For the 2009 Honda S2000, the engine oil capacity is 5.1 quarts when including a filter change, dropping to 4.8 quarts if the filter is not replaced. Always ensure the 10W-30 viscosity is used, which is preferred for temperatures above -20°C. If operating in extreme cold below -20°C, a 5W-40 grade may be considered. It is critical to check the oil level after refilling and to torque the oil drain plug to the specified 29 ft/lbs to prevent leaks or damage to the aluminum pan.
Beyond the engine, the transmission and cooling systems of the S2000 require specialized attention. The six-speed manual transmission benefits from a fluid designed to handle the friction and heat of aggressive shifting. The required AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is formulated to protect the cooling system metals, gaskets, and hoses for up to 150,000 miles or 5 years. For those requiring a concentrated solution, AMSOIL Propylene Glycol Antifreeze and Engine Coolant is available, offering protection up to 150,000 miles in passenger cars. The system capacity requires 8 quarts of AMSOIL Passenger Car & Light Truck Antifreeze & Coolant to ensure proper thermal management during spirited driving on the track or winding roads.
The manual transmission fluid requirement for the 6-speed gearbox is covered by AMSOIL 5W-30 Manual Synchromesh Transmission Fluid. This fluid is engineered for synchromesh transmissions, reducing friction and heat while resisting oxidation and acid buildup. The system requires 3.2 pints of fluid. For the rear differential, which requires GL-5 lubricant, AMSOIL offers a range of Severe Gear 80W-90 100% Synthetic Gear Lube. Whether you choose the 75W-90 or the 75W-110 grade, these products provide advanced protection against wear, thermal runaway, and rust, ensuring smooth power delivery to the rear wheels. The rear differential holds 1.6 pints of fluid.
Brake performance is critical for a car of the S2000’s stature. The recommended choice is AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid, providing excellent responsiveness for ABS and traction control systems while maintaining stable viscosity across a wide temperature range. This fluid is compatible with the Honda Heavy Duty Brake Fluid DOT 3 specification often found in this vehicle’s service literature.
Maintaining the longevity of the fuel system and overall cleanliness of the vehicle is equally important. AMSOIL P.i.® Performance Improver is a powerful additive that can restore up to 14% horsepower and clean GDI fuel injectors to 100% flow rate. For seasonal storage, AMSOIL Gasoline Stabilizer keeps fuel fresh for up to 12 months, while AMSOIL Engine Fogging Oil protects internal components from rust during periods of inactivity. Owners can also utilize AMSOIL Engine Degreaser to remove heavy grease and grime from the engine bay, keeping the high-output F22C1 engine looking pristine.
Vehicle Background
The Honda S2000 occupies a unique place in automotive history as a pure, front-engine, rear-wheel-drive roadster that emphasizes driver engagement above all else. Produced between 1999 and 2009, this vehicle was the spiritual successor to the iconic 2000cc F20 and the 2500cc F22 engines from the 1980s, culminating in the 2.2-liter F22C1 used in the 2009 model year. It was widely celebrated for its high-revving engine, which could reach nearly 9,000 RPM, delivering a screaming, race-car-like exhaust note that became its signature. The chassis was designed by Honda’s racing division, providing sharp handling and precise steering that made it a favorite among driving enthusiasts and track day participants.
This generation of the S2000 featured a slightly larger engine compared to its predecessor, the AP1, offering a bit more low-end torque while retaining the high-RPM character that defined the model line. Its lightweight aluminum-intensive construction contributed to an impressive power-to-weight ratio, making it one of the most capable sports cars of its era. Despite its age, the S2000 remains highly sought after by collectors and driving purists who value its mechanical purity and lack of electronic intervention. The 2009 model marked the end of an era, closing the production run of this legendary roadster. Proper maintenance with high-quality lubricants is essential for these aging vehicles to continue providing a thrilling driving experience for years to come.
When performing maintenance, it is vital to select the right oil change kit to ensure all components are covered. Kits are available that bundle the motor oil, filter, and coolant, simplifying the process of keeping the S2000 in top condition. By utilizing AMSOIL synthetic lubricants, owners can extend service intervals and provide superior protection against the harsh operating conditions of a high-performance engine. Whether tackling long highway drives, spirited weekend runs, or storage periods, the range of AMSOIL products ensures comprehensive care for the 2009 Honda S2000’s engine, transmission, differential, and brake systems.
