Essential Engine Oil Specifications
The 2016 Mazda CX-5 with the 2.0L 4-cylinder engine requires a specific oil grade to ensure optimal clearance and flow. The factory recommendation calls for 0W-20 viscosity oil. When performing an oil change, the system requires a total of 4.4 quarts including the filter replacement. It is important to refill the correct amount and check the oil level immediately after refilling to prevent over-filling or under-filling. The oil drain plug should be torqued to between 23-30 ft/lbs to ensure a secure seal without damaging the threads.
AMSOIL offers four distinct formulations of 0W-20 synthetic motor oil to suit various driving needs and vehicle ages. The Signature Series is the premier choice for those seeking the longest possible service intervals, offering up to 25,000 miles of protection. It provides 75% more engine protection against horsepower loss compared to industry standards. For drivers who prefer a balance between premium performance and cost, the Extended-Life option guarantees up to 20,000 miles of protection while offering significant cleaning power. The OE (Original Equipment) version is designed to outperform conventional oils and is a great value for those adhering to standard mileage intervals. Finally, for older vehicles or those seeking added protection against oil consumption, the High-Mileage formula contains a unique chemistry with boosted detergents and dispersants to reduce sludge by 67% and enhance engine longevity.
Transmission and Drivetrain Fluids
Proper maintenance of the automatic transmission is crucial for the smooth operation of your CX-5. This vehicle utilizes a 6-speed automatic transmission (Model FW6A-EL for FWD or FW6AX-EL for AWD). The total fill capacity for the transmission is 8.2 quarts, while the initial fill capacity is approximately 3.7 quarts. The actual amount required for a drain and fill can vary between 3.5L and 4.9L (3.7 to 5.1 quarts) depending on the specific transmission fluid exchange method used.
AMSOIL provides top-tier synthetic transmission fluids for this application. The Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is engineered to withstand the rigors of heavy towing and elevated temperatures. It remains fluid in sub-zero temperatures and provides reserve protection during abusive driving conditions. The OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is a cost-effective alternative that still delivers superior protection against wear and heat, ensuring the longevity of the transmission components. Both fluids help maintain peak shift performance and prevent the sludge buildup that can lead to costly repairs.
For the 4-wheel-drive models, the transfer case and rear differential also require specific lubrication. The transfer case requires 0.8 pints of fluid, and the rear differential requires 1 pint. The recommended torque for the drain and fill plugs is between 30-42 ft/lbs. AMSOIL recommends their SEVERE GEAR® 75W-85 100% Synthetic Gear Lube for these applications. This advanced gear lube controls thermal runaway, which is critical for maintaining the temperature of the gears under load. It contains friction modifiers specifically designed for limited-slip differentials and protects against rust and corrosion, significantly extending the life of the seals and equipment.
Cooling System and Brake Fluid
Keeping the engine at the correct operating temperature is vital for efficiency and preventing overheating. The coolant capacity depends on the specific configuration of the cooling system. For models equipped with the ATXL system, the capacity is 7.9 quarts, while MTXL models require 7.7 quarts. You have two excellent options for this vehicle: AMSOIL Passenger Car & Light Truck Antifreeze & Coolant, which comes as a 50/50 ethylene glycol pre-mix for immediate use, or the AMSOIL Propylene Glycol Antifreeze and Engine Coolant, a concentrated formula that is mixed with distilled water. The Propylene Glycol option is less toxic and offers protection for up to 150,000 miles, while also exceeding standards for metallic corrosion and erosion.
Brake system performance should never be compromised. For the hydraulic brake fluid, AMSOIL recommends their DOT 3 and DOT 4 100% Synthetic Brake Fluid. This fluid ensures excellent responsiveness for ABS and traction control systems. Unlike conventional glycol-based fluids, the synthetic formulation provides a stable viscosity over a wide temperature range, preventing the fluid from boiling under heavy braking and ensuring consistent pedal feel.
Vehicle Background
The 2016 Mazda CX-5 is a compact crossover SUV that represents a significant milestone in Mazda’s design philosophy. Launched as the first vehicle to feature the brand’s “Kodo: Soul of Motion” design language, it quickly gained a reputation for offering a driving dynamic that rivaled luxury brands, despite its affordable price point. For the 2016 model year, the CX-5 was powered by the SkyActiv-G engine family, which was engineered for high compression ratios to maximize thermal efficiency and fuel economy without sacrificing power. The 2.0L 4-cylinder engine found in this specific guide is known for its reliability and smooth power delivery, making it an excellent choice for daily commuting and light towing.
As a compact SUV, the CX-5 strikes a balance between the cargo utility of a traditional SUV and the nimble handling of a sedan. It offers a comfortable ride quality with a spacious interior that accommodates up to five passengers, along with a versatile cargo area that can be expanded by folding the rear seats. The vehicle’s all-wheel-drive system is available on select trims, providing enhanced traction in adverse weather conditions. Owners often cite the intuitive controls and high-quality interior materials as standout features that elevate the driving experience. Whether used for family outings, weekend road trips, or navigating urban environments, the 2016 Mazda CX-5 remains a versatile and capable vehicle that rewards owners with responsive handling and efficient performance when properly maintained.
Seasonal Storage and Additional Care
If your Mazda CX-5 is not driven year-round, or if you need to restore peak performance after long periods of use, AMSOIL offers specialized additives and maintenance products. AMSOIL P.i.® Performance Improver is a gasoline additive that can restore up to 14% horsepower and clean carbon deposits from direct injection fuel injectors after just one tank of fuel. For vehicles that are stored for extended periods, the AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, protecting against varnish and gum buildup, while the AMSOIL Engine Fogging Oil coats internal engine components to prevent rust and corrosion during long-term inactivity.
Regular cleaning and protection of the vehicle’s exterior and undercarriage also contribute to its longevity. The AMSOIL Engine Degreaser is a professional-strength formula that quickly removes grease and grime from engine surfaces without damaging components. For exterior care, AMSOIL Miracle Wash offers a waterless wash and wax solution that cleans and protects the paint finish with UV inhibitors. The AMSOIL Heavy-Duty Degreaser can tackle sticky residues, while AMSOIL Silicone Spray provides a dry lubricating film that prevents the cracking and drying of rubber seals and hoses. These products ensure that your CX-5 looks and performs its best, whether it is on the road or in storage.
Why Proper Lubrication Matters
Using the correct lubricants is not just about following a checklist; it is about maximizing the lifespan of your vehicle’s most expensive components. The synthetic technology used in AMSOIL products creates a protective barrier that is far superior to conventional mineral oils. This protection reduces friction, which in turn reduces wear and heat generation. For the 2016 Mazda CX-5, this means the engine can run cooler, the transmission can shift more smoothly, and the drivetrain can handle stress without premature failure. By extending service intervals, you also reduce the waste of used oil and filters, making your maintenance routine more environmentally friendly.
The investment in premium synthetic lubricants pays off in reduced repair costs and a higher resale value. A well-maintained vehicle with a complete service history using high-quality fluids is far more attractive to potential buyers. Furthermore, the extended protection intervals offer convenience and cost savings over the long term, as you spend less time and money at the shop. Whether you are the first owner or a subsequent owner looking to restore the vehicle’s performance, using AMSOIL products ensures that your 2016 Mazda CX-5 continues to deliver the driving pleasure and reliability that Mazda is known for.
