The F20C1 engine in the 2001 S2000 is a high-output, high-revving masterpiece. When selecting a motor oil, it is vital to choose a fluid that can handle the extreme thermal stress generated by the engine at redline. AMSOIL Signature Series 10W-30 100% Synthetic Motor Oil is the top recommendation for those seeking the longest service intervals and maximum protection. For owners of this vehicle with higher mileage, the AMSOIL 10W-30 100% Synthetic High-Mileage Motor Oil offers enhanced anti-wear additives and a boosted detergent package to address the needs of an older engine.
Equally critical is the filtration system. To ensure no contaminants reach the critical components of the VTEC engine, pairing the motor oil with a high-quality filter is essential. The AMSOIL Oil Filter provides superior efficiency and capacity, allowing for reduced restriction and better lubrication. Alternatively, the WIX Oil Filter serves as a premium aftermarket option that complements the performance of AMSOIL synthetic oils.
Transmission and Differential Lubrication
The 2001 Honda S2000 is renowned for its six-speed manual transmission, which offers a precision shift quality that is difficult to match. However, the transmission fluid must be compatible with the Honda Synchromesh requirements to prevent grinding and ensure smooth engagement. The AMSOIL 5W-30 Manual Synchromesh Transmission Fluid is specifically designed for this application, reducing friction and heat while resisting oxidation and varnish buildup that can lead to shifting issues. The capacity for this fluid is 3.2 pints.
The rear differential also requires attention. While the factory specifications allow for GL-5 fluids in all temperatures, synthetic gear lubes provide superior protection against thermal runaway, which can occur during spirited driving on winding roads. The AMSOIL SEVERE GEAR 80W-90 100% Synthetic Gear Lube and AMSOIL SEVERE GEAR 75W-90 100% Synthetic Gear Lube both offer advanced protection and contain friction modifiers beneficial for limited-slip differentials. For those seeking maximum load capacity, the AMSOIL SEVERE GEAR 75W-110 100% Synthetic Gear Lube is an excellent choice. The rear differential capacity is 1.6 pints.
Engine Cooling and Brake System Safety
Maintaining the correct operating temperature is crucial for the longevity of the S2000’s engine. The cooling system requires a robust antifreeze and coolant mixture. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is an ethylene glycol 50/50 pre-mix that exceeds OEM requirements and protects against corrosion, gasket failure, and hose deterioration. It is formulated to be phosphate-, nitrite-, and silicate-free, making it safe for all cooling system metals. For those preferring a concentrated formula, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers up to 150,000 miles of protection when mixed with distilled water. The cooling system capacity is 8 quarts.
Brake performance on a sports car like the S2000 must be absolute. The hydraulic system operates under significant stress, and the use of a high-quality brake fluid ensures consistent pedal feel and ABS responsiveness. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is engineered to maintain a stable viscosity across a wide temperature range, ensuring safety and control. It is compatible with the Honda Heavy Duty Brake Fluid DOT 3 specification.
Additional Fluids and Vehicle Care
To keep the S2000 in peak running condition, additional maintenance products can be highly beneficial. The AMSOIL P.i. Performance Improver Gasoline Additive helps restore horsepower and improves fuel economy by cleaning fuel injectors and combustion chambers. For seasonal storage, the AMSOIL Gasoline Stabilizer keeps fuel fresh for up to 12 months, preventing varnish and gum buildup. Furthermore, the AMSOIL Engine Fogging Oil provides a protective coating on internal engine components during long periods of inactivity.
