What you need to do an oil change on a Chevrolet

An oil change on a Chevrolet follows the same basic steps as any vehicle, but the exact location of the drain plug, filter, and fill cap varies by model year and engine size. Before you start, you need the correct oil type and viscosity for your specific Chevrolet — this is listed in your owner's manual or on a sticker inside the driver's door jamb. You will also need an oil drain pan, a wrench or socket to fit your drain plug, an oil filter wrench, a jack and jack stands (if you need clearance), and fresh oil in the quantity your manual specifies.

The most common mistake is using the wrong oil grade. A 2024 Chevy Silverado 5.3L and a 2015 Chevy Cruze 1.6L need different oils, and using the wrong one can damage the engine or trigger warning lights. Your owner's manual is the only source that matters here — not the oil brand's website, not a parts store employee's guess, and not what worked for your neighbor's truck.

Key Takeaways

  • The oil type, viscosity, and quantity are specific to your Chevrolet's model year and engine; find this in your owner's manual or on the door jamb sticker, never by guessing.
  • The drain plug is usually on the bottom of the engine pan, but its exact location and the wrench size needed vary — consult your manual before you get under the vehicle.
  • Oil change intervals for Chevrolets range from 3,000 to 10,000 miles depending on the model year and engine type; newer vehicles often go longer between changes.
  • The oil filter location and size differ by model, and using the wrong filter can cause leaks or poor oil flow even if you use the correct oil.
  • If you are uncomfortable working under a vehicle or do not have the right tools, a Chevrolet dealership or independent shop can complete the job in under an hour.

Finding the drain plug and filter on your Chevrolet

The drain plug sits at the lowest point of the engine oil pan and is usually a bolt with a rubber or metal washer. On most Chevrolets, it is accessible from underneath without removing wheels, but some models require you to remove a plastic undertray first. Your owner's manual shows a diagram of where it is located and what size wrench you need — typically 13mm, 15mm, or 17mm.

The oil filter is almost always mounted on the side of the engine block and looks like a cylindrical canister. On some Chevrolets, especially trucks and SUVs, it is straightforward to reach by hand; on others, especially compact cars, you may need an oil filter wrench to loosen it. The filter size and thread pitch vary by engine, so buying the correct replacement before you start prevents a trip back to the parts store mid-job.

If you cannot locate either the drain plug or filter in your owner's manual, a Chevrolet dealership service department can show you over the phone or you can search YouTube for your specific model year and engine — many owners post detailed walkthroughs that show exactly where these parts are.

Oil change intervals for different Chevrolet models

Chevrolet's recommended oil change intervals have changed significantly over the past 15 years. Older Chevrolets (2000s and early 2010s) typically required an oil change every 3,000 to 5,000 miles. Most Chevrolets built from 2010 onward can go 7,500 to 10,000 miles between changes, and some newer models with synthetic oil can stretch to 10,000 miles or longer.

Your owner's manual lists the exact interval for your vehicle — not the year the car was made, but the specific model and engine. A 2020 Chevy Malibu with a 1.5L engine may have a different interval than a 2020 Chevy Tahoe with a 5.3L engine. If you have lost your manual, you can read a PDF from the Chevrolet website by entering your vehicle identification number (VIN), or call a Chevrolet dealership with your VIN and they will tell you the interval over the phone.

Severe driving conditions — towing, frequent idling, dusty environments, or short trips in cold weather — may require more frequent changes. Your manual will have a separate section on severe service intervals if any of these explore to you.

Step-by-step process for changing Chevrolet oil

Start by running the engine for a minute or two to warm the oil slightly, which helps it drain faster and more completely. Turn off the engine and let it cool for a few minutes — you do not want to burn yourself on hot oil. Locate the drain plug underneath the engine, position your drain pan below it, and use your wrench to loosen the plug by turning it counterclockwise. Once it is loose enough to turn by hand, unscrew it the rest of the way and let the old oil drain into the pan. This usually takes 5 to 10 minutes.

