Engine Oil Specifications and Capacities
The heart of your 2007 Honda S2000 is the F22C1 engine, a 2.2-liter inline-four naturally aspirated unit that revs with a distinctive roar. To keep this engine running at peak performance, selecting the right viscosity is crucial. For temperatures above -20°C, the recommended SAE viscosity is 10W-30. In colder climates where temperatures drop below -20°C, 5W-40 is an acceptable alternative. When performing a standard oil change, the engine requires 4.8 quarts of oil without a filter, and a total of 5.1 quarts when the oil filter is replaced. It is vital to refill to the correct level and then check the oil level after the refill to ensure proper lubrication coverage.
AMSOIL offers four distinct 10W-30 synthetic motor oil options to suit different driving styles and vehicle conditions. The Signature Series is the premium choice, delivering up to 25,000 miles of protection. It contains 75% more engine protection against horsepower loss and wear compared to conventional oils, making it ideal for high-stress driving. The Extended-Life version is perfect for drivers who prefer longer intervals, offering 20,000 miles of protection while providing 37% more cleaning power to keep the engine internals free of deposits. For those on a budget or following standard maintenance schedules, the OE formulation outperforms conventional oils and meets the highest industry standards. Finally, the High-Mileage variant is specifically designed for vehicles with over 75,000 miles, featuring boosted detergents and anti-wear additives to help reduce sludge and seal leaks.
Transmission and Differential Maintenance
The S2000 is renowned for its manual transmission, a 6-speed unit that requires precise fluid characteristics for smooth shifting. The manufacturer recommends a specific fluid, but AMSOIL Synthetic Synchromesh Transmission Fluid is a superior alternative for owners seeking enhanced performance. This 5W-30 fluid is formulated to reduce friction, heat, and wear while resisting oxidation and acid buildup. It improves cold-weather shifting and maximizes fuel economy. The capacity for the manual transmission is 3.2 pints.
The rear differential also requires attention to ensure reliable power delivery. The factory recommendation is a GL-5 90-weight gear lubricant. AMSOIL offers three specialized gear lubes for this application. The SEVERE GEAR 80W-90 is an excellent choice for general use, offering advanced protection against wear and thermal runaway. The 75W-90 and 75W-110 variants provide even lower cold-start viscosity or higher viscosity for extreme conditions, respectively. All three formulations contain friction modifiers suitable for limited-slip differentials and are designed to extend the life of seals and equipment. The rear differential capacity is 1.6 pints. Regular fluid changes are essential to maintain the integrity of the differential gears and bearings.
Cooling, Brakes, and Fluid Systems
Maintaining the cooling system is critical for a high-revving engine like the F22C1. The cooling system capacity for the 2007 S2000 is 6.8 quarts. AMSOIL offers two excellent antifreeze options. The Passenger Car & Light Truck Antifreeze & Coolant is a 50/50 pre-mixed ethylene glycol formulation that provides protection for up to 150,000 miles or 5 years. It is phosphate-, nitrate-, and silicate-free, making it safe for all cooling system metals. For those who prefer a concentrated option, the Propylene Glycol Antifreeze can be mixed with distilled water and offers even longer protection intervals for heavy-duty or extended life applications.
Brake fluid safety is paramount for a performance car. The S2000 uses a DOT 3 fluid. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is an outstanding choice, providing a stable viscosity over a wide temperature range. This ensures excellent responsiveness for the ABS and traction control systems, allowing the driver to brake with confidence even under extreme driving conditions. Using a synthetic brake fluid helps prevent moisture absorption, which can lead to boiling and brake fade during hard stops.
Additional Care and Protection
Beyond the primary fluids, keeping your S2000 in pristine condition involves addressing fuel system cleanliness and general maintenance needs. The AMSOIL P.i.® Performance Improver Gasoline Additive is a powerful tool for maintaining the S2000’s fuel injectors, restoring up to 14% of horsepower and correcting flow rates in GDI engines. It helps prevent carbon buildup and pre-ignition knock, ensuring the engine responds crisply to every throttle input.
For seasonal storage, the AMSOIL Engine Fogging Oil is essential for protecting internal components from rust during long periods of inactivity. Additionally, the AMSOIL Gasoline Stabilizer can keep fuel fresh for up to 12 months, protecting against varnish and gum buildup caused by ethanol corrosion. To keep the vehicle looking as good as it drives, AMSOIL offers a range of car care products, including the Miracle Wash Waterless Wash and Wax Spray for a fantastic shine without soap or water, and various cleaners for brakes, glass, and engines.
About the Vehicle
The 2007 Honda S2000 represents the pinnacle of the second-generation (AP2) model, continuing the legacy of one of the most beloved roadsters of the early 21st century. Born from the racing ambitions of Honda, the S2000 was designed to be a pure driving machine, focusing on lightweight construction, precise handling, and a naturally aspirated engine that could rev to the sky. The platform, often referred to by its chassis codes AP1 and AP2, features a mid-mounted engine layout that provides near-perfect 50/50 weight distribution. This configuration allows the car to change direction with an agility that rivals sports cars costing significantly more.
Powered by the F20C or F22C engine, depending on the year and market, the S2000 earned a reputation for its unique power delivery. The F22C1 in the 2007 model year produces a healthy output of horsepower, but the true magic lies in the sound and the ability to spin the engine to its redline. The engine was designed to operate at exceptionally high temperatures and RPMs, a characteristic that places significant stress on the lubrication system. This is why using a high-quality synthetic oil is not just a recommendation but a necessity for longevity. The car’s suspension geometry and steering rack offer feedback that is rare in modern vehicles, connecting the driver intimately with the road surface.
Owners of the S2000 often cite several common issues that can arise as the car ages, particularly due to the aggressive nature of the engine. One known problem is valve stem seal wear, which can lead to oil consumption as the seals harden over time. Synthetic motor oils with advanced seal conditioning properties, such as AMSOIL’s High-Mileage formulation, can help slow this process and reduce blue smoke. Another frequent concern is the wear on the differential gears, especially in high-mileage vehicles that have seen spirited driving; switching to a high-performance synthetic gear lube can mitigate noise and improve shift smoothness in the limited-slip differential. Additionally, the S2000 is prone to clutch wear and shudder due to the lightweight flywheel and high engagement loads, where fluid contamination or lack of proper maintenance can exacerbate the issue. Finally, cooling system inefficiencies or coolant degradation can lead to overheating, a critical issue for the high-compression engine. Regular flushing and replacing with a high-quality antifreeze can prevent these thermal management problems. Addressing these specific wear points with premium synthetic lubricants can significantly extend the life and enjoyment of this iconic sports car.
In summary, the 2007 Honda S2000 is a driver’s car that rewards proper care. By selecting the right AMSOIL synthetic products, you ensure that every component, from the piston rings to the differential gears, receives the protection it needs to handle the rigors of performance driving. Whether you are chasing the horizon on a back road or maintaining a classic for the long haul, the right fluids make all the difference.
