Getting Ready to Change the Oil in Your Buick Envista
Changing your oil is an important part of vehicle maintenance. It keeps your engine clean, prevents wear, and helps your 2025 Buick Envista run smoothly. If you’re planning to do the job yourself, preparation is key. Before you begin, make sure you have everything you need. This will save time and make the process easier.

What You’ll Need
Before starting, gather the right tools and supplies. Here’s what you’ll need for a smooth oil change:
  • Fresh Motor Oil – Check your owner’s manual to find the right type and amount of oil for your vehicle.
  • New Oil Filter – A fresh filter is necessary to keep your engine running clean.
  • Wrench Set – You’ll need a wrench to remove and tighten the drain plug.
  • Oil Catch Pan – This will collect the used oil so you can dispose of it properly.
  • Funnel – Helps you pour new oil without making a mess.
  • Gloves and Rags – Oil can get messy, so gloves protect your hands while rags help clean spills.
  • Jack and Jack Stands (if needed) – If your vehicle sits low to the ground, you may need to lift it for better access.

Safety First
  • Oil changes are simple, but safety should always come first. Keep these safety tips in mind:
  • Park on a Level Surface – This keeps your car stable and prevents spills.
  • Turn Off the Engine – Let it cool for about 15 minutes to avoid burns from hot oil.
  • Engage the Parking Brake – This ensures your car stays in place while you work.
  • Use Jack Stands If Lifting the Vehicle – Never rely on just a jack. Always use jack stands for extra safety.
Taking time to prepare will make your 2025 Buick Envista oil change easier and help prevent mistakes. Once you have everything ready, it’s time to locate the oil drain plug and filter.

Locating the Oil Drain Plug and Filter on Your Buick Envista
To change the oil, you need to find two key parts: the oil drain plug and the oil filter. Both are located under your vehicle and are essential for removing the old oil.

Where to Find Them
  • Oil Drain Plug – This is a small metal bolt located on the bottom of the engine’s oil pan. It allows the old oil to drain out when removed.
  • Oil Filter – The filter is usually a round, canister-shaped part near the engine. It traps dirt and debris to keep oil clean.

How to Access Them
  • If your Buick Envista DIY oil change requires more space, raise the vehicle using a jack and secure it with jack stands.
  • Use a flashlight to get a clear view of the drain plug and filter.
  • Position your oil catch pan under the drain plug before loosening it to avoid spills.
Once you’ve located these parts, you’re ready to drain the old oil.

Draining the Old Oil from Your Buick Envista
Removing the old oil is a crucial step in the process. Proper draining ensures that your engine gets fresh, clean oil. Follow these steps to do it correctly.

Step-by-Step Guide
  1. Place the Oil Catch Pan – Position it directly under the drain plug to catch all the oil.
  2. Loosen the Drain Plug – Use a wrench to turn the plug counterclockwise. Be careful, as oil may start flowing quickly.
  3. Let the Oil Drain Completely – Wait until the oil slows to a few drips before moving to the next step. This may take a few minutes.
  4. Inspect the Drain Plug and Oil Pan – Check for dirt or damage on the plug. Wipe the area clean before reattaching it.
  5. Reinstall the Drain Plug – Tighten it securely but do not overtighten, as this can strip the threads.

Pro Tips for a Clean Oil Change
  • Warm oil drains faster. If your engine is slightly warm (but not hot), the oil will flow more easily.
  • Be careful of spills. Old oil can be messy, so keep rags nearby.
  • Check for leaks. Before moving on, ensure the drain plug is sealed properly.
Once the old oil is fully drained, the next step is replacing the oil filter.

Replacing the Oil Filter in Your Buick Envista
The oil filter plays a key role in keeping your engine clean. A fresh filter removes dirt and debris from the oil, helping your engine run longer and more efficiently.

How to Change the Oil Filter
  1. Locate the Old Filter – It is usually near the engine, either on the side or bottom.
  2. Use an Oil Filter Wrench – Turn the old filter counterclockwise to loosen it. Be careful—some oil may still be inside.
  3. Check the Rubber Gasket – Make sure the rubber seal from the old filter came off. If it’s stuck, remove it.
  4. Prepare the New Filter – Apply a small amount of fresh oil to the rubber seal. This helps create a tight seal.
  5. Install the New Filter – Screw it on by hand until snug. Avoid using a wrench, as overtightening can cause leaks.

