2025 Chevy Traverse Oil Change: Specifications, Capacity, and DIY Service Guide

Performing an oil change on a 2025 Chevy Traverse requires 6.0 quarts (5.7 liters) of SAE 0W-20 full synthetic oil meeting GM's dexos1 Gen 3 specification, paired with an ACDelco PF66 oil filter. Service is recommended every 7,500 miles or when the GM Oil Life System indicates remaining life is low.

Understanding the 2025 Chevy Traverse Engine and Oil Requirements

The redesign of the Chevrolet Traverse introduced a major powertrain update: replacing the long-standing 3.6-liter naturally aspirated V6 with a high-output 2.5-liter turbocharged inline-4 engine (LK0). Generating 328 horsepower and 326 lb-ft of torque, this forced-induction powertrain operates under higher internal cylinder pressures and thermal stress than its predecessor. As a result, selecting the correct engine oil is critical to long-term engine durability.

Why dexos1 Gen 3 Specification Matters

General Motors strictly specifies dexos1 Gen 3 full synthetic oil for the 2.5L turbo engine. This specification is designed to address technical challenges unique to modern turbocharged, direct-injected engines:

• Low-Speed Pre-Ignition (LSPI) Protection: LSPI is an uncontrolled combustion event that occurs at low speeds under heavy engine loads. It can cause severe piston ring-land breakage and catastrophic engine failure. Dexos1 Gen 3 oils use advanced detergent additives (minimizing calcium while increasing magnesium) to neutralize LSPI risks.
• Turbocharger Deposit Control: Turbochargers operate at extreme temperatures. Non-approved oils can oxidize rapidly, leaving carbon deposits ("coking") inside the turbocharger oil lines and bearings, leading to premature turbo failure.
• Timing Chain Wear Resistance: Direct-injection engines produce soot particles that enter the oil sump. Dexos1 Gen 3 oil contains dispersants that keep soot suspended, preventing abrasive wear on the timing chain and variable valve timing (VVT) actuators.

Using conventional engine oil, blend formulations, or synthetic oils that lack the official dexos1 Gen 3 logo can compromise engine life and potentially invalidate portions of GM's 5-year/60,000-mile powertrain warranty.

Tools, Parts, and Supplies Needed for DIY Maintenance

Gathering the correct equipment beforehand guarantees a smooth oil change process without unnecessary delays.

Required Parts & Fluids

1. 6 Quarts of 0W-20 dexos1 Gen 3 Engine Oil: Look for approved brands displaying the official green dexos icon on the front label, such as Mobil 1 Extended Performance, Pennzoil Platinum, Valvoline Advanced Full Synthetic, or ACDelco dexos1 Gen 3.
2. ACDelco PF66 Oil Filter: Standard spin-on filter housing designed for GM's modern four-cylinder engines. Ensure the rubber O-ring seal is included on the filter rim.
3. New Drain Plug Washer: GM uses an integrated rubber seal on the 15mm drain plug bolt. Inspect this seal; replace the washer or the entire plug if the rubber is cracked, flattened, or brittle.

Required Tools & Equipment

• Drive Ramps or Hydraulic Floor Jack with Jack Stands: Rated for medium-to-large crossover SUVs (minimum 3-ton rating recommended).
• Wheel Chocks: For safety on rear wheels when elevating the front end.
• 15mm Box Wrench or Socket with Ratchet: For removing the drain plug.
• Torque Wrench (3/8-inch drive): Capable of measuring 18 lb-ft accurately.
• 73mm 14-Flute Oil Filter Cap Wrench or Strap Wrench: Fits the end of the ACDelco PF66 filter.
• Oil Catch Drain Pan: Minimum 8-quart capacity to prevent overflow.
• Wide-Mouth Oil Funnel: Clean and dedicated to engine oil.
• Safety Equipment: Safety glasses, nitrile gloves, shop rags, and cardboard/tarp to catch stray drips.

Step-by-Step DIY Oil Change Procedure

Follow these detailed steps to drain, replace, and refill the engine oil safely on your 2025 Chevy Traverse.

Step 1: Vehicle Warm-up and Setup

1. Warm the Engine: Park the vehicle on a flat surface and run the engine for 3 to 5 minutes. Warm oil drains faster and holds suspended contaminants in liquid form better than cold oil. Turn off the ignition and set the electronic parking brake.
2. Elevate the Front: Drive the front wheels up onto sturdy ramps, or lift the front of the SUV with a floor jack and support it securely on jack stands positioned on approved frame points.
3. Secure the Rear: Place wheel chocks securely behind both rear tires to prevent rolling.
4. Pop the Hood: Open the hood and remove the engine oil filler cap (marked "0W-20 dexos"). This releases vacuum pressure and allows oil to drain rapidly from the sump.

