Maintaining the 5.7L HEMI V8 in your 2016 Ram 1500 requires more than just swapping parts; it demands fluids engineered to withstand the specific thermal and mechanical stresses this engine generates. Whether you are hauling heavy loads, towing across highways, or simply commuting through stop-and-go traffic, the lubrication system is the heart of your truck’s longevity. Proper fluid selection ensures optimal heat dissipation, reduces friction within the transmission and differential, and protects critical components from premature wear. This guide outlines the precise AMSOIL recommendations tailored to the unique requirements of the 2016 Ram 1500 Pickup with the 5.7L 8-cylinder engine.
Recommended AMSOIL Products
- AMSOIL Signature Series 5W-20 100% Synthetic Motor Oil – Offers unparalleled engine protection for up to 25,000 miles with superior thermal stability and cleaning power for your 5.7L HEMI.
- AMSOIL Extended-Life 5W-20 100% Synthetic Motor Oil – Delivers 37% more cleaning power than OE oil and provides 20,000 miles of guaranteed protection with LSPI resistance.
- AMSOIL OE 5W-20 100% Synthetic Motor Oil – A cost-effective synthetic option that outperforms conventional oils and fights sludge and deposits effectively.
- AMSOIL 5W-20 100% Synthetic High-Mileage Motor Oil – Formulated with boosted detergents and anti-wear additives for vehicles exceeding 75,000 miles to reduce sludge and oil consumption.
- WIX Oil Filter – Features premium filtration media that offers improvements over original equipment manufacturer-branded filters for maximum flow and contaminant removal.
The 2016 Ram 1500 with the 5.7L HEMI engine relies heavily on 5W-20 viscosity motor oil to maintain proper lubrication under varying conditions. This specific oil weight is critical for the variable valve timing system and ensuring rapid oil flow during cold starts. When performing an oil change, the engine requires 7.0 quarts of fluid, including the filter. It is essential to torque the drain plug to 25 foot-pounds to ensure a secure seal without damaging the oil pan threads. Regular oil changes using these premium synthetic fluids help mitigate the high heat produced by the HEMI, keeping the piston rings and bearings clean and protected against wear.
Beyond the engine, the cooling system plays a vital role in maintaining performance. The 2016 Ram 1500 cooling system holds 18.3 quarts of antifreeze. For optimal protection against corrosion, erosion, and overheating, either the AMSOIL Passenger Car & Light Truck Antifreeze & Coolant or the AMSOIL Propylene Glycol Antifreeze and Engine Coolant are recommended. The pre-mix formula protects all cooling system metals, gaskets, and hoses, while the concentrated option allows for custom mixing ratios. Both formulations are designed to last up to 150,000 miles or 5 years, providing peace of mind for long hauls and winter driving.
Transmission health is equally crucial for a pickup truck designed for towing and hauling. The 2016 Ram 1500 features several transmission types, including the 6-speed 65RFE (RWD and 4WD) and the 8-speed 8HP70. For these applications, the AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid offers the highest level of protection against the rigors of heavy towing and elevated temperatures. If a multi-vehicle solution is preferred, the AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid provides excellent thermal stability and slip protection. For budget-conscious maintenance without sacrificing quality, the AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid and the AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid are excellent choices that resist sludge and promote smooth, shudder-free shifts.
Finally, the final drive and transfer case lubrication ensures that power is delivered efficiently to the wheels. The front standard differential requires AMSOIL SEVERE GEAR® 75W-85 100% Synthetic Gear Lube, which is ideal for limited-slip applications and controls thermal runaway. The rear differential, whether equipped with or without a limited-slip unit, calls for AMSOIL SEVERE GEAR® 75W-140 100% Synthetic Gear Lube. This heavy-duty gear lube contains friction modifiers to ensure smooth operation in limited-slip differentials, which is a common configuration in the Ram 1500. For the brake system, AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid offers excellent responsiveness and stability over a wide temperature range, ensuring consistent braking performance in all weather conditions.
About the Vehicle
The 2016 Ram 1500 Pickup represents a significant step forward in the full-size truck market, known for its blend of rugged capability and modern refinement. Built on the Ram TX platform, this model year was particularly notable for offering a wide array of powertrain options, including the powerful 5.7-liter HEMI V8 featured in this guide. This engine, equipped with technologies like the Variable Valve Timing (VVT) system, delivers a robust balance of torque and power, making it a favorite among owners for both work duties and recreational towing. The 5.7L engine is renowned for its durability and ability to handle sustained loads, which is why proper lubrication is so critical to its operation.
In terms of performance, the 2016 Ram 1500 was marketed as a leader in ride quality and interior comfort, often challenging more expensive competitors. The suspension tuning was designed to absorb road imperfections while maintaining stability when loaded. The truck features a choice of rear-wheel or four-wheel drive configurations, with the 4WD models utilizing advanced transfer cases to handle off-road conditions and adverse weather. The interior of the 1500 received high praise for its spaciousness and user-friendly technology, making it a popular choice for families and tradespeople alike.
From a historical perspective, the Ram 1500 has long held a strong reputation in the American truck segment, competing directly with the Ford F-150 and Chevrolet Silverado. The 2016 model continued this legacy, offering features like an available eight-speed automatic transmission that improved fuel economy and responsiveness. The truck’s market position is defined by its versatility; it can serve as a heavy-duty workhorse during the week and a comfortable daily driver or family hauler on the weekends. Owners appreciate the truck’s strong resale value and the extensive network of support available for maintenance and parts. By keeping the vehicle in top condition with the correct synthetic fluids, owners can ensure that their Ram 1500 remains a reliable and powerful asset for years to come.
