Engine Oil Selection and Specifications
The heart of the 2014 Subaru BRZ is the 2.0-liter horizontally opposed four-cylinder engine, known internally as the FA20D4. This engine is designed for high revs and responsive power delivery. To maintain the precise tolerances required for the FA20D4, AMSOIL recommends using a 0W-20 viscosity motor oil. The correct oil grade ensures rapid lubrication at cold starts and a stable oil film at the high operating temperatures of a performance sports car.
For owners seeking the ultimate in engine protection, the AMSOIL Signature Series 0W-20 100% Synthetic Motor Oil is the top choice. This formulation is engineered to offer 75% more engine protection against horsepower loss and wear compared to conventional standards. It provides a service interval of up to 25,000 miles or one year, making it an economical choice for the high-performance enthusiast who wants to minimize maintenance interruptions without compromising on safety. It is suitable for any driving condition, from daily commuting to track days.
For those who prefer a balance between premium performance and value, the AMSOIL Extended-Life 0W-20 100% Synthetic Motor Oil offers up to 20,000 miles of guaranteed protection. This oil contains enhanced cleaning power to help keep the engine running smoother for longer. It protects against Low-Speed Pre-Ignition (LSPI), a condition that can cause engine damage, ensuring the engine’s integrity is maintained over the life of the oil.
The AMSOIL OE 0W-20 100% Synthetic Motor Oil is another excellent option, designed to outperform conventional oils while meeting the mileage expectations of the original equipment manufacturer. It fights sludge and deposits effectively, providing a reliable alternative for those who follow standard service intervals. For vehicles with over 75,000 miles, the AMSOIL 0W-20 100% Synthetic High-Mileage Motor Oil is the recommended choice. It features a unique chemistry with boosted detergents and dispersants, along with enhanced anti-wear additives. This formulation has demonstrated a 67% reduction in sludge, helping to clean the engine and improve performance in older BRZs.
When performing an oil change, the 2014 Subaru BRZ requires a total capacity of 5.7 quarts, including the filter replacement. This figure is critical for ensuring the engine is properly lubricated without overfilling. The oil drain plug should be torqued to 31 ft/lbs, and a new washer should always be installed on the drain bolt to prevent leaks.
Filtration and Air Intake Systems
Even the best motor oil cannot protect an engine if it is being pulled through a clogged or inefficient filter. The AMSOIL Oil Filter is designed to work in tandem with the synthetic oils mentioned above. It provides filtering efficiency of 99 percent at 20 microns, which means it captures small wear-causing contaminants that other filters allow to pass through. This increased capacity for small particles helps reduce engine wear and extends the life of the oil by keeping it cleaner for longer.
Alongside the oil filter, maintaining a clean air intake is vital for the efficiency of the FA20D4 engine. The WIX Air Filter is recommended for this application. Featuring premium media, it offers improvements over original equipment manufacturer-branded filters, ensuring that the engine receives a steady supply of clean air. This is particularly important for performance vehicles where optimal airflow translates directly to power and fuel economy.
Transmission and Differential Fluids
The 2014 Subaru BRZ is available with either a 6-speed automatic or a 6-speed manual transmission. Both require specific fluids to ensure smooth shifting and longevity. For automatic transmissions, the capacity is 7.9 quarts for a total fill, with an initial fill of 2.1 quarts. The AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is ideal for these transmissions. It remains fluid in sub-zero temperatures and provides reserve protection during heavy use, making it suitable for the spirited driving that the BRZ is known for.
For owners of the manual transmission variant, the AMSOIL 75W-90 Manual Transmission & Transaxle Gear Lube is the recommended fluid. The capacity is 4.6 pints for the 6-speed manual. This gear lube protects against increased heat and pressure while offering outstanding cold-flow properties. It is friction-modified to ensure excellent seal compatibility and protects brass synchronizers from wear, which is crucial for the precision shifting that manual transmission owners value.
The 2014 Subaru BRZ often features a Limited Slip Differential (LSD) in the rear. To protect this component, the AMSOIL SEVERE GEAR 75W-90 100% Synthetic Gear Lube is specifically formulated with friction modifiers for limited-slip applications. It controls thermal runaway, a common issue in sporty driving, and helps reduce operating temperatures. This fluid protects against rust and corrosion, ensuring the differential operates smoothly and quietly.
Coolant, Brake Fluid, and Seasonal Maintenance
Maintaining the correct thermal balance is essential for the longevity of the BRZ’s engine. The cooling system capacity varies slightly by transmission type: approximately 7.6 quarts for manual and 7.9 quarts for automatic. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant offers a unique poly-organic acid (OAT) formulation that protects all cooling system metals, gaskets, and hoses. It is phosphate-, nitrate-, and silicate-free, providing protection up to 150,000 miles or five years.
For those who prefer a concentrated solution, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant is available. This product is highly effective against metallic corrosion and erosion, greatly surpassing industry standards. It requires mixing with distilled water and offers protection for up to 150,000 miles in passenger cars.
Braking performance is a safety-critical component of any sports car. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid provides excellent ABS and traction-control responsiveness. Its stable viscosity over a wide temperature range ensures that the brake pedal remains firm and responsive even under heavy use, a key feature for a vehicle like the BRZ.
For seasonal storage, the AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, protecting against varnish and gum buildup. Additionally, the AMSOIL Engine Fogging Oil is an effective rust preventive for protecting internal engine components during long periods of inactivity.
About the Vehicle
The 2014 Subaru BRZ represents a significant moment in the automotive world, marking the return of the classic, rear-wheel-drive sports coupe formula in an era dominated by front-wheel-drive economy cars and SUVs. Developed in collaboration with Toyota, the BRZ shares its platform and powertrain with the Toyota 86, yet it maintains its own distinct identity as a pure driving machine. Under the hood lies the 2.0-liter Boxer engine, a horizontally opposed four-cylinder configuration that Subaru is famous for. This layout offers a low center of gravity, which is crucial for handling dynamics, allowing the driver to take corners with confidence and precision.
The 2014 model year was the first full year of production for the second generation of the BRZ (following the initial 2013 launch), and it brought refined updates to the chassis and suspension. Owners often praise the BRZ for its communicative steering and balanced weight distribution, which provide a driving experience that feels engaging and rewarding rather than merely functional. The rear-wheel-drive layout allows for controlled oversteer and drift capabilities, making it a favorite among amateur track day enthusiasts and driving clubs.
While the horsepower figures may not rival supercars, the BRZ makes up for it with lightweight construction and exceptional agility. It is a car that demands involvement from the driver, rewarding skill and attention with predictable, linear responses. The 2014 model is particularly noted for its reliability and the simplicity of its maintenance schedule compared to more complex modern performance vehicles. For owners, maintaining this car involves keeping the fluids fresh and the filters clean to preserve the balance and responsiveness that define the Subaru BRZ experience.
By selecting the right AMSOIL products, you ensure that your 2014 Subaru BRZ continues to deliver the performance and reliability it was built for. Whether you are taking it to the track, enjoying a weekend drive, or simply commuting to work, the protection provided by these high-performance lubricants gives you the confidence to push the vehicle to its limits safely.
