Understanding Engine Oil Requirements for the 2016 MAZDA3
The heart of the 2016 Mazda MAZDA3 is the 2.0-liter four-cylinder engine, specifically noted by engine code [7] 7. This engine relies on a precise viscosity grade to operate efficiently. The manufacturer recommends a 0W-20 viscosity for optimal fuel economy and protection. The oil capacity for a complete change, including the filter replacement, is 4.4 quarts. Ensuring the correct oil level after refill is vital, as is tightening the drain plug to the specified torque of 23-30 ft/lbs.
While AMSOIL Signature Series 0W-20 synthetic oils are recommended, they are not strictly required by warranty guidelines if the manufacturer’s schedule is followed. However, for owners seeking maximum performance, the benefits are substantial. The Signature Series 0W-20 stands out for its ability to provide up to 75% more engine protection against horsepower loss and wear compared to conventional oils. It is designed to handle extreme temperatures and extended drain intervals, offering peace of mind for drivers who push their vehicles or travel long distances.
For those interested in a balance of performance and value, the Extended-Life 0W-20 offers a robust cleaning package that helps maintain engine smoothness. It boasts a guaranteed protection period of 20,000 miles, making it ideal for regular drivers who want to extend intervals without sacrificing cleanliness. The engine is also prone to Low-Speed Pre-Ignition (LSPI) in certain conditions; AMSOIL Extended-Life testing has shown superior protection against this phenomenon, safeguarding internal components from premature wear.
If the vehicle has accumulated significant mileage, the 0W-20 100% Synthetic High-Mileage Motor Oil is an excellent choice. This formula includes enhanced anti-wear additives and a boosted detergent package designed to reduce sludge by 67%. It helps older engines perform better and last longer by cleaning out deposits that may have accumulated over time. Paired with the AMSOIL Oil Filter, which filters 99% of contaminants at 20 microns, the engine sees a level of cleanliness that standard filters cannot match.
Cooling System and Transmission Fluids
Proper thermal management is just as critical as lubrication for the longevity of the MAZDA3’s powertrain. The cooling system capacity varies depending on the specific transmission configuration, ranging from 6.7 quarts to 7.3 quarts. Maintaining the correct coolant type is essential to prevent corrosion and ensure the engine operates within its ideal temperature range.
The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a unique poly-organic acid (OAT) formulation designed for a wide variety of vehicles. It is an ethylene glycol 50/50 pre-mix that provides up to 150,000 miles of protection or five years of service. This formulation is phosphate-, nitrate-, nitrite-, silicate-, borate-, and amine-free, making it safe for all cooling system metals, gaskets, and hoses. For those who prefer a concentrated option, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers similar long-lasting protection and must be mixed with distilled or high-quality water before use.
Transmission health is equally important. The 2016 MAZDA3 utilizes a 6-speed FW6A-EL automatic transmission. For automatic fluid changes, the initial fill capacity is approximately 3.7 quarts, though total fill capacity can range between 3.5 and 4.9 liters, with a full flush requiring up to 8.2 quarts. Standard oils may break down under the heat of city driving or towing. The Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is engineered to withstand these rigors. It remains fluid in sub-zero temperatures and provides reserve protection during heavy use. The AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is a cost-effective alternative that still delivers excellent protection against wear.
Brake Fluid and Essential Additives
Safety systems like the brakes should never be compromised. The MAZDA3 uses a hydraulic brake fluid system compatible with DOT 3 standards. Over time, brake fluid absorbs moisture, which lowers its boiling point and can lead to reduced performance. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid maintains a stable viscosity over a wide temperature range, ensuring excellent ABS and traction-control responsiveness. This brake fluid resists boiling and moisture absorption better than conventional fluids, keeping the brake system responsive in all conditions.
For fuel system maintenance, the AMSOIL P.i. Performance Improver Gasoline Additive is highly recommended. This fuel injector cleaner can restore up to 14% horsepower and clean GDI fuel injectors to 100% flow rate after just one tank of treated fuel. It helps improve fuel economy and reduces the need for higher-octane fuel while controlling pre-ignition knock.
Seasonal Storage and Additional Care
When the vehicle is not in regular use, proper storage prevents degradation. The AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, fighting ethanol corrosion and preventing varnish buildup. For engine protection during storage, the AMSOIL Engine Fogging Oil is a highly effective rust preventive that protects internal components from corrosion during long periods of inactivity.
Regular maintenance also extends to the exterior and undercarriage. The AMSOIL Miracle Wash Waterless Wash and Wax Spray offers a quick and effective way to clean the vehicle while providing a protective finish that repels dust. For cleaning brake components, the AMSOIL Brake and Parts Cleaner quickly removes oil, grease, and brake fluid without leaving residue, helping eliminate squeal and chatter. The AMSOIL Engine Degreaser is a professional-strength formula that removes the toughest grease and grime from engine surfaces, making it easy to clean under the hood.
