Maintaining the lubrication system of your 2001 Acura NSX begins with the engine oil, which is the lifeblood of your V-6 powerplant. For this vehicle, the manufacturer specifies SAE 10W-30 for temperatures above -20°C, while 5W-30 is the preferred grade when temperatures drop below 0°C. The engine oil capacity is 5.3 quarts when a filter change is included. When performing this service, it is critical to torque the oil drain plug to exactly 33 ft/lbs and always install a new washer on the drain bolt to prevent leaks. Choosing the right AMSOIL Signature Series Motor Oil ensures that your engine receives superior protection against horsepower loss and wear, even under the most demanding conditions. For those seeking extended intervals, the Extended-Life version provides up to 20,000 miles of protection, while the OE formula offers a robust defense against sludge without the premium price tag. If your NSX has surpassed the 75,000-mile mark, the High-Mileage formula is specifically engineered with boosted detergents to reduce sludge by 67% and improve engine cleanliness.
Proper filtration is just as vital as the oil itself. The recommended WIX Oil Filter features premium media that exceeds the performance of standard OEM-branded filters. This component is essential for trapping contaminants and protecting the delicate components of the C30A1 engine. Replacing the oil filter every time you change the oil ensures that the newly added synthetic fluid remains clean, maximizing the benefits of the lubricant’s advanced additive packages. By using a high-quality filter in conjunction with AMSOIL synthetic motor oil, you ensure that your engine runs cleaner and lasts longer, preserving the power delivery that Acura enthusiasts value.
Transmission and Cooling System Requirements
The 2001 NSX presents a unique requirement for transmission fluids depending on whether the vehicle is equipped with an automatic or a manual gearbox. For the automatic transmission, the total fill capacity is 7.4 quarts, though an initial fill requires only 3.1 quarts. The AMSOIL Signature Series Multi-Vehicle Automatic Transmission Fluid is an ideal choice here, offering exceptional resistance to the heat and stress that an automatic transmission faces during spirited driving. It remains fluid in extreme cold and provides reserve protection during heavy use. The OE Multi-Vehicle version is a comparable alternative that resists sludge and promotes smooth, shudder-free shifts, making it a reliable choice for everyday driving.
If your NSX is equipped with the 6-speed manual transmission, the fluid requirements are equally specific. The capacity for the manual gearbox is 5.7 pints. For this application, AMSOIL 5W-30 Manual Synchromesh Transmission Fluid is the recommended fluid. It is formulated to reduce friction, heat, and wear while resisting oxidation and acid buildup. This fluid maximizes fuel economy and ensures improved cold weather shifting, which is crucial for the precise gear engagement expected from a manual sports car. Using the wrong fluid can lead to difficult shifting or premature wear of the synchromesh rings, which are critical for the smooth operation of the transmission.
Cooling system maintenance is another area where precision matters. The 2001 Acura NSX requires a specific amount of coolant depending on the radiator configuration. Models with the MTXL16 radiator require 16.9 quarts, while those with the ATXL1 radiator require 12.7 quarts. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a pre-mixed 50/50 solution that protects all cooling system metals, gaskets, and hoses. It is phosphate-, nitrate-, and silicate-free, making it compatible with a wide variety of engine materials. For those who prefer a concentrated formula, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers extended service intervals of up to 150,000 miles or 5 years and is safe for the environment. Both options provide superior corrosion protection compared to conventional coolants, ensuring your engine stays at optimal operating temperatures.
AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid and Essential Maintenance
Brake safety cannot be overlooked on a high-performance vehicle like the NSX. The recommended brake fluid is a DOT 3 or DOT 4 fluid, specifically the Acura Heavy Duty Brake Fluid. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid meets these requirements and offers excellent ABS and traction-control responsiveness. Synthetic brake fluids provide a stable viscosity over a wide temperature range, ensuring that your braking system remains consistent whether you are on a hot track day or a cold morning commute. Unlike conventional fluids, synthetic options absorb less moisture over time, which helps prevent boiling and maintains a firm pedal feel.
For vehicle owners who plan to store their NSX seasonally, or for those looking to maximize engine performance through routine maintenance, additional AMSOIL products can be highly beneficial. The AMSOIL P.i. Performance Improver is a powerful gasoline additive that restores up to 14% horsepower and cleans fuel injectors to 100% flow rate after just one tank of fuel. This helps prevent carbon buildup and controls pre-ignition knock, ensuring that your engine performs at its peak. If your vehicle will be sitting for an extended period, the AMSOIL Engine Fogging Oil is designed to protect internal components from rust and corrosion. For those who want to keep their vehicle looking pristine, the AMSOIL Miracle Wash Waterless Wash and Wax Spray provides a fantastic shine and protection against the sun’s UV rays without the need for water.
The 2001 Acura NSX stands as a testament to Japanese engineering and automotive design, representing a unique era where performance and reliability were seamlessly blended. This iconic mid-engine sports car was the first Honda-badged product to bear the Acura name and the brand’s first production mid-engine sports car. Powered by a naturally aspirated 3.0-liter V-6 engine, the NSX was celebrated for its smooth power delivery and lightweight aluminum body construction. The vehicle was co-developed with legendary driver Ayrton Senna, which added a significant layer of prestige and performance pedigree to the model. Its design focused on providing a driver that feels natural and connected to the road, avoiding the overly aggressive or difficult handling characteristics common in other supercars of the early 2000s. The NSX’s aluminum chassis was a technological breakthrough at the time, contributing to its reputation for exceptional handling and stability. Owners of this vehicle often cite the car’s unique blend of high-speed stability and everyday drivability as its greatest asset. The engine’s V-6 configuration, known as the C30A1, was renowned for its high-revving nature and linear power curve, making it a favorite among driving enthusiasts. This car was not just a machine for speed but a refined machine for the driver who appreciated precision engineering. Its production ran from 1990 to 2005, with the 2001 model year representing a mature iteration of the first generation, featuring subtle updates that improved reliability and driving dynamics. The NSX is often regarded as the car that challenged the European dominance in the supercar market, proving that a Japanese manufacturer could build a vehicle that competed with the best in the world. Its legacy is defined by a “race car for the road” philosophy that emphasized user-friendliness alongside raw performance, making it a beloved classic that continues to command respect in the automotive community today.
Caring for a 2001 Acura NSX requires a commitment to using the highest quality lubricants to preserve its intricate mechanical components.
