With basic tools, about 30–45 minutes, and this step-by-step guide, you can safely and effectively change the oil in your 2008 Tucson yourself. Not only will you save money on labor costs, but you’ll also gain confidence in maintaining your vehicle.

In this guide, we’ll walk you through everything you need—from tools and materials to safety precautions, detailed steps, troubleshooting tips, and even how to reset your dashboard oil change reminder. Whether you’re a first-time DIYer or just need a refresher, this comprehensive tutorial will make the process smooth and stress-free.

Why Regular Oil Changes Matter

Your engine has hundreds of moving parts that generate heat and friction every time you drive. Motor oil acts like a protective shield, coating these components to reduce wear and tear. But as oil ages, it collects contaminants like metal shavings, carbon deposits, and moisture. These impurities reduce lubrication quality and can lead to sludge formation—especially in high-mileage engines like the 3.3L V6 found in the 2008 Tucson.

Sludge doesn’t just reduce performance—it can clog oil passages, starve critical components of lubrication, and eventually cause engine failure. Regular oil changes flush out these contaminants and replenish additives that help neutralize acids and maintain viscosity.

For the 2008 Tucson 6-cylinder model, Hyundai recommends using 5W-30 oil and changing it every 7,500 miles under normal driving conditions—but if you frequently drive in stop-and-go traffic, tow heavy loads, or operate in extreme temperatures, more frequent changes (every 3,000–5,000 miles) are wise.

By doing it yourself, you control the quality of oil and filter used, ensure proper installation, and avoid potential upselling at service centers. Plus, you’ll know exactly when and how your vehicle was serviced—giving you peace of mind on the road.

Tools and Materials You’ll Need

Before you begin, gather all necessary tools and supplies. Having everything ready beforehand saves time and prevents mid-process trips to the store.

Essential Tools

• Socket wrench set: A 17mm socket is typically needed for the drain plug.
• Oil filter wrench: Helps remove a tight or stuck oil filter. A strap-style or claw-type wrench works best.
• Funnel: Prevents spills when pouring new oil into the engine.
• Oil drain pan: Choose one with at least a 6-quart capacity to catch all the old oil.
• Jack and jack stands or ramps: The Tucson has decent ground clearance, but lifting the front end makes access easier and safer. Never rely solely on a jack—always use jack stands or drive onto ramps.
• Gloves and safety glasses: Protect your hands and eyes from hot oil and debris.
• Rags or paper towels: For wiping spills and cleaning the drain plug area.

Materials

• 5 quarts of 5W-30 motor oil: The 2008 Tucson 6-cylinder holds approximately 4.8 quarts with a filter change. Always buy one extra quart to top off if needed.
• New oil filter: Use a Hyundai OEM filter (part #26300-35503) or a high-quality aftermarket equivalent like Fram PH6607, Mobil 1 M1-108, or K&N HP-1008. Avoid cheap filters—they may not seal properly or could collapse under pressure.
• New drain plug washer: The crush washer on the drain plug should be replaced each time to prevent leaks. Hyundai uses a 14mm copper or aluminum washer (part #11233-23000).

Optional but Helpful

• Oil absorbent pads: Place under the work area to catch drips.
• Torque wrench: Ensures the drain plug is tightened to the correct specification (25–30 ft-lbs).
• Oil filter drain tool: Some filters come with a spout that directs oil into the pan—helpful for minimizing mess.
• Funnel with long spout: Makes pouring oil into the narrow filler neck easier.

Safety First: Preparing Your Vehicle

Safety is paramount when working under a vehicle. Follow these steps to create a safe working environment.

Park on Level Ground

Choose a flat, stable surface like a driveway or garage floor. Avoid slopes—even a slight incline can cause the vehicle to shift or roll.

Engage the Parking Brake

Pull the parking brake firmly to prevent the vehicle from moving. For extra security, place wheel chocks behind the rear tires.

Warm Up the Engine

Start the engine and let it run for 2–3 minutes. Warm oil flows more easily, allowing for a quicker and more complete drain. Do not let the engine get too hot—avoid touching exhaust components or the radiator cap.

Lift the Vehicle Safely

If using ramps:

• Drive the front wheels slowly onto the ramps until the vehicle is fully supported.
• Shift into Park (automatic) and engage the parking brake.
• Place wheel chocks behind the rear tires as a backup.

If using a jack and jack stands:

• Locate the front jack point—usually a reinforced section of the subframe just behind the front wheels.
• Raise the vehicle slowly and evenly.
• Place jack stands under the designated support points (check your owner’s manual for exact locations).
• Never work under a vehicle supported only by a hydraulic jack.

Allow Cooling Time (If Needed)

If the engine was recently running hot, wait 10–15 minutes before proceeding. Hot oil can cause burns, and components like the exhaust manifold may be dangerously hot.

Step-by-Step Oil Change Process

Now that your vehicle is safely positioned and prepared, it’s time to begin the oil change.

Step 1: Locate the Oil Drain Plug

Slide under the front of the vehicle and look for the oil pan—a flat, metal pan mounted to the bottom of the engine. The drain plug is a 17mm bolt on the lowest point of the pan. It’s usually centered or slightly toward the passenger side.

Step 2: Position the Drain Pan

Place the oil drain pan directly beneath the drain plug. Make sure it’s large enough to catch all the oil—about 5 quarts will drain out. Angle the pan slightly to avoid splashing.

Step 3: Remove the Drain Plug

Using a 17mm socket and ratchet, turn the drain plug counterclockwise. Hold the plug with your free hand as it loosens—oil will begin flowing immediately.

Pro Tip: Loosen the plug slowly at first to control the initial rush of oil. Once it’s free, remove it quickly and let the oil drain completely. This may take 10–15 minutes.

