DIY Oil Change for Your Toyota GR Supra (A90)

Owning a high-performance machine like the Toyota GR Supra (A90 generation, 2020 onwards) is a thrilling experience, and keeping it in prime condition is paramount. While taking your Supra to a specialist for every service is an option, performing routine tasks like an oil change yourself can be incredibly rewarding, cost-effective, and provide a deeper understanding of your vehicle. This guide will walk you through the entire process, specifically tailored for the 3.0L engine found in these modern marvels, ensuring you have all the knowledge to tackle this essential maintenance task with confidence.

Changing the engine oil is one of the most fundamental aspects of vehicle upkeep. It ensures that your engine's moving parts remain properly lubricated, reducing wear and tear, dissipating heat, and keeping contaminants at bay. For a vehicle designed for performance, such as the GR Supra, maintaining fresh, clean oil is even more critical. Thankfully, despite its sophisticated engineering, the oil change procedure on the A90 Supra is surprisingly straightforward, arguably simpler than many other cars, especially with the easily accessible oil filter housing.

Understanding Your Supra's Oil System

Before diving into the practical steps, it's beneficial to understand a couple of unique aspects of the GR Supra's oil system, which is largely derived from BMW. The most notable difference for many DIY enthusiasts will be the absence of a traditional dipstick. Instead, the oil level is monitored digitally via the car's infotainment system or dash display. While this might seem futuristic, it does mean a slight adjustment to the usual post-oil change routine.

Secondly, the oil filter is housed in a cartridge, accessible from the top of the engine bay, rather than the more common spin-on canister found on many other vehicles. This design makes filter replacement incredibly clean and easy, a definite plus for the home mechanic. The engine also has a specific under-tray panel designed for easy access to the drain plug, avoiding the need to remove the entire underbody protection.

Essential Tools and Parts for the Job

Having the right equipment before you start is key to a smooth and efficient oil change. Here's a comprehensive list of what you'll need:

Required Tools:

• 17mm Socket and Ratchet: For the engine oil pan drain plug.
• 32mm Socket and Ratchet: Specifically for the oil filter cap.
• Torque Wrench: Crucial for ensuring the drain plug is tightened to the correct specification (25 Newton-metres).
• Drain Pan: Ensure it has a capacity of at least 7.0 quarts (approximately 7 litres) to safely collect all the old oil.
• Vehicle Lifting Equipment: Drive-on ramps or a jack and sturdy jack stands are essential for safely raising the front end of the car. Never work under a car supported only by a jack.
• Funnel: To prevent spills when adding new oil.
• Shop Rags or Towels: For cleaning up any drips or spills.
• Gloves: To keep your hands clean and protected.

Required Parts:

• Engine Oil: You'll need approximately 6.9 quarts (about 6.5 litres) of fresh engine oil. The manufacturer's recommended oil is generally 0W-20. However, if you plan on track driving or spirited performance, some owners opt for 5W-30 for enhanced protection under high-stress conditions. Always refer to your owner's manual for the most up-to-date specifications.
• Engine Oil Filter: A new filter is vital. Popular choices include the Wix WL10342 or equivalent parts from reputable manufacturers like Mahle, Mann-Filter, or OEM Toyota/BMW. Ensure it comes with new O-rings for the filter cap.

It's always a good idea to purchase a little extra oil beyond the stated capacity, just in case you need to top up or for future use, although the Supra's digital check system should guide you precisely.

Step-by-Step Oil Change Procedure (2020+ Toyota GR Supra 3.0L)

Follow these steps carefully to ensure a successful and safe oil change:

Step 1: Prepare the Vehicle and Workspace

Begin by running the engine for a few minutes until it reaches its normal operating temperature. Warm oil flows more easily, ensuring a more complete drain. Once warm, park the car on a flat, level surface.

Step 2: Raise the Vehicle Safely

Use your chosen method (drive-on ramps or jack and jack stands) to safely raise the front end of the Supra. Ensure the vehicle is stable and secure before proceeding. Always double-check your setup.

Step 3: Access the Drain Plug

Pop the bonnet and remove the engine oil fill cap. This helps to prevent a vacuum from forming and allows the oil to drain more freely. Now, locate the engine oil drain access panel on the under-tray beneath the car. This is a dedicated panel that you simply twist counter-clockwise and pull out to reveal the drain plug. This ingenious design saves significant time compared to removing the entire under-tray.

Step 4: Drain the Old Oil

Position your drain pan directly underneath the drain plug. Using your 17mm socket and ratchet, carefully loosen and remove the drain plug. Be prepared for the oil to come flowing out quickly. Allow sufficient time for the oil to drain completely; this can take 10-15 minutes. While the oil is draining, you can move on to replacing the filter.

Step 5: Replace the Oil Filter

With the old oil draining, focus on the engine bay. Remove the top engine cover (it usually just lifts off). Locate the engine oil filter cap on the driver's side of the engine bay. It's a black plastic cap. Using your 32mm socket and ratchet, carefully unscrew the oil filter cap. As you lift it out, the old filter element should come with it. If not, gently pull the old filter out from the housing.

Once the old filter is removed, take off the large O-ring from the filter cap and replace it with a new one supplied with your new filter. There might also be one or two smaller O-rings on the filter itself or the cap's stem; replace these too. Lubricate all new O-rings with a thin film of fresh engine oil to ensure a good seal and prevent pinching. Seat the new oil filter element firmly into the filter cap. Reinstall the filter cap and new filter into the housing, tightening it by hand first, then with your 32mm socket until snug. Do not overtighten, but ensure it's secure.

Step 6: Reinstall Drain Plug and Fill with New Oil

Once the old oil has fully drained, clean the area around the drain plug opening. Reinstall the drain plug, ensuring it's properly seated. Crucially, use your torque wrench to tighten the drain plug to 25 Newton-metres (Nm). This prevents both leaks and damage from overtightening. Reinstall the under-tray access panel by twisting it clockwise until secure.

Back in the engine bay, use your funnel to carefully add the new engine oil (approximately 6.5-6.9 litres). Pour slowly to avoid air pockets and spills. Once filled, reinstall the engine oil fill cap and the top engine cover.

Step 7: Final Checks and Oil Level Verification

Lower the front end of the vehicle from the ramps or jack stands, ensuring it's on a level surface. Start the engine and let it run for a few minutes, allowing the new oil to circulate and the engine to warm up to operating temperature. This is crucial for the digital oil level check.

Turn off the engine. Now for the unique part: checking the oil level. Navigate through your Supra's infotainment system (usually under 'Car' -> 'Vehicle Status' -> 'Engine Oil Level') to initiate the digital oil level check. The car will take a few moments to perform the measurement. It will then display whether the oil level is correct. If it indicates it's low, add a small amount of oil (e.g., 250ml) at a time and re-check until the display shows the correct level.

Step 8: Reset Oil Change Interval Warning

The final step is to reset the service reminder. With the ignition on (engine off), press the engine start/stop button three times in quick succession. This should bring up a diagnostic menu on the instrument cluster. Scroll through the options until you find the 'Oil Change Interval Reset' or similar, and follow the on-screen prompts to reset it. This will clear the service warning and prepare your Supra for its next maintenance cycle.
