Additionally, the rear differential requires attention, with a capacity of just 1.5 pints. Using AMSOIL SEVERE GEAR® 75W-90 100% Synthetic Gear Lube in the differential helps control thermal runaway and protects gears from wear, extending the life of the drivetrain components.
Enhancing Performance with Fuel Additives
To complement the mechanical protection provided by synthetic oils, the use of fuel additives can further enhance the performance of the 1.2L engine. The AMSOIL P.i. Performance Improver Gasoline Additive is a powerful tool for maintaining injector flow. In vehicles with Direct Injection (GDI) systems, carbon buildup can occur on the intake valves and injectors over time. This additive restores injectors to 100% flow rate, which can improve fuel economy and power output. It is particularly effective in preventing the carbon buildup that can lead to pre-ignition knock, a condition that can be detrimental to turbocharged engines. By keeping the fuel system clean, you ensure that the engine receives the precise amount of fuel it needs for optimal combustion.

One of the most appealing aspects of the Trailblazer is its versatile interior. The vehicle offers a “Magic Seat” feature, allowing the rear seat to be folded up, creating a unique space for storing tall items while still retaining seating for rear passengers. This design element makes the Trailblazer particularly practical for urban environments where cargo versatility is often a priority. The exterior design draws inspiration from the larger, more rugged Chevrolet Tahoe and Silverado, giving it a bold and assertive look that stands out in the city. Despite its compact dimensions, the Trailblazer offers a surprisingly spacious interior, with generous headroom and legroom for both front and rear occupants.
Owners of the 2022 Trailblazer often cite the vehicle’s responsive handling and comfortable ride as key reasons for their satisfaction. The suspension tuning is designed to absorb road imperfections effectively, making it a comfortable choice for daily commutes and weekend getaways. However, the turbocharged 1.2L engine, while efficient, can be sensitive to oil quality and filter performance. High temperatures generated by the turbocharger require lubricants that can withstand thermal stress without breaking down. This is where high-quality synthetic motor oils make a significant difference, ensuring that the engine remains protected even under demanding driving conditions. Whether you choose the Signature Series for maximum protection or the AMSOIL OE for OEM-recommended performance, your engine will benefit from the advanced formulation.
While the 2022 Trailblazer is a well-regarded vehicle, it is not without its potential issues that regular maintenance can help mitigate. One common concern with turbocharged engines is the potential for oil sludge buildup if non-synthetic oils are used or if oil changes are delayed. Proper lubrication with AMSOIL OE or Extended-Life synthetic motor oils helps prevent this buildup, ensuring that oil passages remain clear. Another issue that can arise is low-speed pre-ignition (LSPI), a condition where the fuel-air mixture ignites prematurely, causing engine knocking and potential damage. Synthetic oils with LSPI-suppressing additives are specifically formulated to combat this issue, protecting the turbocharger and pistons from excessive stress. The AMSOIL P.i. Gasoline Additive can also help keep the fuel system clean to minimize this risk.
Additionally, the transmission system, particularly the CVT or the 9-speed automatic, can benefit from regular fluid changes to prevent shift shudder or harshness. Over time, transmission fluid can degrade and lose its ability to provide proper lubrication and friction modification. Using a dedicated synthetic transmission fluid like the 100% Synthetic CVT Fluid or the Signature Series Fuel-Efficient ATF can extend the life of the transmission and maintain smooth shifting characteristics. Finally, the cooling system, while robust, can suffer from corrosion over time if the coolant is not regularly changed. Using a high-performance antifreeze like AMSOIL Passenger Car & Light Truck Antifreeze & Coolant can prevent corrosion and extend the life of the water pump, radiator, and engine block, ensuring the vehicle stays cool and runs efficiently throughout its service life.