Step 4: Remove the Old Oil Filter

While the oil is draining, locate the oil filter. On the 2008 Tucson 6-cylinder, it’s mounted horizontally on the passenger side of the engine block, near the front.

Use an oil filter wrench to loosen the filter. Turn it counterclockwise. Be prepared—some oil will spill out when you remove it. Have a rag ready to catch drips.

Once loose, unscrew the filter by hand. Tip it downward into the drain pan to empty any remaining oil.

Step 5: Prepare the New Oil Filter

Before installing the new filter, take a moment to prepare it:

• Dip a clean finger in fresh oil and lightly coat the rubber gasket on the new filter.
• This helps create a better seal and prevents the gasket from tearing during installation.

Important: Do not over-grease the gasket—just a thin film is enough.

Step 6: Install the New Oil Filter

Screw the new filter onto the engine by hand. Turn it clockwise until the gasket makes contact with the mounting surface. Then, tighten it an additional ¾ turn (about 270 degrees). Do not overtighten—this can damage the gasket or make future removal difficult.

Step 7: Reinstall the Drain Plug

Once all the oil has drained, clean the drain plug and the surrounding area with a rag. Inspect the threads for damage.

Replace the old crush washer with a new one. This ensures a tight, leak-free seal.

Reinsert the drain plug and tighten it with a wrench. If you have a torque wrench, tighten to 25–30 ft-lbs. If not, snug it firmly—but don’t force it. Over-tightening can strip the threads in the oil pan.

Step 8: Add New Oil

Return to the top of the engine and locate the oil filler cap—usually on the valve cover, labeled “Oil” or marked with an oil can icon.

Remove the cap and insert a funnel. Slowly pour in 4.5 quarts of 5W-30 oil. Wait a minute for the oil to settle, then check the dipstick.

Add more oil in small increments until the level reaches the “Full” mark on the dipstick. Do not overfill—excess oil can cause foaming, reduced lubrication, and potential engine damage.

Replace the oil filler cap securely.

Step 9: Start the Engine and Check for Leaks

Start the engine and let it run for 30–60 seconds. This circulates oil and pressurizes the system.

Turn off the engine and wait 2–3 minutes for oil to settle. Then, check under the vehicle for leaks around the drain plug and oil filter. Also, recheck the dipstick to confirm the oil level.

If you see a leak:

• Turn off the engine immediately.
• Tighten the drain plug slightly or reinstall the filter if necessary.
• Wipe away any spilled oil to avoid confusion later.

Step 10: Reset the Oil Change Reminder Light

The 2008 Tucson has a maintenance reminder system that alerts you when an oil change is due. After completing the service, you’ll need to reset it.

To reset the “Change Oil” light:

1. Turn the ignition to the “ON” position (do not start the engine).
2. Press and hold the trip odometer button (located on the instrument cluster).
3. While holding the button, turn the ignition to “OFF,” then back to “ON.”
4. Continue holding the button until the oil change light blinks and then turns off (usually takes 10–15 seconds).
5. Release the button. The reminder is now reset.

Troubleshooting Common Issues

Even with careful preparation, problems can arise. Here’s how to handle common issues:

Drain Plug Won’t Come Loose

If the drain plug is stuck:

• Apply penetrating oil (like WD-40 or PB Blaster) and let it sit for 10–15 minutes.
• Use a longer wrench or a breaker bar for extra leverage.
• Tap the wrench gently with a hammer to break corrosion loose.
• Never use excessive force—stripped threads require costly repairs.

Oil Filter is Too Tight

If the old filter won’t budge:

• Use a dedicated oil filter wrench with better grip.
• Cut the old filter with a filter cutter (if accessible).
• As a last resort, drive a screwdriver through the filter canister for leverage—but be careful not to damage the engine block.

Oil Leak After Installation

If you notice a leak:

• Check that the drain plug is tight and the washer is new.
• Ensure the oil filter is properly seated and not cross-threaded.
• Verify the oil filler cap is secure.
• Clean the area and monitor for 24 hours—sometimes minor seepage stops once the gasket seats fully.

Overfilled or Underfilled Oil

• If overfilled, drain excess oil using a fluid extractor or by removing the drain plug slightly.
• If underfilled, add oil slowly and recheck the dipstick.
• Always wait a few minutes after turning off the engine for an accurate reading.

Proper Disposal of Used Oil and Filter

Used motor oil is toxic and harmful to the environment. Never pour it down a drain, on the ground, or into the trash.

Drain the Oil Filter

Before disposal, puncture the old filter and let it drain for 24 hours over a drip pan. This removes residual oil and makes recycling more efficient.

Recycle Responsibly

Take used oil and filters to:

• Auto parts stores (e.g., AutoZone, O’Reilly, Advance Auto Parts)—most offer free recycling.
• Local recycling centers or hazardous waste facilities.
• Service stations that accept used oil.

Many retailers will take up to 5 gallons of used oil per visit. Store oil in a clean, leak-proof container with a secure lid—milk jugs or dedicated oil bottles work well.

Final Tips for Success

• Keep a maintenance log: Record the date, mileage, oil type, and filter brand used. This helps track service intervals and adds value if you sell the vehicle.
• Use quality parts: Cheap oil or filters may save money upfront but can lead to engine problems down the road.
• Check other fluids: While under the vehicle, inspect coolant, brake fluid, and transmission fluid levels.
• Inspect belts and hoses: Look for cracks, fraying, or leaks—especially on the serpentine belt and radiator hoses.
• Don’t rush: Take your time. A careful, methodical approach prevents mistakes and ensures a job well done.
