Hey there, car enthusiasts! If you're the proud owner of a 2021 Ford Explorer ST, you know it's not just an SUV; it's a performance machine. And like any high-performance vehicle, regular maintenance, especially oil changes, is crucial to keep it running smoothly. So, let's dive into everything you need to know about performing an oil change on your 2021 Ford Explorer ST.

Why is Regular Oil Changes Important?

Before we get our hands dirty, let's talk about why oil changes are so important. Your engine oil is the lifeblood of your Explorer ST. It lubricates the engine's moving parts, reduces friction, dissipates heat, and cleans away dirt and debris. Over time, oil breaks down and becomes contaminated, losing its ability to protect your engine effectively. That's where regular oil changes come in. By changing your oil at the recommended intervals, you're ensuring that your engine stays clean, cool, and properly lubricated, which can extend its lifespan and prevent costly repairs. Think of it as giving your engine a refreshing spa day! The frequency of oil changes depends on various factors, including your driving habits, the type of oil you use, and the manufacturer's recommendations.

Ford recommends specific oil change intervals for the 2021 Explorer ST to maintain optimal engine performance and longevity. These intervals are typically based on mileage or time, whichever comes first. For most driving conditions, Ford suggests changing the oil every 7,500 to 10,000 miles, or at least once a year. However, if you frequently engage in severe driving conditions, such as towing heavy loads, driving in extreme temperatures, or participating in stop-and-go traffic, you may need to change the oil more frequently, possibly every 5,000 to 7,500 miles. Neglecting regular oil changes can lead to a buildup of sludge and deposits in the engine, reducing its efficiency and potentially causing significant damage over time. Additionally, using the correct type of oil, as specified by Ford, is crucial for maintaining warranty coverage and ensuring proper engine lubrication. Consulting your owner's manual for the recommended oil type and change intervals is always a good practice.

What You'll Need

Alright, let's gather our tools and supplies. Here’s a checklist of what you’ll need for your 2021 Ford Explorer ST oil change:

• New Oil: Check your owner's manual to confirm the correct type and quantity. For the 2021 Explorer ST, you'll likely need around 6 quarts of full synthetic oil, often 5W-30, but always verify. Using the right oil is critical for the engine's performance and longevity.
• New Oil Filter: Again, consult your owner's manual or a parts store to get the correct oil filter for your vehicle.
• Wrench: You'll need a wrench to remove the oil drain plug. Make sure you have the right size! A 15mm wrench usually works, but double-check.

Step-by-Step Guide

Okay, now for the fun part! Here’s a step-by-step guide to changing the oil in your 2021 Ford Explorer ST. Safety first, guys! Make sure you're working in a well-ventilated area and take all necessary precautions.

1. Prepare Your Vehicle

• Warm Up the Engine: Run the engine for a few minutes to warm the oil. Warm oil flows more easily.
• Safely Lift the Vehicle: Park your Explorer ST on a level surface. Engage the parking brake and use wheel chocks behind the rear wheels. Use a jack to lift the front of the vehicle and securely place jack stands under the frame rails. Never work under a vehicle supported only by a jack! Alternatively, you can use ramps if you have them.

2. Locate and Remove the Drain Plug

• Locate the Oil Pan: Find the oil pan underneath the engine. It's usually a large, metal pan at the bottom of the engine.
• Position the Drain Pan: Place the drain pan directly under the oil drain plug.
• Remove the Drain Plug: Use your wrench to carefully loosen and remove the drain plug. Be prepared for the oil to flow out quickly. Let the oil drain completely. This might take 15-20 minutes.

3. Remove the Old Oil Filter

• Locate the Oil Filter: The oil filter is usually located near the front of the engine. Consult your owner's manual if you're unsure.
• Loosen the Oil Filter: Use your oil filter wrench to loosen the old oil filter. Have your drain pan in place as some oil will spill out.
• Remove the Oil Filter: Unscrew the oil filter by hand. Make sure the rubber gasket comes off with the filter. If it sticks to the engine, carefully remove it.

4. Install the New Oil Filter

• Lubricate the Gasket: Lightly lubricate the rubber gasket on the new oil filter with fresh oil. This helps create a good seal.
• Install the New Filter: Screw the new oil filter onto the engine by hand until the gasket makes contact. Then, tighten it an additional ¾ turn, or according to the filter's instructions. Don't overtighten!.

5. Reinstall the Drain Plug

• Clean the Drain Plug: Clean the drain plug and inspect the washer. Replace the washer if it's damaged.
• Reinstall the Drain Plug: Reinstall the drain plug and tighten it to the manufacturer's specified torque. Again, don't overtighten! Typically around 18-22 lb-ft

6. Add New Oil

• Locate the Oil Fill Cap: Find the oil fill cap on top of the engine. It usually has an oil can symbol on it.
• Add New Oil: Use a funnel to pour the correct amount of new oil into the engine. Refer to your owner's manual for the exact quantity. For the 2021 Explorer ST, it's usually around 6 quarts.
• Check the Oil Level: Use the dipstick to check the oil level. Add more oil if needed to reach the
