The heart of your vehicle, the 2.0L engine code 2000cc L, requires a precise amount of lubricant to function at peak efficiency. For an oil change that includes the filter, the system capacity is 4.5 quarts. It is important to note that the torque specification for the oil drain plug should be tightened to between 22 and 30 ft/lbs. Selecting a fluid that exceeds the minimum requirements helps maintain engine cleanliness and reduces wear over time. AMSOIL Signature Series 5W-20 100% Synthetic Motor Oil is particularly effective, offering 75% more engine protection against horsepower loss and wear compared to industry standards. If your vehicle has accumulated significant mileage, the AMSOIL 5W-20 100% Synthetic High-Mileage Motor Oil is designed to reduce sludge by 67% and boost the detergent package to keep the engine clean.
Beyond the engine, the cooling system requires specific attention to prevent overheating. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant capacity varies depending on the heater configuration; systems with a heater require 7.9 quarts, while those without require 7.3 quarts. This formulation is a unique poly-organic acid (OAT) that protects all cooling system metals, gaskets, and hoses. It is compatible with other antifreeze colors and is free of phosphates, nitrates, and other harmful additives. Alternatively, the concentrated AMSOIL Propylene Glycol Antifreeze and Engine Coolant can be mixed with water for those who prefer a custom blend, offering protection up to 150,000 miles.
Transmission and AMSOIL 75W-90 Manual Transmission & Transaxle Gear Lube Specifications
Proper transmission fluid is critical for shifting smoothness and longevity. For the 4-speed automatic transmission (SL027), the total fill capacity is 7.6 quarts. AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid prevents the formation of harmful sludge and ensures performance in sub-zero temperatures. If your 2007 MAZDA3 is equipped with a manual transmission, such as the G35M-R 5-speed, the capacity is 6.1 pints. Depending on the specific requirement of the transmission (GL-4 or GL-5) and the ambient temperature, various gear lubes are available. The AMSOIL 75W-90 Manual Transmission & Transaxle Gear Lube offers excellent cold-flow properties and protects brass synchronizers. For more severe conditions, the AMSOIL SEVERE GEAR® 80W-90 100% Synthetic Gear Lube provides advanced protection against wear and thermal runaway, with options ranging from 75W-90 to 80W-90 and 75W-110.
The braking system also benefits from high-quality fluids. The vehicle utilizes hydraulic AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid, specifically DOT 3 or DOT 4. This fluid is formulated to provide excellent responsiveness for ABS and traction control systems, ensuring consistent pedal feel in both hot and cold conditions.
Additional Maintenance and Fuel Additives
Maintaining the air intake system is just as important as lubrication. The WIX Air Filter (part number 42612) features premium media that outperforms many OEM filters, ensuring the engine breathes freely. For fuel system maintenance, AMSOIL P.i. Performance Improver Gasoline Additive is a highly effective solution. It restores up to 14% horsepower and cleans GDI fuel injectors to 100% flow rate after just one tank of fuel. This additive helps prevent carbon buildup, improves fuel economy, and reduces the need for higher-octane fuel, making it a valuable addition to your maintenance routine.
Vehicle Background
The 2007 Mazda MAZDA3 stands as a testament to the brand’s commitment to “Zoom-Zoom,” a philosophy that prioritizes the joy of driving. Launched globally as the successor to the 323/Family 3, the first-generation MAZDA3 (known as the BL chassis in some markets) redefined the compact car segment by blending sporty handling with practical utility. Available as a sedan, a hatchback, and a 5-door wagon, the 2007 model year offered buyers a versatile choice that felt larger and more refined than many of its contemporaries. The vehicle is built on the Mazda Global Platform (GP), which was designed to offer a rigid chassis that enhances handling dynamics while providing a comfortable ride quality.
Under the hood, the 2.0L 4-cylinder engine (Engine Code 2000cc L) was the most common powertrain for the North American market during this period. It delivered a balanced output of power and efficiency, typically generating around 140 to 150 horsepower, which provided ample acceleration for city driving and merging on highways. The engine was known for its reliability, though like any internal combustion engine, it requires regular maintenance to stay healthy. The 2.0L engine was often paired with either a 5-speed manual or a 4-speed automatic transmission, both of which were durable but benefited greatly from the use of high-quality synthetic lubricants to maintain shift quality and reduce internal friction.
Enthusiasts of the MAZDA3 appreciate its balanced chassis tuning. The suspension setup, often featuring MacPherson struts in the front and a torsion beam in the rear, provided excellent road feedback without being overly harsh. This setup allowed the car to handle corners with confidence, making it a favorite among drivers who enjoy a more engaging driving experience compared to the typical “floaty” feel of other compact sedans of the era. The design of the interior was driver-focused, with controls positioned logically to keep the driver’s eyes on the road.
However, owners of the 2007 MAZDA3 may encounter a few specific issues over time, particularly as the vehicle accumulates mileage. One common area of concern is the buildup of carbon deposits, especially on intake valves. While this engine uses port fuel injection which is less prone to direct injection carbon issues than some modern engines, long-term use can still lead to slight efficiency losses. Using fuel additives like AMSOIL P.i. Performance Improver can help mitigate this. Another potential issue is cooling system leaks or degradation of hoses and seals, which is why using a high-performance antifreeze like AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is beneficial for preserving the integrity of the rubber components. Additionally, the power steering system, which uses automatic transmission fluid in some configurations, can develop leaks or shudder over time if the fluid degrades; switching to a AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid can help restore smooth operation. Finally, older manual transmissions may develop “grittiness” in the shifter or a noisy synchronizer if the AMSOIL SEVERE GEAR® 75W-90 100% Synthetic Gear Lube has broken down. Using a friction-modified synthetic AMSOIL SEVERE GEAR® 75W-110 100% Synthetic Gear Lube can help silence these noises and ensure crisp shifts for years to come.
