When it comes to engine protection for your 2012 Acura TSX, the choice of oil grade is critical. The K24Z3 engine is designed to run on 0W-20 viscosity, a specification that ensures optimal flow during cold starts and proper film strength at operating temperatures. Switching to a high-quality synthetic formulation like the Signature Series can significantly reduce wear on internal components. AMSOIL products undergo rigorous industry-standard testing to ensure they meet or exceed the performance requirements of modern Honda and Acura engines.
Oil change intervals are where synthetics truly shine. While conventional oils might require changes every 5,000 miles, AMSOIL Extended-Life motor oil is engineered to provide guaranteed protection for up to 20,000 miles or one year, whichever comes first. For those looking for a balance between performance and budget, the Extended-Life series offers protection for 20,000 miles. Vehicles with higher mileage, typically over 75,000 miles, benefit from the High-Mileage formula, which includes enhanced anti-wear additives and detergents to help clean sludge and prevent oil consumption.
Matching the oil with a high-efficiency filter is just as important as the oil itself. The AMSOIL Oil Filter is designed with greater capacity for small, wear-causing contaminants compared to competing filters. With a filtration efficiency of 99 percent at 20 microns, it keeps the oil cleaner for longer, reducing the strain on the engine. Alternatively, the WIX Oil Filter serves as a reliable premium media option that offers improvements over stock OEM-branded filters, ensuring debris does not recirculate through the engine.
Transmission and Cooling Systems
The transmission fluid in your Acura TSX plays a vital role in shifting quality and longevity. Whether you have the automatic 5-speed M8SA or the manual 6-speed S8RM, using the correct fluid is essential. For automatic transmissions, the Signature Series Fuel-Efficient fluid remains stable even under heavy towing or challenging terrain, preventing sludge buildup and providing reserve protection during extreme use. It is formulated to withstand the rigors of the transmission while maintaining fluidity in cold weather.
For manual transmissions, AMSOIL 5W-30 Manual Synchromesh Transmission Fluid offers maximum protection. It resists oxidation and acid buildup while maximizing fuel economy. This fluid is particularly noted for improving cold weather shifting, ensuring smooth gear changes even when temperatures drop. The capacity for manual transmission fluid is approximately 4 pints, a small amount that highlights the importance of using a high-quality fluid to maximize the benefits.
Cooling system maintenance is equally important to prevent overheating and corrosion. The 2012 Acura TSX requires an antifreeze that can handle long intervals between changes. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant uses a unique OAT formulation that is compatible with a wide variety of cooling systems and free of phosphates, nitrates, and silicates. It offers protection for up to 150,000 miles or 5 years. If you prefer a concentrated coolant that requires mixing with distilled water, the Propylene Glycol Antifreeze provides robust protection against corrosion and erosion, safely protecting all cooling system metals, gaskets, and hoses.
Maintenance and Other Fluids
While less discussed, brake fluid is a critical safety component. Moisture absorption in standard brake fluids can lower the boiling point and lead to reduced braking performance. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is an excellent alternative that provides stable viscosity over a wide temperature range. It ensures excellent ABS and traction-control responsiveness, giving you confidence in stopping power regardless of the driving conditions.
For those looking to optimize fuel economy or prepare the vehicle for storage, additional additives can provide significant benefits. AMSOIL P.i.® Performance Improver is a gasoline additive that can restore up to 14% of horsepower and clean fuel injectors, which is particularly useful for vehicles that may have been using lower-quality fuel. For seasonal storage, AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, preventing the varnish and gum buildup that can clog fuel systems. Similarly, AMSOIL Engine Fogging Oil can be used to protect internal engine components during long periods of inactivity.
