The 2023 Chevrolet Silverado 1500 Pickup equipped with the 2.7L L3B Turbo engine is a versatile workhorse that combines significant towing capacity with impressive fuel efficiency. However, this turbocharged inline-four engine demands specific lubrication standards to prevent low-speed pre-ignition (LSPI) and ensure durability under load. Whether you are hauling heavy loads, towing a boat, or navigating extreme weather conditions, using the correct oils and filters is essential for maintaining peak performance. AMSOIL Signature Series 5W-30 100% Synthetic Motor Oil, AMSOIL Extended-Life 5W-30 100% Synthetic Motor Oil, and AMSOIL OE 5W-30 100% Synthetic Motor Oil provide a comprehensive range of synthetic lubricants designed to exceed GM dexos1 Gen 2 specifications, offering superior protection and extended service intervals for this vehicle.

Maintaining the 2023 Silverado 1500 Pickup requires attention to more than just the engine oil. The vehicle’s complex cooling system, advanced automatic transmission, and differential assemblies all rely on high-quality synthetic fluids to operate efficiently. The engine oil capacity for this 2.7L turbocharged unit is 6.0 quarts when including a filter change. It is critical to use a 5W-30 viscosity grade that meets the GM dexos1 Gen 2 specification, as failure to do so can lead to engine failure in the turbocharger. AMSOIL 5W-30 100% Synthetic High-Mileage Motor Oil is available for older engines. AMSOIL motor oils are engineered to withstand the high thermal stress of turbocharged engines, providing a stable film strength that reduces friction and wear better than conventional oils.
Transmission and Drivetrain Fluids
The automatic transmission in this model is an 8-speed unit that benefits greatly from high-performance synthetic transmission fluids. For the 8L90 transmission, the total fill capacity with a cooler is approximately 11.4 quarts, while a trans-only fill is around 10.9 quarts. AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is a top choice. This fluid withstands the rigors of heavy towing and elevated temperatures while remaining fluid in sub-zero conditions. For vehicles requiring the ULV specification, the AMSOIL Signature Series ULV 100% Synthetic Automatic Transmission Fluid provides a lower viscosity formulation designed to reduce parasitic drag and improve fuel economy. The AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is also available for those seeking OE compatibility.
The transfer case and differential assemblies also require specialized lubricants. The transfer case, which handles models with MP3015 or 25 specifications, requires a specific capacity of lubricant and should be serviced with a synthetic AMSOIL SEVERE GEAR® 75W-85 100% Synthetic Gear Lube to ensure smooth power delivery. For the front and rear differentials, which are rated for GL-5 or GLSH1 gear oils, AMSOIL recommends the AMSOIL SEVERE GEAR® 75W-85 100% Synthetic Gear Lube. This gear lube contains advanced additives that control thermal runaway, reduce operating temperatures, and protect against rust and corrosion. It also includes friction modifiers for limited-slip applications, ensuring optimal performance in all weather conditions.
Coolant and Brake Fluid Specifications
Keeping the engine at the correct operating temperature is vital for the longevity of the turbocharged components. The cooling system capacity for the 2023 Silverado is 12.5 quarts. For this capacity, owners can choose between the AMSOIL Passenger Car & Light Truck Antifreeze & Coolant, a 50/50 pre-mix formulation that provides protection for up to 150,000 miles, or the AMSOIL Propylene Glycol Antifreeze and Engine Coolant for those who prefer a concentrated formula that can be mixed to exact specifications. Both options are phosphate-, nitrate-, nitrite-, silicate-, borate-, and amine-free, making them safe for all cooling system metals and compatible with all coolant colors.
Brake fluid maintenance is often overlooked but is crucial for safety. The 2023 Silverado requires DOT 4 hydraulic brake fluid. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid offers excellent ABS and traction-control responsiveness. It provides a stable viscosity over a wide temperature range, ensuring consistent braking performance even during heavy use or in extreme cold.
Engine Protection and Additives
For vehicles that have accumulated over 75,000 miles, the AMSOIL 5W-30 100% Synthetic High-Mileage Motor Oil is an excellent choice. It features unique chemistry with boosted detergents and enhanced anti-wear additives to help clean sludge and reduce oil consumption. Additionally, using an additive like the AMSOIL P.i.® Performance Improver Gasoline Additive can help restore fuel injectors and maintain fuel system cleanliness, which is particularly beneficial for GDI engines found in modern trucks. The AMSOIL Upper Cylinder Lubricant Corrosion Inhibitor also provides top-end protection. For seasonal storage, the AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, preventing varnish and gum buildup. The AMSOIL Engine Fogging Oil is another excellent product for storage protection.
