Engine Oil and Filtration Specifications
The heart of your 2016 GMC Sierra 1500 is the 5.3L V-8 engine, specifically the L83 variant found in this model year. Maintaining this powertrain requires fluids that can handle high stress, extreme temperatures, and the varying demands of towing or hauling heavy loads. For this engine, the recommended oil viscosity is 0W-20. The system holds 8.0 quarts of oil when the filter is replaced. It is crucial to verify the oil level after the refill, as adding the exact capacity is necessary for proper lubrication and longevity.
Choosing the right oil grade is vital for fuel efficiency and engine protection. The 0W-20 viscosity ensures the oil flows quickly at cold starts while maintaining a protective film at operating temperatures. AMSOIL offers several options to suit the specific needs of your truck. The Signature Series 0W-20 stands as the top tier, engineered for 100% synthetic protection that can last up to 25,000 miles or one year. This option is ideal for those who push their vehicle hard, offering 75% more protection against horsepower loss and wear compared to conventional oils.
For owners seeking a balance between performance and value, the Extended-Life 0W-20 provides a guaranteed 20,000 miles of protection. This formulation includes 37% more cleaning power than the OE version, helping to keep the engine internals cleaner and reducing the risk of deposit buildup over time. If your vehicle is still under warranty or you prefer to stick strictly to the mileage intervals prescribed by the manufacturer, the OE 0W-20 is an excellent choice. It outperforms conventional oils and is specifically formulated to meet GM dexos1 Gen 2 specifications, offering strong protection against Low Speed Pre-Ignition (LSPI) events common in modern turbocharged and direct-injection engines.
Should your Sierra 1500 have accumulated significant mileage, specifically over 75,000 miles, the High-Mileage 0W-20 motor oil is the specialized solution. This synthetic oil features a unique chemistry designed to address the needs of aging engines. It includes a boosted detergent and dispersant package to reduce sludge by 67%, helping to clean out accumulated deposits. Enhanced anti-wear additives and seal conditioners help reduce oil consumption and prevent leaks, while still providing a guaranteed 12,000 miles of protection for normal service.
Filtration is just as critical as the oil itself. A high-quality filter ensures that contaminants are removed from the oil before they can circulate and cause damage. The AMSOIL Oil Filter, part number EAO17, is engineered to provide 99 percent filtering efficiency at 20 microns. This level of filtration is superior to many competitors, capturing smaller particles that can cause wear on bearings and other sensitive components. The filter also features a greater capacity for contaminants, extending its service life to match the extended oil change intervals of the synthetic oils. For those who prefer aftermarket options, the WIX XP Oil Filter offers premium media that improves upon OEM-branded filters, ensuring consistent flow and filtration. The standard WIX Oil Filter is also a solid choice, delivering reliable performance with premium media for effective debris capture.
Transmission and Drivetrain Fluids
The automatic transmission in your GMC Sierra 1500 is a key component that benefits greatly from high-performance synthetic fluids. The 2016 model typically features either the 6L80 or 8L90 transmission, depending on the specific configuration. For the 6L80, the total fill capacity is 12.2 quarts, though an initial fill requires only 6 quarts. For the 8L90, the total fill capacity is 11.4 quarts with an initial fill of 7.4 quarts. Keeping these components lubricated with the correct fluid prevents wear, sludge formation, and temperature-related issues.
AMSOIL offers transmission fluids designed to withstand the rigors of heavy towing, off-road use, and elevated temperatures. The Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is a top-tier choice, capable of remaining fluid in sub-zero temperatures while providing reserve protection during heavy use and abuse. It is engineered to protect against wear and ensure smooth shifting cycles, extending the life of the transmission. The OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is another strong option, providing protection against wear while meeting the efficiency requirements of modern drivetrains.
The transfer case and differentials in your 4×4 Sierra require specialized lubrication to handle the torque and stress of four-wheel drive operations. The transfer case typically requires a specific amount of lubricant depending on the model, such as 3.2 pints for certain configurations. For the front differential, which may be an 8.25 RG unit, the capacity is approximately 3 pints. The rear differentials vary in capacity depending on the ring and pinion size, such as 4.2 pints for an 8.6 RG or 5.5 pints for 9.5 RG and 9.76 RG units.
To protect these gears, AMSOIL SEVERE GEAR® 75W-90 and 75W-85 100% Synthetic Gear Lubricants are highly recommended. The 75W-90 is suitable for applications requiring this viscosity, offering advanced protection against wear and helping to control thermal runaway. It contains friction modifiers specifically beneficial for limited-slip differentials. The 75W-85 is often the recommended grade for rear axles that specify GM P/N 19300457, ensuring proper lubrication for the gear teeth and bearings while reducing operating temperatures and protecting against rust and corrosion.
Coolant and Brake Fluid Requirements
Maintaining the cooling system is essential for the longevity of the engine, particularly in a heavy-duty truck that generates significant heat. The cooling system capacity for the 2016 GMC Sierra 1500 with the 5.3L engine is 16.6 quarts. Using a high-quality antifreeze and coolant is crucial to prevent corrosion, freezing, and boiling. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a 50/50 pre-mix formulation that is phosphate-free, nitrate-free, nitrite-free, silicate-free, borate-free, and amine-free. This unique OAT formulation protects all cooling system metals, gaskets, and hoses, providing up to 150,000 miles or five years of protection.
For those who prefer a concentrated coolant, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers exceptional performance. It is designed to greatly surpass standards for metallic corrosion and erosion and is compatible with all other antifreeze colors. This coolant provides protection up to 150,000 miles or five years in passenger cars and light trucks, making it a versatile and durable choice for your GMC Sierra.
Braking performance is non-negotiable for safety. The hydraulic brake fluid in your vehicle must maintain stability under high temperatures to prevent brake fade. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is an ideal replacement. It offers excellent responsiveness for ABS and traction control systems, ensuring a stable viscosity over a wide temperature range. This synthetic fluid outperforms conventional DOT 3 and DOT 4 fluids, providing superior protection against moisture contamination and ensuring safe, reliable braking.
