed)

If you need more room to work underneath, use a jack to raise your Verano. Always use jack stands for safety—never rely on a jack alone. A jack can fail, and a falling vehicle is extremely dangerous. Place the jack stands on solid, level ground and position them under sturdy parts of your vehicle's frame.

If your Verano sits high enough off the ground and you can fit comfortably underneath, you may not need to raise it at all. Check that you have enough space to reach the drain plug and oil filter without straining or putting yourself in an unsafe position. Working in a well-lit area with proper lighting helps you see what you're doing and work more safely.

Step 3: Locate and Remove the Drain Plug

Look under your engine for the oil drain plug—it's a bolt sticking out from the bottom of the oil pan. Your owner's manual shows exactly where it is. Place your drain pan underneath it to catch the old oil. Use your wrench to loosen the plug by turning it counterclockwise. Once it's loose enough, carefully unscrew it by hand. Be careful—the oil may still be warm.

Let the old oil drain completely into the pan. This may take several minutes, so be patient. While you're waiting, you can prepare other items or review the next steps. Draining all the old oil is important because leaving dirty oil in your engine defeats the purpose of the oil change. Once the flow slows to just a few drips, you can move on to the next step.

Step 4: Replace the Drain Plug

Wipe off the drain plug with a rag to remove any oil and debris. Look at the plug's rubber washer—if it's damaged or worn, replace it with a new one. A good seal prevents leaks. Screw the plug back in by hand first to avoid cross-threading, then tighten it with your wrench. Don't over-tighten it, as this can damage the threads or crush the washer.

The drain plug should be snug but not extremely tight. A good rule is to tighten it firmly but stop before you feel serious resistance. If you over-tighten and strip the threads, you'll have a bigger problem on your hands. Once it's secure, wipe away any spilled oil from the pan and surrounding area.

Step 5: Replace the Oil Filter

Find your oil filter—your owner's manual shows where it is located on your engine. It's usually a cylindrical canister about the size of a soda can. Place your drain pan underneath to catch any remaining oil that will spill when you remove the filter. Use an oil filter wrench to loosen it by turning counterclockwise. Once loose, unscrew it by hand and set it aside. Wipe the filter mounting surface clean with a rag to remove any dirt or old rubber pieces.

Apply a thin layer of new oil to the rubber seal on your new filter. This helps create a good seal and makes removal easier next time. Screw the new filter on by hand until the rubber seal touches the mounting surface, then turn it about three-quarters of a turn more. This is the correct amount of tightness. Don't use a wrench for the new filter—hand-tight is all you need. Over-tightening can damage the filter and make it hard to remove later.

Step 6: Add New Oil

Locate your oil filler cap on top of the engine and unscrew it. This is usually labeled with an oil can symbol. Pour in the amount of new oil recommended in your owner's manual. Most Veranos need between 4 and 6 quarts, but always check your manual to be sure. Pour slowly and carefully to avoid spills. Replace the cap when you're done.

Using the correct type and amount of oil is crucial. Your manual specifies the oil viscosity—the thickness rating like 5W-30 or 10W-40. Using the wrong type can affect your engine's performance and protection. The correct amount ensures your engine has enough oil to circulate properly without overfilling, which can cause problems of its own.

Step 7: Check Your Work

Start your engine and let it run for about a minute. Watch for any leaks around the drain plug or filter. The oil pressure light on your dashboard should come on briefly, then turn off once the new oil circulates. This is normal. Turn off the engine and wait a few minutes for the oil to settle in the pan.

Pull out the dipstick and wipe it clean with a rag. Reinsert it fully into its tube, then pull it out again to check the oil level. The oil should reach the full mark on the stick. If it's low, add a little more oil and check again. Getting the level right is important—too little oil can damage your engine, and too much can cause problems too. Once the level is correct, you're done with this step.

Step 8: Clean Up and Disposal

Lower your vehicle if you raised it. Make sure everything is secure and the vehicle sits level on the ground. Wipe up any spilled oil with rags or paper towels. Dispose of your old oil properly—most auto parts stores and service stations will take it for free. Don't pour it down the drain or into the ground, as it's harmful to the environment and often illegal.

Store your used oil in a clean container until you can take it to a recycling center or auto parts store. Many places that sell oil will take your old oil at no charge when you buy new oil from them. Some communities also have hazardous waste collection days where you can drop off used oil. Proper disposal is not just good for the environment—it's the responsible thing to do.

How Often to Change Oil

Check your owner's manual for your Verano's recommended oil change schedule. Most vehicles need an oil change every 3,000 to 10,000 miles, depending on your engine type and the oil you use. Synthetic oil often lasts longer than conventional oil, so if you use synthetic, you may be able to go longer between changes.

Keep track of your oil changes by noting the date and mileage each time you do one. Some vehicles have an oil change reminder light that alerts you when service is due. Staying on schedule helps your engine stay clean and healthy. If you drive in severe conditions—like frequent short trips, towing, or dusty environments—you may need to change your oil more often than the standard schedule suggests.

Frequently Asked Questions

What happens if I use the wrong type of oil in my Verano?

Using the wrong oil viscosity can affect how well your engine is protected and how efficiently it runs. Oil that's too thick won't flow properly in cold weather, while oil that's too thin won't provide enough protection in hot conditions. Always use the type specified in your owner's manual. If you accidentally use the wrong oil, you can change it again to correct the mistake.

Can I change my oil without raising my vehicle?

It depends on how much clearance your Verano has under the engine. If you can fit comfortably underneath and reach the drain plug and filter without straining, you don't need to raise it. However, many people find that raising the vehicle makes the job easier and safer. If you do raise it, always use jack stands—never work under a vehicle supported only by a jack.

How do I know if my oil filter is on tight enough?

Hand-tighten the new filter until the rubber seal touches the mounting surface, then turn it about three-quarters of a turn more. This is the correct amount of tightness. You shouldn't need a wrench for this—if you do, you've probably over-tightened it. Over-tightening makes it hard to remove next time and can damage the filter. A properly installed filter will be snug but not extremely tight.

What should I do if I spill oil on the ground?

Clean up oil spills right away to prevent environmental damage and keep your workspace safe. Use rags, paper towels, or absorbent material like kitty litter to soak up the oil. Dispose of the contaminated materials in a sealed bag. If a large amount of oil spills, you may need to use an absorbent product designed for oil spills. Never let oil drain into storm drains or onto soil, as this harms the environment.
