The 2016 Chevrolet Silverado 1500 Pickup equipped with the 4.3L V6 engine is a capable workhorse known for its balance of fuel economy and utility. Keeping this truck running smoothly requires more than just standard maintenance; it demands the use of fluids specifically designed to handle the rigors of both daily commuting and heavy hauling. The 4.3L V6, identified by engine code LV3, is a robust powerplant, but like any internal combustion engine, it relies entirely on the quality of lubricants to minimize wear, manage heat, and maximize fuel efficiency. Neglecting fluid health can lead to premature component failure, reduced performance, and costly repairs down the road.
AMSOIL synthetic lubricants are engineered to outperform traditional oils, providing superior protection in extreme temperatures and under heavy loads. Whether you are towing a trailer, navigating steep terrain, or pushing the vehicle to its maximum capacity, high-quality synthetic fluids reduce friction and keep your engine running cleaner and cooler. Below, we outline the best AMSOIL products and fluid capacities tailored specifically for the 2016 Silverado 1500 with the 4.3L engine.
Recommended AMSOIL Products
When selecting the right motor oil for your Silverado 1500, you have several options depending on your driving habits and how long you plan to extend your oil change intervals. The engine requires 5W-30 viscosity, and the total capacity is 6.0 quarts, including a filter change.

Essential Cooling and Transmission Fluids
Automotive fluid management is a holistic process. The cooling system in the 2016 Silverado 1500 requires a robust antifreeze solution to handle the temperature swings often encountered by truck owners. The engine cooling system has a capacity of 16 quarts. AMSOIL offers two primary solutions: the AMSOIL Passenger Car & Light Truck Antifreeze & Coolant, which is a 50/50 pre-mix formulation ready to pour, or the AMSOIL Propylene Glycol Antifreeze and Engine Coolant, a concentrated option that requires mixing with water. Both offer protection for up to 150,000 miles or five years and safeguard against rust, corrosion, and erosion, ensuring the cooling system operates at peak efficiency.
The transmission is the heart of power transfer for your Silverado. For the 6-speed automatic transmission (6L80), the initial fill capacity is 6 quarts, though a total fill requires 12.2 quarts. To maintain smooth shifting and protect against heat-related degradation during heavy towing, use the AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid. It remains fluid in sub-zero temperatures and resists oxidation, making it ideal for severe service. Alternatively, the AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid provides reliable protection against wear while meeting OEM performance standards.
Drivetrain and Brake System Lubrication
The durability of the drivetrain depends heavily on the quality of the gear lube used in the differentials and transfer case. For the 8.25-inch rear axle, the capacity is 3 pints, and for the 8.6-inch, 9.5-inch, and 9.76-inch axles, capacities range from 4.3 to 5.5 pints. The AMSOIL SEVERE GEAR® 75W-90 100% Synthetic Gear Lube is excellent for the front axle, offering advanced protection against wear and thermal runaway. For the rear axles, especially those specified for 75W-85, the AMSOIL SEVERE GEAR® 75W-85 100% Synthetic Gear Lube is the recommended choice, providing long oil and seal life with friction modifiers for limited-slip applications.
Safety is paramount, and the brake system relies on high-performance fluid to function correctly. The Silverado 1500 utilizes a DOT 3 hydraulic brake system. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid ensures excellent ABS and traction-control responsiveness. It maintains a stable viscosity over a wide temperature range, preventing brake fade and ensuring consistent pedal feel in all conditions.
Additional Performance Enhancers
To further optimize the fuel economy and engine health of your Silverado, consider the AMSOIL P.i.® Performance Improver Gasoline Additive. This additive can restore up to 14% of horsepower by cleaning GDI fuel injectors to 100% flow rate and reducing pre-ignition knock. For seasonal storage, the AMSOIL Gasoline Stabilizer keeps fuel fresh for up to 12 months, preventing varnish and gum buildup, while the AMSOIL Engine Fogging Oil protects internal components from rust during long periods of inactivity.
Vehicle Background
The 2016 Chevrolet Silverado 1500 stands as a cornerstone of the American light-duty truck market, continuing the legacy of the Silverado nameplate which dates back to the late 1990s. Produced at GM’s manufacturing plants in Texas and Tennessee, this model year represents the fourth generation of the Silverado platform, which debuted in 2014 with a focus on reducing weight and improving aerodynamics to boost fuel efficiency without sacrificing strength.
The specific model discussed here, equipped with the 4.3L EcoTec3 V6 engine, is a favorite among those who need a capable truck but prioritize fuel economy over raw V8 power. This engine, known for its cylinder deactivation technology, allows the truck to run on fewer cylinders during light throttle conditions, saving fuel in stop-and-go traffic. Despite being a six-cylinder, the 4.3L is not a weakling; it provides ample torque for daily hauling, towing, and navigating the kinds of terrains that Silverado owners often encounter. The 2016 model year also saw continued updates to the interior, offering improved infotainment systems and ergonomic designs that made it a comfortable daily driver for many families and small business owners. Whether used for light construction work, tailgating, or long-distance commuting, the 2016 Silverado 1500 4.3L remains a versatile and reliable vehicle that rewards owners who treat it with high-quality lubricants and proper maintenance.
