The 6.2L L87 V8 engine in the 2022 GMC Sierra 1500 is a robust powerhouse capable of delivering significant torque for work and play. However, this displacement and performance come with a requirement for precise lubrication. The engine oil capacity is 8.0 quarts when including a filter change. It is critical to check the oil level after refilling to ensure the correct volume is present, as the system relies on a precise amount to circulate oil effectively to the pistons, crankshaft, and cylinder heads. The oil drain plug requires a torque of 18 ft/lbs, and the seal should be replaced to prevent leaks.
One of the most important aspects of maintaining this engine is selecting the correct viscosity. While the GM manual may specify 0W-20, the vehicle manufacturer has issued safety recall bulletin N252494001 for certain model years including the 2022. This bulletin addresses potential issues with engine oil viscosity selection. Consequently, for vehicles in this recall program, AMSOIL Signature Series 100% Synthetic Motor Oil in 0W-40 is the recommended correct oil. This thicker viscosity provides a more robust film strength at high operating temperatures, which is vital for the 6.2L engine under stress. Whether you choose the AMSOIL Signature Series 0W-20 for standard driving or the 0W-40 for enhanced protection or recall compliance, both are fully synthetic and far superior to conventional oils in terms of thermal stability and resistance to oxidation.
The cooling system in the 2022 Sierra 1500 also demands attention. With a capacity of 13.3 quarts, the cooling system benefits from a high-quality antifreeze. Using a phosphate-, nitrate-, and silicate-free OAT formulation helps protect the various metals in the engine block and radiator while ensuring long service intervals. This reduces the frequency of flushes required and maintains consistent temperature regulation, which is essential for preventing overheating during heavy towing or hauling loads. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant offers protection up to 150,000 miles or 5 years, making it a durable choice for this application.
Beyond the engine, the 10-speed automatic transmission is a critical component. Whether you have the 10L80/MHS transmission with a cooler, which holds 12 quarts total, or the trans-only variant holding 11.6 quarts, synthetic transmission fluid is the best choice. Conventional fluids can break down under the extreme heat generated by the torque converter and heavy gear shifting. The AMSOIL Signature Series ULV 100% Synthetic Automatic Transmission Fluid is engineered to handle the rigors of heavy towing and elevated temperatures while maintaining fluidity in cold starts, ensuring smooth shifts and prolonged transmission life. For fuel-efficient needs, the AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is also available.
About the Vehicle
The 2022 GMC Sierra 1500 Pickup stands as a pillar in the full-size pickup truck market, blending traditional rugged capability with modern refinement. As part of the General Motors T1XX platform, which it shares with the Chevrolet Silverado 1500, the Sierra has evolved into a highly sophisticated vehicle that competes aggressively with the Ford F-150 and Ram 1500. The 6.2L V8 engine is one of the most popular powertrain options, offering a blend of brute force and efficiency that appeals to a wide range of users, from fleet managers to weekend off-roaders.
For owners, the appeal of the 2022 Sierra 1500 lies in its versatile cabin and advanced technology. The interior is typically well-appointed, featuring high-quality materials and a modern infotainment system, often with the latest connectivity options. The ride quality has improved significantly in recent generations, offering a suspension that can toggle between a comfortable daily driver mode and a more robust stance when loaded with cargo or towing a boat. The 6.2L engine, with its Dynamic Fuel Management system, attempts to balance power with fuel economy by deactivating cylinders when full power isn’t needed, a feature that requires high-quality oil to function correctly during the transition cycles.
However, with any heavy-duty work truck comes a set of known challenges that owners must navigate. One of the primary concerns with the 6.2L V8 engine has been related to carbon buildup, particularly on the intake valves of Gas Direct Injection (GDI) engines. Over time, this carbon accumulation can affect fuel economy and engine performance. Using a high-detergent synthetic oil and periodic use of a fuel system cleaner like AMSOIL P.i. Performance Improver Gasoline Additive can help mitigate this issue, restoring injectors to near 100% flow rate and reducing the need for costly higher-octane fuel. This additive is compatible with capless fuel systems and helps prevent carbon rap and pre-ignition knock.
Another common issue observed in modern GM trucks involves the cooling system. Radiator leaks or water pump failures can occur earlier than expected, leading to overheating. The use of a premium antifreeze that is compatible with all cooling system metals is crucial to extending the life of the radiator, hoses, and gaskets. A robust cooling fluid prevents corrosion and erosion, which are the root causes of many coolant-related failures.
Transmission reliability is also a frequent topic among Sierra owners. The 10-speed automatic transmission is sophisticated, but some users have reported harsh shifting or software-related glitches, especially when the vehicle is used for frequent heavy towing. Synthetic transmission fluid plays a vital role here, providing better thermal stability and lubrication than factory-fill fluids, which helps to reduce shift shocks and protect internal clutches and bearings from premature wear.
Finally, suspension and chassis components, particularly in models used for off-road recovery or heavy-duty work, can suffer from premature wear or squeaking due to exposed bushings and joints. Grease these points regularly with a high-performance synthetic multi-purpose grease, such as AMSOIL Synthetic Multi-Purpose Grease, to resist washing out and maintain protection against corrosion. For vehicles exposed to road salt, using a heavy-duty metal protector like AMSOIL Heavy-Duty Metal Protector on the undercarriage can provide a wax-like barrier that significantly slows down rust and corrosion, keeping the truck’s body and frame in better condition for years to come. Additionally, AMSOIL Silicone Spray can protect rubber and locking out moisture, keeping seals pliable.
In summary, the 2022 GMC Sierra 1500 with the 6.2L engine is a capable and powerful truck that rewards diligent maintenance. By choosing the right synthetic lubricants, owners can address common pain points like carbon buildup, cooling issues, and transmission stress, ensuring that their vehicle remains a reliable workhorse or leisure vehicle for the long haul. Whether tackling a construction site or a mountain trail, proper lubrication is the key to unlocking the full potential of this impressive machine. Regular cleaning with AMSOIL Brake and Parts Cleaner or AMSOIL High-Foam Car Shampoo will also help keep the vehicle looking its best.