Step 2: Draining the Used Engine Oil

1. Position Safety Gear and Drain Pan: Put on eye protection and nitrile gloves. Place your catch pan beneath the engine oil drain plug, positioned slightly toward the rear to account for the angle of the oil stream.
2. Remove the Drain Plug: Using a 15mm socket or wrench, loosen the oil pan drain plug counterclockwise. Carefully unscrew the plug by hand for the last few threads, keeping inward pressure until it clears, then quickly pull it away to avoid hot oil splashing your hands.
3. Allow Full Drainage: Let the oil drain completely into the pan for 10 to 15 minutes until it slows to an occasional drip.
4. Inspect the Drain Plug: Clean the drain plug threads with a shop rag. Inspect the integrated rubber sealing gasket. If damaged, replace it before reinstalling.
5. Reinstall and Torque: Thread the drain plug back into the oil pan by hand to prevent cross-threading. Tighten with your 15mm socket and finish with a torque wrench set to 18 lb-ft (25 N·m). Do not overtighten, as aluminum oil pan threads can strip easily.

Step 3: Replacing the Oil Filter

1. Locate the Filter: The ACDelco PF66 filter is positioned on the lower block area facing downward or slightly angled. Position the drain pan directly underneath it.
2. Remove the Old Filter: Use an oil filter socket wrench or band wrench to turn the filter counterclockwise. Once loose, unscrew it by hand. Turn the filter upright as it detaches to minimize oil spilling down the side of the engine block.
3. Check the Sealing Surface: Look closely at the mounting pad on the engine block to ensure the old rubber gasket did not stick to it. If the old gasket remains on the engine, remove it immediately. "Double-gasket" installations lead to severe oil blowout and total oil loss within seconds of starting the vehicle.
4. Prep the New Filter: Wipe the engine filter mating surface clean with a rag. Take your new ACDelco PF66 filter and apply a light coat of clean 0W-20 oil around its top rubber O-ring gasket. Optional: Pour about 2 to 3 ounces of fresh oil directly into the filter to assist quick oil pressure build on initial start.
5. Install the New Filter: Spin the new filter on by hand clockwise until the rubber gasket makes firm contact with the engine block mounting surface. From that point, turn the filter an additional 3/4 to 1 full turn by hand (or torque to 18 lb-ft if using an adapter tool). Do not over-torque with heavy tools.

Step 4: Refilling with Fresh Engine Oil

1. Insert Funnel: Place a clean funnel into the oil fill neck on top of the engine valve cover.
2. Add Oil: Pour in 5.5 quarts of certified 0W-20 dexos1 Gen 3 full synthetic oil first. Stop and let the oil settle in the oil pan for 2 minutes.
3. Check Dipstick Initial Level: Pull out the dipstick, wipe it clean on a rag, reinsert it fully, and pull it back out to read the level.
4. Top Off: Add the remaining half-quart to reach the full 6.0-quart capacity, bringing the fluid level right to the top of the crosshatched "Full" zone on the dipstick.
5. Reinstall Cap: Put the oil fill cap back on securely and tighten it until it clicks or seats firmly.

Step 5: Startup, Leak Check, and Verification

1. Start Engine: Start the engine while monitoring the instrument cluster. The low oil pressure light should extinguish within 2 to 3 seconds. Let the engine idle for 2 minutes—do not rev the motor.
2. Inspect for Leaks: Look underneath the vehicle while the engine is running. Inspect around the drain plug and the base of the oil filter for drips or seepage.
3. Lower Vehicle: Turn off the ignition. Remove jack stands and lower the Traverse back to flat ground (or back down off the ramps).
4. Final Dipstick Level Check: With the vehicle parked on a flat surface, let it sit for 5 minutes for the oil to drain back into the pan. Pull the dipstick, clean it, reinsert completely, and pull it out. Verify that the oil level is precisely at the upper dot/crosshatch area. Add a small fraction of a quart if needed, but do not overfill.

How to Reset the GM Oil Life System (IOLM) on the 2025 Traverse

The 2025 Chevy Traverse uses an Intelligent Oil Life Monitor (IOLM) algorithm that calculates oil degradation based on engine RPM, operating temperatures, mileage, short trips vs. highway driving, and towing loads. After an oil change, the system must be reset to 100%.

Resetting via Driver Information Center (Steering Wheel Controls)

1. Turn the vehicle ignition to ON/RUN mode without starting the engine (press and hold the Engine Start/Stop button for 5 seconds without depressing the brake pedal).
2. Use the right-hand steering wheel keypad controls (scroll wheel/arrows) to navigate the Driver Information Center (DIC) on the digital cluster screen.
3. Scroll to the Info tab (represented by an "i" icon or vehicle status page).
4. Scroll down until Oil Life is displayed on the screen (showing current percentage).
5. Press and hold the thumbwheel (or the OK button) on the steering wheel for several seconds until the percentage changes to 100%. An audible chime will confirm the reset.
6. Turn the ignition off.

