Engine Oil and Filtration Requirements
For the 2.0L engine in the 2022 GR Supra, the manufacturer specifies a viscosity of 0W-20 for all temperature ranges. The oil pan capacity is 5.5 quarts when the oil filter is replaced. It is critical to torque the drain plug to 18 ft/lbs and replace the drain plug gasket every time the oil is changed to prevent leaks. While AMSOIL does not currently list a specific oil filter for this engine configuration in the fitment data, the oil itself is the primary component for protecting the engine internals.
The AMSOIL 0W-20 LS motor oil is formulated to meet the precise requirements of this turbocharged four-cylinder engine. The LS formula features a precise blend of synthetic base oils and premium additives that are particularly beneficial for gasoline, diesel, and hybrid European vehicles. This formulation ensures that the oil remains fluid enough to reach all critical components during cold starts, yet viscous enough to protect the turbocharger bearings and piston rings under high load. By extending the life of the oil, you are also reducing the frequency of maintenance, which is a distinct advantage for owners who want to keep their Supra on the road rather than in the shop.
When performing an oil change, it is important to verify the oil level after refill using the dipstick or electronic monitoring system, ensuring the engine is not overfilled or underfilled. The 0W-20 grade is essential for the efficient operation of the variable valve timing and the cooling of the turbocharger, which relies on a steady flow of oil for heat dissipation.
Transmission and Cooling System Fluids
The 2022 Toyota GR Supra is equipped with an 8HP51 automatic transmission, which requires a specific fluid to handle the shifting loads and thermal output generated by the turbocharged engine. The total fill capacity for the automatic transmission is 9.6 quarts. The AMSOIL Signature Series Fuel-Efficient Automatic Transmission Fluid is designed to meet or exceed the requirements for this 8-speed automatic unit. It remains fluid in sub-zero temperatures, providing immediate protection and reserve capacity during heavy use or abuse.
The cooling system is another critical area where synthetic fluids outperform conventional standards. The 2.0L Supra requires either the Passenger Car & Light Truck Antifreeze & Coolant or the Propylene Glycol version depending on whether a pre-mix or concentrate is preferred. The coolant capacity varies slightly based on the system configuration, ranging from 4.2 quarts with the LTCC4 system to 10.5 quarts with the HTCC system. Using a high-quality antifreeze is essential to prevent corrosion in the aluminum engine block and to manage the high operating temperatures typical of performance driving. The AMSOIL formulations are phosphate, nitrate, nitrite, silicate, borate, and amine-free, making them compatible with all other antifreeze colors and safe for the various metals used in modern cooling systems.
Braking performance is paramount in a sports car like the GR Supra. The vehicle recommends the use of DOT 4 Low Viscosity brake fluid. AMSOIL’s Synthetic Brake Fluid provides a stable viscosity across a wide temperature range, which is crucial for maintaining consistent brake pedal feel. This fluid reduces the risk of fade during track days or aggressive canyon driving, ensuring that the braking system responds instantly to driver input.
Fuel system health is also a consideration for the GDI (Gasoline Direct Injection) engine. The 2.0L engine benefits significantly from the use of AMSOIL P.i. Performance Improver. This additive helps restore up to 14% horsepower by cleaning the fuel injectors and restoring them to 100% flow rate. It also helps control pre-ignition knock, a common concern in direct injection engines, and improves fuel economy. Regular use of this additive can help prevent carbon buildup, a known issue in GDI engines that can affect performance and emissions over time.
About the Vehicle
The 2022 Toyota GR Supra 2.0L is the lighter, more agile sibling to its 6-cylinder counterpart, offering a driving experience that emphasizes agility and directness. The “GR” designation stands for Gazoo Racing, Toyota’s motorsports division, indicating that this vehicle was developed with a focus on driver engagement. The 2.0-liter B48 engine, sourced from BMW but tuned by Toyota, delivers a punchy power delivery that rewards a driver who knows how to use the revs. The vehicle features a near 50/50 weight distribution, which is ideal for neutral handling and sharp cornering.
Owners of the GR Supra often praise its steering feel and chassis balance, noting that it behaves more like a traditional sports car than many modern performance vehicles. The 2.0L model is slightly lighter than the 6-cylinder version, which enhances its cornering capabilities. It is a rear-wheel-drive coupe that offers a compelling alternative to European rivals, combining Japanese reliability with European-inspired dynamics. The interior, while functional, focuses on the driver, with a cockpit layout that keeps all controls within reach.
Despite its reputation for reliability, there are a few issues that owners of the GR Supra, particularly those with the 2.0L turbo engine, should be aware of. One common concern is the potential for carbon buildup on the intake valves due to the direct injection system. This can lead to reduced performance and rough idling over time. Using a high-quality fuel system cleaner like AMSOIL P.i. regularly can help mitigate this issue by keeping the injectors clean and reducing carbon deposits.
Another area of attention for the GR Supra is the transmission software and fluid health. Some owners have reported shift shudder or hesitation, particularly in colder weather or with high mileage. While software updates from Toyota can address some of these issues, using a premium synthetic transmission fluid that maintains its viscosity and lubricity at high temperatures can provide a smoother shift experience and extend the life of the clutch packs inside the transmission.
Thermal management is also a key area for the 2.0L model. The turbocharger generates significant heat, and the cooling system is under constant pressure to keep the engine at optimal operating temperatures. Overheating can lead to premature wear of the head gasket or warping of the cylinder head. Ensuring that the coolant is fresh and capable of handling high boiling points is essential for preventing thermal stress. Additionally, the turbocharger bearings rely heavily on the quality of the engine oil; using an oil that breaks down under heat can lead to turbo failure.
Finally, brake fade can be a concern for owners who push the vehicle on track or drive aggressively. The standard brake fluid is hygroscopic, meaning it absorbs moisture over time, which lowers its boiling point. Regular flushing with a high-temperature synthetic brake fluid can prevent this moisture accumulation, ensuring that the braking system remains effective even after repeated hard stops.
