The engine is the heart of your CX-3, and the 2.0L four-cylinder engine (Engine Code [7] 7) operates efficiently within a narrow temperature and viscosity window. The factory-recommended viscosity is 0W-20, and the total capacity is 4.4 quarts when the oil filter is replaced. After refilling, it is critical to check the oil level to ensure accuracy. For best results, the oil drain plug should be torqued between 23 and 30 ft/lbs, and a new washer must always be installed on the drain bolt to prevent leaks. AMSOIL Signature Series motor oils in this viscosity grade offer superior flow at low temperatures and maintain a robust lubricating film at high temperatures, reducing friction and improving fuel economy. Extended-Life formulations are ideal for those seeking maximum intervals, while High-Mileage Motor Oil helps engines over 75,000 miles. Whether you are dealing with extreme heat or freezing cold, these synthetic formulations ensure the engine starts quickly and runs smoothly.
Transmission and Drivetrain Maintenance
The automatic transmission in the 2016 Mazda CX-3 is a 6-speed unit, designated as the EW6A-EL. Maintaining this transmission is vital for preserving the smooth shift quality that defines the driving experience of this crossover. The initial fill capacity for the automatic transmission is 3.5 quarts, while a total fill requires 8.2 quarts. Using a high-quality synthetic automatic transmission fluid is crucial to prevent wear, sludge buildup, and heat-related failures. AMSOIL Signature Series Fuel-Efficient Automatic Transmission Fluid and AMSOIL OE Fuel-Efficient Automatic Transmission Fluid are formulated to withstand the rigors of modern transmissions, including elevated temperatures and heavy towing. They remain fluid in sub-zero temperatures and provide a reserve of protection during abuse, ensuring the longevity of the transmission internals.
For vehicles equipped with four-wheel drive, the transfer case requires specific attention. The transfer case fluid capacity is 0.8 pints. Proper lubrication here is essential to prevent wear and tear on the gears and bearings that transfer power to the rear wheels. Similarly, the rear differential, which operates under the GLSC3 specification, requires 0.7 pints of lubricant. AMSOIL SEVERE GEAR 75W-85 100% Synthetic Gear Lube is the ideal choice for both the transfer case and the rear differential. This synthetic gear lube provides advanced protection against wear, controls thermal runaway, and contains friction modifiers that are beneficial for limited-slip applications. By keeping the drivetrain components properly lubricated, you ensure efficient power delivery and reduced operating temperatures.
Cooling System and Brake Safety
The cooling system for the 2016 Mazda CX-3 holds approximately 6.1 quarts of fluid. A healthy cooling system is paramount for engine longevity, preventing overheating and corrosion. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a pre-mixed, 50/50 solution that provides protection for up to 150,000 miles or 5 years. It is a poly-organic acid (OAT) formulation that is free from phosphates, nitrates, and silicates, making it compatible with all cooling system metals and rubber components. For those who prefer a concentrated solution, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers a non-toxic alternative that requires mixing with distilled water. This concentrated formula delivers exceptional corrosion and erosion protection, surpassing industry standards for metallic integrity.
Safety on the road is also dependent on the condition of the braking system. The recommended fluid for the hydraulic brake system in this vehicle is a DOT 3 fluid. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid meets and exceeds DOT 3 and DOT 4 requirements. It features excellent responsiveness for ABS and traction control systems, ensuring that braking power is consistent regardless of temperature. The fluid maintains a stable viscosity across a wide temperature range, which is critical for preventing brake fade during repeated heavy braking. By switching to a synthetic brake fluid, you can improve the feel and reliability of your braking system, contributing to overall vehicle safety.
Seasonal Care and Fuel System Health
For owners who use their vehicle during seasonal changes or store it for periods of inactivity, AMSOIL offers specialized additives and protectants. The AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, preventing varnish and gum buildup that can clog fuel injectors. It is particularly effective at fighting ethanol corrosion, making it ideal for seasonal equipment. Additionally, the AMSOIL Engine Fogging Oil provides a protective layer against rust and corrosion for internal engine components during long-term storage. It is highly effective for protecting engines that may sit idle for extended periods.
The fuel system also plays a significant role in performance. The AMSOIL P.i. AMSOIL P.i. Performance Improver Gasoline Additive is a powerful gasoline additive that can restore up to 14% horsepower and clean GDI fuel injectors to 100% flow rate after just one tank of treated fuel. This additive helps improve fuel economy, reduces the need for higher-octane fuel, and controls pre-ignition knock. It is compatible with capless fuel systems and works to remove harmful deposits that can accumulate over time. For further protection, the AMSOIL Upper Cylinder Lubricant Corrosion Inhibitor lubricates the fuel system and upper cylinders, adding an extra layer of defense against wear and corrosion.