Resetting via Touchscreen Infotainment (17.7-inch Display)

On certain trims, the Oil Life menu is also accessible via the main display:

1. Turn the ignition to ON/RUN mode.
2. On the main center touchscreen, tap Vehicle Status or Settings.
3. Select Vehicle Maintenance -> Oil Life.
4. Touch and hold the Reset button on the touchscreen until the display indicates 100% Oil Life remaining.

Maintenance Schedules, Driving Conditions, and Warranty Protection

Following the appropriate service intervals preserves engine longevity and protects warranty coverage.

Standard vs. Severe Service Intervals

GM recommends changing your engine oil based on the following usage patterns:

• Normal Driving Conditions: Change oil every 7,500 miles (12,000 km) or 12 months, whichever comes first, or when alerted by the Oil Life System. Normal driving includes regular highway cruises, light suburban commuting, and steady speeds in mild climates.
• Severe Driving Conditions: Change oil every 3,000 to 5,000 miles (5,000 to 8,000 km) or 6 months. Severe conditions include:
  • Frequent short trips under 5 miles (preventing full engine warm-up).
  • Driving in extreme hot (over 90°F / 32°C) or freezing temperatures.
  • Extensive engine idling (such as taxi, delivery, or commercial stop-and-go driving).
  • Frequent towing of trailers, campers, or boats.
  • Operation on dusty, gravel, or unpaved off-road paths.

Protecting Your Warranty

Under federal laws such as the Magnuson-Moss Warranty Act, vehicle owners have the right to perform their own maintenance or use independent repair shops without voiding their factory warranty, provided the correct fluids and filters are used.

To safeguard your GM 5-year/60,000-mile powertrain warranty when performing DIY oil changes:

1. Save All Receipts: Keep physical or digital copies of receipts for every bottle of dexos1 Gen 3 oil and ACDelco PF66 filter purchased.
2. Log Every Service: Record the date, mileage, oil brand, viscosity, filter part number, and reset status in a notebook or digital vehicle log.
3. Never Exceed 10,000 Miles or 1 Year: Regardless of what the Oil Life System shows, GM mandates that oil must be changed at least once every 12 months.

Frequently Asked Questions

Can I use 5W-30 oil instead of 0W-20 in my 2025 Chevy Traverse?

No. General Motors specifically engineered the 2.5L Turbo LK0 engine for SAE 0W-20 viscosity oil. Using thicker oils like 5W-30 increases internal oil flow resistance, causes slow variable valve timing (VVT) actuator responses, lowers fuel economy, and may cause oil starvation to critical turbocharger bearings during cold starts. Only use 0W-20 oil bearing the dexos1 Gen 3 certification.

How often should I check the engine oil level manually?

You should check the oil level manually on the dipstick at least once every month or before embarking on long road trips. Turbocharged direct-injected engines naturally consume a minor amount of oil during operation. Relying solely on the Oil Life System or electronic low-level warnings can result in operating with low oil volume between service intervals.

What is the exact part number for the oil filter on a 2025 Traverse?

The factory original equipment oil filter for the 2025 Chevy Traverse (2.5L Turbo) is the ACDelco PF66 (GM Part # 12693541 or 12707246). If using premium aftermarket brands, cross-reference to ensure exact fitment, such as Mobil 1 M1-114A, Wix 57041, or STP Extended Life S12060.

What happens if I use non-dexos certified oil?

Using non-certified oil risks severe engine damage from low-speed pre-ignition (LSPI), sludge buildup, and thermal breakdown inside the turbocharger. Additionally, if an engine failure occurs and fluid analysis reveals non-compliant oil was used, GM may deny warranty coverage for the repair.

Does the 2025 Chevy Traverse require a special drain plug washer?

The 2025 Traverse 15mm drain plug features an integrated captive rubber seal on the underside of the bolt head rather than a separate crush washer. Inspect the rubber bead during each oil change. If the rubber seal is cracked, squished, or leaking, replace the entire drain plug assembly (GM Part # 11562588 or equivalent standard GM drain plug).

Final Recommendations for Owners

To keep your 2025 Chevy Traverse running smoothly, make oil maintenance a high priority. The 2.5L turbocharged engine delivers impressive output, but its longevity depends directly on clean, high-specification lubricant.

• Take advantage of your complimentary initial service visit at an authorized Chevrolet dealership within your first year of vehicle ownership.
• For subsequent services, whether done at home or through an independent mechanic, insist on using ACDelco PF66 filters and 0W-20 dexos1 Gen 3 full synthetic oil.
• Check your dipstick monthly and never allow the engine oil level to drop below the minimum indicator mark.
• Always reset the GM Oil Life System immediately after changing the oil to maintain accurate maintenance tracking.