Why Replacing the Filter is Important
  • A dirty filter can clog and restrict oil flow.
  • New filters help your engine stay clean and run efficiently.
  • Changing the filter prevents old oil from contaminating fresh oil.
With the new filter in place, it’s time to add fresh oil to your engine.

Adding New Oil to Your Buick Envista
Fresh oil is the final step in your Buick Envista DIY oil change. Adding the correct type and amount of oil is crucial for your engine’s performance.

How to Add Oil
  1. Remove the Oil Fill Cap – It’s located on top of the engine. Turn it counterclockwise to open.
  2. Insert a Funnel – This helps you pour without making a mess.
  3. Pour the Correct Amount of Oil – Check your owner’s manual for the required oil capacity. Add it slowly.
  4. Check the Oil Level – Use the dipstick to ensure you’ve added enough oil.
  5. Replace the Oil Cap – Tighten it securely to prevent leaks.

Final Checks Before You’re Done
  • Start the engine and let it run for about a minute. This allows the new oil to circulate.
  • Look under the vehicle for any leaks near the drain plug or filter.
  • Turn off the engine and check the oil level again. If needed, add more oil.

Checking the Oil Level in Your Buick Envista
After changing the oil, it’s important to check the level. This ensures the engine has the right amount for smooth performance. Checking the oil is simple and only takes a few minutes.

How to Check the Oil Level
Follow these steps to make sure your oil level is correct:
  1. Park on a Level Surface – This gives the most accurate reading.
  2. Turn Off the Engine – Wait a few minutes so the oil can settle.
  3. Locate the Dipstick – It’s usually near the engine and has a small handle.
  4. Pull Out the Dipstick – Wipe it clean with a rag or paper towel.
  5. Reinsert the Dipstick – Push it all the way back in, then pull it out again.
  6. Check the Oil Level – Look at the markings on the dipstick. The oil should be between the “MIN” and “MAX” lines.
  7. Add More Oil If Needed – If the level is low, add a small amount at a time and recheck.

What the Oil Should Look Like
  • Clean Oil – Light brown and smooth.
  • Dirty Oil – Dark and thick, which means it’s time for a change.
  • Milky Oil – Could signal a bigger issue like coolant mixing with oil.
Keeping the right oil level helps prevent engine damage. It also keeps your car running at its best.

Proper Disposal of Old Oil and Oil Filter
Used oil and filters should never be thrown in the trash or poured down a drain. They contain harmful chemicals that can pollute the environment. After completing a 2025 Buick Envista oil change, follow these steps to dispose of the waste properly.

How to Handle Used Oil
  • Use a Sealable Container – Pour the old oil into a clean plastic or metal container with a secure lid.
  • Do Not Mix with Other Fluids – Keep it separate from coolant, brake fluid, or other substances.
  • Store Safely – Keep the container in a cool, dry place until you can dispose of it properly.

How to Dispose of the Oil Filter
  • Let It Drain – Place the old filter upside down over the catch pan for at least 24 hours to remove excess oil.
  • Seal in a Leak-Proof Bag – Once drained, place the filter in a sturdy plastic bag to prevent spills.
  • Recycle It – Many auto shops, service stations, and recycling centers accept used oil filters.

Where to Take Used Oil and Filters
There are several places that accept used oil and filters for proper disposal. Many auto parts stores allow free drop-offs, but it’s always best to call ahead and confirm. Local recycling centers often have special collection areas for oil waste, and city websites usually list drop-off locations. Some service stations also accept used oil and filters, though they may charge a small fee.

By disposing of oil and filters correctly, you help protect the environment and keep harmful waste out of landfills. Always take the time to recycle and follow proper disposal steps.

Resetting the Oil Change Light in Your Buick Envista
After completing a Buick Envista DIY oil change, you may need to reset the oil change light. This reminder is helpful, but once the oil is fresh, it needs to be turned off.

Steps to Reset the Oil Change Light on Your Buick Envision
  1. Turn the Ignition to “On” – Do not start the engine.
  2. Access the Vehicle’s Info Menu – Use the buttons on the steering wheel.
  3. Find the Oil Life Option – Scroll until you see the oil life percentage.
  4. Hold the Reset Button – Press and hold for a few seconds until it resets to 100%.
  5. Turn the Ignition Off and Restart – The light should be gone.
If the light stays on, repeat the steps or check the owner’s manual.

Keeping track of oil changes helps your car run well. Resetting the light ensures you get a new reminder at the right time.

Additional Tips for Maintaining Your Buick Envista’s Engine Health
