The engine compartment of the 2012 Acura MDX houses the J37A1, a 3.7-liter V-6 engine that has earned a reputation for reliability and smooth power delivery. Proper lubrication is the lifeblood of this powerplant. When you choose AMSOIL Signature Series 5W-20 100% Synthetic Motor Oil, you are selecting a fluid capable of withstanding the rigors of highway driving, towing loads, and cold starts. This oil is guaranteed for up to 25,000 miles or one year, whichever comes first, based on independent testing. It offers significantly more engine protection against horsepower loss and wear compared to conventional oils. For owners looking for a balance between performance and value, the AMSOIL OE 5W-20 Synthetic Motor Oil outperforms conventional oils and provides excellent protection against sludge. If your vehicle has accumulated significant mileage, the AMSOIL 5W-20 100% Synthetic High-Mileage Motor Oil is the ideal choice, featuring enhanced anti-wear additives and reduced sludge to help engines last longer. The associated filtration is just as critical; the AMSOIL Oil Filter (EA15K13-EA) allows for lower restriction to keep engine parts lubricated and captures 99% of contaminants at 20 microns, a standard that helps reduce wear and extends the life of the engine oil.
Beyond the engine, the automatic transmission in the 2012 Acura MDX requires precise fluid characteristics to ensure smooth shifting and longevity. The 6-speed automatic transmission (MT4A) is complex and benefits greatly from synthetic lubrication. The AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is designed to withstand the heat generated during heavy towing and challenging terrain. It remains fluid even in sub-zero temperatures, ensuring quick shifting and protecting internal components from wear. The AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid offers a reliable alternative for those seeking high-performance protection without the premium price tag. Both fluids are formulated to handle the specific demands of the vehicle’s transmission system, preventing the buildup of sludge and maintaining optimal hydraulic pressure for smooth operation.
For vehicles equipped with a transfer case, such as the four-wheel-drive variants of the MDX, proper gear lubrication is vital. The transfer case typically requires a GL-5 rated lubricant for limited-slip differentials and GL-4 for specific components. The AMSOIL SEVERE GEAR 80W-90 100% Synthetic Gear Lube is a versatile choice that contains friction modifiers for limited-slip applications, helping to reduce operating temperatures and extend the life of seals. The AMSOIL SEVERE GEAR 75W-90 100% Synthetic Gear Lube offers similar advanced protection against wear while controlling thermal runaway. For manual transmission applications, the AMSOIL 75W-90 Manual Transmission & Transaxle Gear Lube provides outstanding cold-flow properties and protects brass synchronizers. Each of these lubricants inhibits rust and corrosion, ensuring that the drivetrain components remain protected against the elements and harsh driving conditions.
The cooling system of the MDX plays a crucial role in maintaining engine temperature, especially under load or in extreme weather. The vehicle requires a coolant that can prevent corrosion and freeze. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a 50/50 pre-mix formulation that protects all cooling system metals, gaskets, and hoses for up to 150,000 miles or five years. For those who prefer a concentrate or a safer, non-toxic option, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant exceeds OEM standards for metallic corrosion and erosion. Both products are phosphate-, nitrate-, nitrite-, silicate-, borate-, and amine-free, ensuring compatibility with all other antifreeze and coolant colors and providing long-term protection for the cooling system.
Ensuring the braking system remains responsive is another key aspect of vehicle maintenance. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid offers excellent ABS and traction-control responsiveness. It provides a stable viscosity over a wide temperature range, which is critical for safe braking performance in both hot and cold conditions. This fluid helps prevent brake fade and ensures that the braking system reacts quickly to driver inputs, contributing to overall vehicle safety.