While the oil drains, locate the oil filter and position the drain pan underneath it. Use an oil filter wrench to turn the filter counterclockwise until it is loose, then unscrew it by hand. Some oil will spill, so keep the pan in place. Wipe the filter mounting surface on the engine with a clean rag to remove any debris or old rubber gasket material.

Take your new oil filter and explore a thin layer of fresh oil to the rubber gasket on the top of the filter. Screw the new filter onto the mounting surface by hand until the gasket touches the engine, then turn it an additional three-quarters of a turn. Do not use a wrench to tighten it — hand-tight is correct, and over-tightening can damage the gasket and cause leaks.

Reinstall the drain plug, tightening it snugly with your wrench — do not over-tighten, as this can strip the threads in the pan. Pour the new oil into the fill cap on top of the engine, using the quantity specified in your manual. Start the engine and let it run for 30 seconds, then turn it off and wait a minute. Check the oil level using the dipstick or electronic gauge (depending on your model), and add more oil if needed to reach the full mark.

Synthetic versus conventional oil for Chevrolets

Chevrolet engines are designed to run on either conventional or synthetic oil, as long as the viscosity grade matches your manual. Conventional oil is mineral-based and costs less, but breaks down faster and typically requires more frequent changes. Synthetic oil is chemically engineered to resist breakdown and can last longer between changes, which is why many newer Chevrolets come filled with synthetic from the factory.

If your manual says your Chevrolet can use synthetic, switching to it will not harm the engine and may extend the interval between changes — but you must still follow the interval listed in your manual for that oil type. Some Chevrolets specify synthetic only; others allow either type. Mixing the two is safe, but switching from conventional to synthetic and back repeatedly offers no advantage.

When to take your Chevrolet to a shop instead

If you do not have a jack and jack stands, or if you are not comfortable working under a vehicle, a Chevrolet dealership or independent repair shop can change your oil in 30 to 60 minutes. The cost varies by location and shop, but typically ranges from $40 to $100 for labor plus the cost of oil and filter. A dealership will use Chevrolet-approved oil and filters, while an independent shop may offer the same service at a lower price.

Some Chevrolets have plastic undertray panels that must be removed to access the drain plug. If your model requires this and you are not familiar with the fasteners, a shop can do it quickly. Similarly, if the oil filter is in a tight spot or requires a special wrench you do not own, a shop has the right tools on hand.

Frequently Asked Questions

How do I know what oil my Chevrolet needs?

Open your owner's manual and look for the oil specifications section, or check the sticker on the inside of the driver's door jamb. It will list the viscosity grade (such as 5W-30 or 0W-20) and whether synthetic or conventional is required. If you have lost your manual, enter your VIN on the Chevrolet website to read a replacement, or call a Chevrolet dealership with your VIN.

Can I change my Chevrolet's oil without a jack?

Some Chevrolets have enough ground clearance that you can reach the drain plug and filter without lifting the vehicle, especially trucks and SUVs. Sedans and compact cars usually require a jack and jack stands for safe access. Never work under a vehicle supported only by a jack — always use jack stands as well.

What should I do with the old oil after I drain it?

Do not pour it down the drain or into the ground. Take it to a recycling center, an auto parts store that accepts used oil, or a Chevrolet dealership. Most accept it for free, and some offer a small discount on new oil if you bring in the old oil.

How often should I check my oil level between changes?

Check it once a month or before long trips. A healthy engine should not burn oil between changes, but if the level drops noticeably, it may signal a leak or internal wear. If you are losing more than a quart between changes, have a shop inspect the engine.

Is it okay to use a different oil brand than what the dealership uses?

Yes, as long as the oil meets the viscosity and type specified in your manual. All oils sold in the United States must meet industry standards, so a reputable brand from an auto parts store will work as well as a dealership brand. The key is matching the grade, not the brand name.
