Keeping your 2016 Scion FR-S running at its peak requires more than just a quick visit to the garage; it demands the right lubricants selected specifically for the unique engineering of the FA20 engine. This sports coupe is designed for responsiveness and driver engagement, relying on precise tolerances and high-revving performance that conventional fluids simply cannot support over the long term. Using the correct viscosity and formulation ensures that critical components receive adequate protection during aggressive driving, spirited cornering, and daily commuting, while also maintaining optimal fuel economy and engine cleanliness.
Recommended AMSOIL Products
Choosing the right lubricants for this vehicle involves matching the fluid’s characteristics to the engine’s design specifications and the driving conditions you encounter. For the 2016 Scion FR-S with its 2.0-liter 4-cylinder FA20 engine, AMSOIL offers a comprehensive lineup of synthetic products designed to exceed factory requirements. Whether you are looking for maximum protection, extended drain intervals, or cost-effective performance, there is a specific product tailored to your needs.
At the top of our recommendations is the AMSOIL Signature Series 0W-20 100% Synthetic Motor Oil. This premium oil provides unsurpassed protection against horsepower loss and wear, offering up to 25,000 miles of guaranteed service intervals in severe service. It is formulated to handle the high temperatures and stresses generated by the FA20 engine, making it an excellent choice for drivers who push their vehicle or live in extreme climates.
For those who prioritize extended service intervals without sacrificing performance, the AMSOIL Extended-Life 0W-20 100% Synthetic Motor Oil is an outstanding alternative. It delivers up to 20,000 miles of protection and features enhanced cleaning power to keep the engine running smoothly over time. This option is ideal for drivers who want the benefits of synthetic technology with slightly less frequent changes than the Signature Series.
If your driving habits are less severe or you are looking for a reliable option that outperforms conventional oils at a more accessible price point, consider the AMSOIL OE 0W-20 100% Synthetic Motor Oil. It is designed to fight sludge and deposits while providing solid protection for the engine, offering a cost-effective solution that maintains the integrity of your vehicle’s lubrication system.
For vehicles with over 75,000 miles, the AMSOIL 0W-20 100% Synthetic High-Mileage Motor Oil is specifically formulated to address the needs of aging engines. It contains a boosted detergent package and enhanced anti-wear additives to reduce sludge by 67%, helping to clean internal components and maintain oil consumption control.
Complementing these oils, the AMSOIL Oil Filter is essential for maintaining flow and filtration efficiency. With a capacity for small, wear-causing contaminants, this filter works in tandem with synthetic oil to maximize engine life. Additionally, ensuring proper airflow is critical for performance, which is why the WIX Air Filter is included in the recommended list, offering premium media that improves upon OEM specifications.
Engine and Cooling System Protection
The engine oil capacity for the 2016 Scion FR-S FA20 engine is 5.7 quarts when including the filter. It is crucial to verify the oil level after refilling, as the fill capacity can vary slightly depending on the specific service procedures followed. The engine operates most efficiently with the recommended 0W-20 viscosity, which provides excellent starting capability in cold weather while maintaining proper film strength during high-temperature operation.
Proper cooling system maintenance is just as vital as engine lubrication. The cooling system capacity varies depending on the transmission type, with the automatic transmission requiring 7.9 quarts and the manual transmission requiring 7.6 quarts. To ensure the cooling system remains corrosion-free and effective for up to 150,000 miles or 5 years, the AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a superior choice. This ethylene glycol-based, 50/50 pre-mix formulation is phosphate-, nitrate-, and silicate-free, protecting all cooling system metals, gaskets, and hoses without the risk of silicate dropout.
For those who prefer a concentrated formula that requires mixing with distilled water, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers an alternative. This product is designed to greatly surpass industry standards for metallic corrosion and erosion, providing long-lasting protection that can extend up to 150,000 miles or 5 years in passenger vehicles.
Transmission and Driveline Lubrication
The transmission fluid in your 2016 Scion FR-S plays a critical role in ensuring smooth shifts and protecting the internal components from wear. For vehicles equipped with the 6-speed automatic transmission, the total fill capacity is 7.9 quarts. To match the factory specifications while offering superior thermal stability and shift feel, the AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is the top recommendation. It withstands the rigors of heavy towing, elevated temperatures, and challenging terrain, remaining fluid even in sub-zero conditions.
The AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid serves as a cost-effective alternative that also meets fuel efficiency requirements and protects against wear. For those with the manual transmission, which requires 4.6 pints of fluid, the AMSOIL 75W-90 Manual Transmission & Transaxle Gear Lube is highly recommended. This friction-modified lubricant is excellent for protecting brass synchronizers and ensuring long service life, with outstanding cold-flow properties that facilitate easier shifting in cold weather.
For the differential, the requirements depend on whether your vehicle is equipped with a Limited Slip Differential (LSD). For a standard rear differential without LSD, the capacity is 2.4 pints with the LSD option. The AMSOIL SEVERE GEAR® 75W-85 100% Synthetic Gear Lube provides advanced protection against wear, thermal runaway, and rust, while also reducing operating temperatures. It contains friction modifiers specifically beneficial for limited-slip applications. Alternatively, for standard rear differentials, the AMSOIL SEVERE GEAR® 75W-90 100% Synthetic Gear Lube offers robust performance with similar benefits, ensuring long oil and seal life.
Brake Fluid and Vehicle Maintenance
Safety is paramount for any vehicle, and the braking system requires a fluid that maintains stability over a wide temperature range. The 2016 Scion FR-S utilizes a hydraulic brake fluid system requiring DOT 3 specification. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid delivers excellent ABS and traction-control responsiveness while ensuring a stable viscosity that prevents brake fade during aggressive driving.
To keep the vehicle’s performance optimal and fuel system components clean, consider using fuel additives. The AMSOIL P.i.® Performance Improver Gasoline Additive helps restore up to 14% of horsepower by restoring GDI fuel injectors to 100% flow rate after just one tank of fuel. This additive also reduces the need for higher-octane fuel and helps prevent carbon buildup, ensuring the engine continues to perform as intended.
Vehicle Background
The 2016 Scion FR-S is a quintessential sports coupe that represents a unique chapter in automotive history, marking the rebirth of the classic “hatchback coupe” concept.
