Maintaining the 2016 Chevrolet Colorado with its 2.5L inline-four engine requires more than just a basic oil change. The LCV A engine, found in models ranging from the base work truck to the LT trim, relies on precise fluid specifications to deliver the fuel economy and reliability expected from a compact pickup. Because GM updated its Dexos 1 specification to Gen 3 during this era, using a synthetic oil that meets these stringent standards is critical for preventing sludge, protecting turbochargers from coking, and ensuring the longevity of internal components. Proper lubrication extends service intervals and keeps the engine running smoothly under the stress of hauling, towing, or navigating rough terrain.

Engine Oil and Filtration Specifications
The heart of the 2016 Chevrolet Colorado with the 2.5L engine is the LCV A powerplant, which requires a 5W-20 viscosity oil to ensure proper lubrication during cold starts and protection at operating temperatures. The oil capacity for this engine is 5.0 quarts when the AMSOIL Oil Filter is replaced. It is essential to refill to this exact amount and check the oil level after the refill to ensure accurate measurement. The oil drain plug should be torqued to 18 ft-lbs to prevent leaks or stripping. While the vehicle was originally designed around GM Dexos 1 Gen 2 specifications, the current standard has been updated to GM Dexos 1 Gen 3. AMSOIL synthetic motor oils meet and exceed these updated requirements, ensuring compatibility with modern emission systems and engine tolerances.
For the oil filter, the AMSOIL Oil Filter (EA15K50-EA) is the recommended choice for maximum filtration. It is designed with a media that captures 99 percent of particles at 20 microns, significantly reducing wear on engine components. This filter offers greater capacity for small, wear-causing contaminants compared to many competing filters and allows for extended service intervals without compromising flow. For owners who prefer a premium aftermarket brand, the WIX Oil Filter (WL10290-EA) is also a valid option, offering premium media that outperforms many OEM-branded filters in terms of durability and filtration efficiency.
Transmission and Differential Protection
Protecting the transmission and drivetrain is just as important as engine maintenance. The 2016 Colorado with the 2.5L engine often comes equipped with a 6-speed automatic transmission (6L50). For vehicles with this transmission, the total fluid capacity for a complete flush is 11.2 quarts, while an initial fill requires 6.7 quarts. AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is designed to withstand the high temperatures and mechanical stress associated with heavy towing and challenging terrain. It helps maintain optimal fluidity in sub-zero temperatures, ensuring smooth shifts regardless of the season.
For those preferring an OE-focused option, the AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is another excellent choice. Moving to the drivetrain, the differential and transfer case require specific gear lubricants. The front differential typically holds 2.7 pints, while the rear differential varies based on the gear ratio. For models with an 8.00 RG (Rear Gear), the capacity is 3 pints, and for the 8.60 RG, it is also 3 pints. The transfer case capacity is listed as 4 pints. In all these cases, AMSOIL SEVERE GEAR® 75W-90 100% Synthetic Gear Lube is the recommended product. This lubricant contains friction modifiers specifically designed for limited-slip applications, helps reduce operating temperatures, and protects against rust and corrosion, extending the life of seals and gears.
Brake Fluid and Coolant Systems
The braking system of the 2016 Colorado benefits significantly from switching to a synthetic brake fluid. The vehicle requires a DOT 3 hydraulic brake fluid. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is an ideal replacement that provides superior ABS and traction-control responsiveness. Unlike conventional fluids that can absorb moisture and boil under heavy braking, this synthetic fluid maintains a stable viscosity over a wide temperature range, ensuring consistent pedal feel and stopping power.
Coolant management is critical for the longevity of the 2.5L engine. The system holds a capacity of 9.6 quarts. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a ready-to-use, 50/50 pre-mix formulation that protects all cooling system metals, gaskets, and hoses for up to 150,000 miles or five years. It is free of phosphates, nitrates, nitrites, silicates, and borates, making it safe for all engine types. Alternatively, for those who prefer to mix their own, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers a concentrated solution. This option provides even longer protection, up to 150,000 miles, and is phosphate-free, offering excellent corrosion and erosion protection without the harsh chemicals found in some traditional coolants.
Additional Maintenance and Care
For drivers looking to maximize fuel economy and engine performance, adding AMSOIL P.i.® Performance Improver Gasoline Additive can be beneficial. This additive helps restore up to 14% horsepower and cleans GDI fuel injectors to 100% flow rate after just one tank of fuel. It is compatible with capless fuel systems and helps control pre-ignition knock. For seasonal storage, AMSOIL Gasoline Stabilizer can keep fuel fresh for up to 12 months, preventing varnish and gum buildup caused by ethanol corrosion.
