For drivers who prefer a fluid that closely aligns with original equipment manufacturer expectations without the premium price point, the AMSOIL OE 5W-30 100% Synthetic Motor Oil is a robust option. It is designed to fight sludge and deposits effectively, utilizing a 100% synthetic formulation that meets GM dexos1 Gen 2 specification requirements. Furthermore, AMSOIL has conducted testing showing zero LSPI (Low-Speed Pre-Ignition) events in their OE 5W-30 oil during tests required by GM, adding an extra layer of confidence in its durability. If your Blazer has surpassed 75,000 miles, the AMSOIL 5W-30 100% Synthetic High-Mileage Motor Oil is the superior choice. It features unique chemistry with boosted detergents and dispersants that have demonstrated a 67% reduction in sludge, helping the engine last longer and perform better.
The oil change process for the Blazer is straightforward, requiring a total capacity of 6.0 quarts when changing both the oil and the filter. It is critical to check the oil level after the refill to ensure the correct level is reached. When replacing the drain plug, the torque specification should be set to 18 ft/lbs. Additionally, replacing the drain plug seal is recommended to prevent leaks. Paired with the oil, the AMSOIL Oil Filter provides exceptional filtration, capturing small, wear-causing contaminants with greater capacity than competing filters. Its high efficiency at 20 microns helps reduce engine wear and extends the life of the internal components.
Antifreeze & Coolant Requirements
The cooling system in the 2023 Blazer is substantial, requiring a capacity of 13.7 quarts. Maintaining the correct thermal balance is vital to prevent overheating and corrosion, especially given the potential for high loads on the V6 engine. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a 50/50 pre-mix formulation that protects all cooling system metals, gaskets, and hoses. It features a unique poly-organic acid (OAT) formulation that allows for extended use in a wide variety of vehicles, providing protection for up to 150,000 miles or 5 years. For those who prefer a concentrated solution, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers versatility. It is phosphate-, nitrate-, nitrite-, silicate-, borate-, and amine-free, ensuring compatibility with all other antifreeze colors and preventing corrosion in heavy-duty applications.
Transmission and Differential Protection
The 2023 Chevrolet Blazer with the 3.6L engine is equipped with a 9-speed 9T65 automatic transmission. Proper fluid selection here is crucial for shifting smoothness and transmission longevity. The total fill capacity is approximately 10 quarts, with an initial fill capacity of 5.3 quarts (actual capacity ranging between 5.0-6.0 liters). The AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is designed to withstand the rigors of heavy towing, elevated temperatures, and challenging terrain. It remains fluid even in sub-zero temperatures, providing reserve protection during heavy use.
