The engine in the 1997 Toyota Supra 3.0L is a naturally aspirated inline-six that has earned a legendary reputation for durability. When performing maintenance, it is crucial to select a viscosity that meets the manufacturer’s specifications for the operating climate. For the 2JZ-GE engine, SAE 5W-30 is the preferred viscosity. The total oil capacity is 5.5 quarts when including the filter replacement. After refilling, the oil level must be checked to ensure proper lubrication coverage. The oil drain plug torque specification is 27 ft/lbs, a critical detail for preventing leaks or stripped threads on the aluminum pan.
Selecting the right filter is just as vital as the oil itself. The AMSOIL Oil Filter, part number EA15K51-EA, is engineered to match or exceed the capacity of the original equipment manufacturer filters while offering a higher level of filtration. By capturing smaller wear-causing contaminants, this filter helps extend the life of the engine’s moving parts. For owners who prefer a widely available alternative, the WIX Oil Filter, part number 51348-EA, is also a recommended option for this application. Both filters ensure that the oil remains clean throughout its service interval, which is a key factor in maximizing the engine’s potential lifespan.
Transmission and Cooling System Fluids
The 1997 Toyota Supra comes in different transmission configurations, and each requires specific attention regarding fluid capacity and type. For vehicles equipped with the automatic transmission, specifically the A340E, the total fill capacity is 7.6 quarts, while the initial fill requires 1.7 quarts. The manual transmission, which often features the W58 5-speed gearbox, has a capacity of 5.5 pints. Using the correct fluid ensures smooth shifting and prevents premature wear in the gear train.
For automatic transmission duty, AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid is highly recommended. This fluid is designed to withstand heavy towing, elevated temperatures, and challenging terrain while remaining fluid in sub-zero conditions. It provides reserve protection during heavy use, which is beneficial for the Supra’s performance applications. Alternatively, the AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid offers excellent cold-weather performance and resistance to harmful sludge, ensuring smooth, shudder-free shifts.
Manual transmission service requires a high-quality gear lube that meets GL-5 specifications. The AMSOIL SEVERE GEAR® 75W-90 100% Synthetic Gear Lube is an ideal choice for this application. It contains friction modifiers suitable for limited-slip applications and helps control thermal runaway. For those requiring an extended service interval or operating in extreme cold, the AMSOIL SEVERE GEAR® 75W-110 100% Synthetic Gear Lube provides advanced protection against wear and corrosion. Both options are effective in reducing operating temperatures and extending the life of the gear seals.
Proper cooling system maintenance is critical for any high-performance engine. The 1997 Supra’s cooling system capacity varies slightly depending on the transmission type, with the automatic transmission model requiring 9 quarts and the manual transmission model requiring 7.9 quarts. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a unique poly-organic acid (OAT) formulation that is safe for a wide variety of vehicles. It offers protection for up to 150,000 miles or five years, whichever comes first. This product is ethylene glycol-based and is compatible with all other antifreeze and coolant colors. For those who prefer a concentrated formula that can be mixed with distilled water for ultimate control over freeze points, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant is an excellent alternative, offering extended protection in both passenger and heavy-duty applications.
Brake Fluid and Differential Care
Safety is paramount when maintaining a vehicle of this caliber. The hydraulic brake fluid system in the 1997 Toyota Supra should be serviced with a fluid that provides consistent performance under varying conditions. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is designed to ensure excellent ABS and traction-control responsiveness. It provides a stable viscosity over a wide temperature range, which is essential for maintaining braking precision. This synthetic fluid resists boiling and moisture absorption better than conventional fluids, ensuring reliable stopping power.
The rear differential of the Supra also requires specific care, particularly regarding capacity and lubricant type. The rear standard differential, rated for GL-5 above -18°C, has a capacity of 2.7 pints. For temperatures below -18°C, a slightly different specification may be preferred, such as 80W-90 or 80. The AMSOIL SEVERE GEAR® 80W-90 100% Synthetic Gear Lube is an excellent choice for these standard differentials. It offers advanced protection against wear and rust while helping to reduce operating temperatures. For limited-slip differentials, it is important to fill with oil designated for use in limited-slip applications. The SEVERE GEAR® 75W-90 and 75W-110 grades also contain friction modifiers that are beneficial for limited-slip setups, ensuring that the differential operates quietly and efficiently.
