The engine of the 2022 Buick ENCORE GX is a compact 1.2-liter turbocharged unit that packs a significant punch relative to its size. To extract the full potential of this engine, the oil must maintain its viscosity index under the extreme heat generated by turbocharging while also flowing quickly during cold starts. The 2022 ENCORE GX requires a 4.2-quart oil capacity when including a filter change. This specific volume ensures that the oil pump can circulate the fluid effectively to all critical moving parts, including the turbocharger bearings which operate at high speeds and temperatures. Without the correct oil grade and volume, the engine’s longevity can be compromised, leading to increased friction and potential premature wear.
Protecting the Transmission and Cooling System
Transmission maintenance is equally critical for this vehicle, as the ENCORE GX utilizes a CVT250 automatic transmission. Unlike traditional gear-based transmissions, the CVT relies on a belt and pulley system that is highly sensitive to fluid degradation. The fluid capacity varies slightly depending on whether the cooler is engaged, with a total fill of 9.1 quarts with the cooler and 8.9 quarts without it. AMSOIL’s 100% Synthetic CVT Fluid is engineered to provide the necessary frictional properties to prevent slip and ensure smooth power delivery, which is vital for the CVT’s longevity.
Similarly, the cooling system must be maintained with precision. The 2022 ENCORE GX requires 6.7 quarts of coolant. Proper coolant formulation is not just about keeping the engine from freezing; it is about preventing corrosion, scale buildup, and overheating. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant uses a unique poly-organic acid technology that is compatible with a wide variety of vehicles. It is phosphate, nitrate, nitrite, silicate, borate, and amine-free, ensuring that it does not react negatively with the metals and rubber hoses in the cooling system. For those who prefer a concentrated fluid, the Propylene Glycol Antifreeze and Engine Coolant offers a robust solution that protects against metallic corrosion and erosion, lasting up to 150,000 miles or five years.
Comprehensive Lubrication for All Components
While the engine and transmission are the heart of the vehicle, other components require attention to ensure a smooth and safe driving experience. The rear differential in the ENCORE GX benefits from AMSOIL SEVERE GEAR® 75W-90 100% Synthetic Gear Lube. This product contains friction modifiers specifically designed for limited-slip applications, helping to reduce wear and control thermal runaway. The capacity for the rear differential is 1.5 pints, a small but crucial amount that keeps the gears lubricated and cool.
Braking systems are another area where synthetic fluids shine. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid ensures stable viscosity over a wide temperature range, which is essential for maintaining consistent brake pedal feel and responsiveness. This fluid offers excellent anti-lock braking system and traction-control responsiveness, giving drivers confidence in various weather conditions. For vehicle owners who plan to store their ENCORE GX for extended periods, AMSOIL Gasoline Stabilizer and AMSOIL Engine Fogging Oil provide additional protection. The stabilizer keeps fuel fresh for up to 12 months, preventing varnish and gum buildup, while the fogging oil protects internal engine components from rust during storage.
Additional Maintenance and Care Products
Beyond standard fluid changes, there are several other products that can help maintain the 2022 ENCORE GX. The AMSOIL P.i.® Performance Improver Gasoline Additive is a powerful tool for restoring up to 14% horsepower and cleaning GDI fuel injectors to 100% flow rate. This additive helps prevent carbon rap and controls pre-ignition knock, which can be beneficial for turbocharged engines. For fuel system maintenance, the Upper Cylinder Lubricant Corrosion Inhibitor lubricates the fuel system and upper cylinders, ensuring smooth operation and preventing corrosion. The Synthetic Multi-Purpose Grease is ideal for chassis lubrication, offering outstanding low-temperature pumpability and long-term performance in all weather conditions.
Exterior and interior maintenance also play a role in the overall care of the vehicle. The Heavy-Duty Metal Protector offers a protective, wax-like coating that resists salt, moisture, and chemical corrosion, ideal for undercoating and hard-to-reach places. The Silicone Spray provides a dry lubricating film that protects rubber and plastic components from cracking and drying, locking out moisture without attracting dust. For cleaning, the Power Foam® Carburetor and Induction-System Cleaner removes deposits from ethanol and degraded fuel, maximizing horsepower and improving fuel economy. The Miracle Wash Waterless Wash and Wax Spray is a convenient option for maintaining a clean finish without soap or water, leaving the vehicle with a protective layer that repels dust and light dirt.
