Hey guys! So, you've got a 2021 Ford Explorer ST, a seriously sweet ride, and you're probably thinking about keeping it running like a top. One of the most important things you can do for your Explorer ST is regular oil changes. It's like giving your engine a fresh start, ensuring it runs smoothly and lasts for years to come. In this guide, we'll break down everything you need to know about a 2021 Ford Explorer ST oil change, from the type of oil to use, the tools you'll need, the step-by-step process, and some helpful tips to make the job easier. Let's dive in!

Why Regular Oil Changes Matter for Your 2021 Ford Explorer ST

Alright, first things first, why is an oil change so crucial? Think of your engine oil as the lifeblood of your vehicle. It does a lot of important things: it lubricates all the moving parts, reducing friction and wear; it cools the engine by carrying away heat; it cleans the engine by removing dirt and debris; and it helps seal the gaps between pistons and cylinders, maximizing compression. Over time, the oil breaks down, gets contaminated, and loses its ability to perform these essential functions. This can lead to increased engine wear, reduced fuel efficiency, and even catastrophic engine failure.

For your 2021 Ford Explorer ST, which packs a punch with its powerful engine, regular oil changes are even more critical. The high-performance nature of the ST means the engine works harder, generates more heat, and puts more stress on the oil. Following the manufacturer's recommended oil change intervals and using the correct type of oil is key to keeping your ST running at its best. Ignoring oil changes is a recipe for expensive repairs down the road, so trust me, it's worth the small investment of time and money.

What You'll Need for the 2021 Ford Explorer ST Oil Change

Okay, before you get your hands dirty, let's gather all the stuff you'll need. This will make the process much smoother and prevent any frustrating trips to the auto parts store mid-job. Here's a checklist of everything you'll need for your 2021 Ford Explorer ST oil change:

• New Oil: The 2021 Ford Explorer ST requires 6.0 quarts of 5W-30 full synthetic oil. Always check your owner's manual for the most accurate specifications, but this is a pretty safe bet. Using full synthetic oil is highly recommended for the ST's high-performance engine. It provides better protection against heat and wear compared to conventional oil.
• Oil Filter: You'll need a new oil filter specifically designed for your Explorer ST. Make sure you get the right one! It's usually easy to find the correct filter by looking up your vehicle's make, model, and year at an auto parts store.
• Wrench or Socket: You'll need the right size wrench or socket to remove the oil drain plug. The size usually varies, but it's typically around 15mm or 16mm. A socket wrench with an extension can be helpful for reaching the plug.
• Oil Filter Wrench: This is a special tool designed to remove the oil filter. There are several types available, including cap-style wrenches and strap wrenches. Choose one that fits your filter and is easy to use.
• Drain Pan: You'll need a drain pan to catch the old oil as it drains from the engine. Make sure the pan is large enough to hold at least 6 quarts of oil.
• Funnel: A funnel will help you pour the new oil into the engine without making a mess.
• Jack and Jack Stands (Optional, but Recommended): While you might be able to squeeze under the Explorer ST without lifting it, it's much safer and easier to work on if the vehicle is raised. Always use jack stands to support the vehicle after jacking it up.
• Gloves: Protect your hands! Oil can be messy and can irritate your skin.
• Rags or Paper Towels: For wiping up spills and cleaning up.
• Wheel Chocks: For added safety, chock the rear wheels while the vehicle is raised.

Step-by-Step Guide to Changing the Oil in Your 2021 Ford Explorer ST

Now, let's get down to the nitty-gritty and walk through the oil change process step-by-step. Follow these instructions carefully, and you'll have fresh, clean oil in your ST in no time.

1. Prepare the Vehicle: Park your Explorer ST on a level surface and engage the parking brake. If you're going to use a jack and jack stands, chock the rear wheels for added safety. It's a good idea to warm up the engine for a few minutes before starting the oil change. This will help the oil flow more easily. However, be careful, the engine components will be hot!
2. Raise the Vehicle (If Necessary): If you're using a jack and jack stands, locate the jack points on your vehicle and carefully raise it. Place the jack stands under the frame in the designated areas and lower the vehicle onto the stands. Make sure the vehicle is stable before proceeding.
3. Locate the Oil Drain Plug: Crawl under the vehicle and locate the oil drain plug. It's usually on the bottom of the oil pan, which is located at the bottom of the engine. Consult your owner's manual if you're unsure.
4. Position the Drain Pan: Place the drain pan under the oil drain plug, making sure it's positioned to catch the oil as it drains.
5. Remove the Oil Drain Plug: Using the correct size wrench or socket, carefully loosen and remove the oil drain plug. Be prepared for the oil to start flowing out immediately. Let the oil drain completely, which may take 15-20 minutes.
6. Locate the Oil Filter: While the oil is draining, locate the oil filter. It's usually located near the engine block. Note the position of the filter so you can easily access it.
7. Remove the Oil Filter: Use the oil filter wrench to loosen and remove the oil filter. Be prepared for a small amount of oil to spill out as you remove the filter. Have a rag handy to wipe up any spills.
8. Prepare the New Oil Filter: Before installing the new oil filter, lubricate the rubber gasket on the new filter with a bit of fresh oil. This will help create a good seal. Also, make sure to check the old oil filter and make sure the gasket is not still stuck to the engine. If it is remove the gasket.
9. Install the New Oil Filter: Screw the new oil filter onto the engine by hand until the gasket makes contact. Then, tighten it according to the instructions on the filter, which usually means another half to three-quarters of a turn.
10. Reinstall the Oil Drain Plug: Once the oil has finished draining, clean the oil drain plug and reinstall it. Tighten the plug to the manufacturer's recommended torque specification. Again, check your owner's manual for this spec.
11. Lower the Vehicle: If you raised the vehicle, carefully lower it back to the ground.
12. Add New Oil: Locate the oil fill cap on top of the engine. Remove the cap and insert the funnel. Pour the correct amount of new oil into the engine (6.0 quarts for the 2021 Explorer ST). Keep an eye on the oil level using the dipstick to ensure you don't overfill the engine.
13. Check the Oil Level: After adding the oil, start the engine and let it run for a minute or two. This will allow the oil to circulate. Turn off the engine and let it sit for a few minutes. Then, check the oil level using the dipstick. Add more oil if needed to bring the level up to the full mark.
14. Check for Leaks: After running the engine, check for any leaks around the oil drain plug and the oil filter. If you see any leaks, tighten the plug or filter as needed.
15. Reset the Oil Life Monitor: Your Explorer ST has an oil life monitor that tracks the condition of your oil. After changing the oil, you'll need to reset the monitor. The procedure varies depending on your vehicle's features, so consult your owner's manual for specific instructions.
16. Dispose of the Old Oil and Filter: Properly dispose of the used oil and oil filter at a recycling center or auto parts store. Never pour oil down the drain or into the environment.

• Double-Check Your Work: Before starting the engine, double-check that the oil drain plug and oil filter are securely in place and that you've added the correct amount of oil.
• Consider a Ramp or Ramps: Ramps can make it easier to get under the vehicle without jacking it up. However, make sure the ramps are rated for the weight of your vehicle and that you use them safely.
• Have a Friend Help: Having a friend assist you can make the job easier and safer, especially if you're not used to working on cars.
