The 2008 Acura TL with the 3.2-liter V6 (Engine Code J32A3 R) is a sophisticated machine designed for those who demand a balance of performance and reliability. Under the hood, this engine is capable and refined, but like all modern precision engines, it relies heavily on the quality of the lubricants and fluids circulating through its systems. Using the correct viscosity and specification fluids ensures that components like the variable cylinder management system, hydraulic valve lifters, and the 5-speed automatic transmission receive the protection they need to operate smoothly. Neglecting fluid maintenance can lead to premature wear, sludge buildup, and costly repairs, so selecting high-quality synthetic alternatives is a smart investment for any owner.

Starting with the most critical component, the engine, the 2008 Acura TL requires a 5W-20 viscosity oil. The manufacturer specifies a capacity of 4.5 quarts when changing the oil with a filter replacement, with a torque specification of 29 ft-lbs for the drain plug. After refilling, it is essential to check the oil level to ensure it is correct. The AMSOIL engine oil lineup offers flexibility depending on your driving habits and the condition of your vehicle. For the ultimate in performance and extended drain intervals, the AMSOIL Signature Series 5W-20 stands out. It provides unmatched protection against horsepower loss and wear, allowing you to run up to 25,000 miles between changes or one year, whichever comes first. If your vehicle has accumulated significant mileage, the High-Mileage 5W-20 is an ideal solution. Its unique chemistry targets the specific needs of engines over 75,000 miles, reducing sludge and boosting detergency to help the engine perform better and last longer.
Filtration is just as vital as the oil itself. A clogged or inefficient filter can force dirty oil through bypass valves, causing wear to internal engine parts. The AMSOIL Oil Filter is designed with greater capacity for small, wear-causing contaminants and allows for lower restriction, ensuring parts remain lubricated even under pressure. It boasts a filtering efficiency of 99 percent at 20 microns. For those who prefer a well-known aftermarket brand, the WIX Oil Filter is also a compatible option, offering premium media that provides improvements over original equipment manufacturer-branded filters. When replacing the oil, always ensure the filter is seated correctly to prevent leaks and maintain proper flow.
Beyond the engine, the transmission system requires specialized attention. The 2008 Acura TL’s 5-speed automatic transmission benefits significantly from a high-quality synthetic fluid. The total fill capacity is 7.9 quarts, though a drain and fill process typically requires around 3.1 quarts initially. The AMSOIL Signature Series Multi-Vehicle Automatic Transmission Fluid is engineered to handle the rigors of heavy towing, elevated temperatures, and challenging terrain. It remains fluid in sub-zero temperatures and provides reserve protection during heavy use. Alternatively, the OE Multi-Vehicle Automatic Transmission Fluid offers excellent performance, resisting harmful sludge and promoting smooth, shudder-free shifts. Both products help guard against leaks and ensure the transmission operates efficiently for the long haul.
Cooling system maintenance is often overlooked but is critical for preventing overheating, which can lead to catastrophic engine failure. The cooling system capacity for the 2008 Acura TL is approximately 6.7 quarts. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a 50/50 ethylene glycol pre-mix that exceeds original equipment requirements. It is formulated to protect all cooling system metals, gaskets, and hoses, and is free of phosphates, nitrates, and silicates, making it compatible with various vehicle cooling systems. For those who prefer a concentrated propylene glycol antifreeze and engine coolant, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers up to 150,000 miles or 5 years of protection. It greatly surpasses standards for metallic corrosion and erosion, making it a robust choice for maintaining optimal operating temperatures.
The braking system also relies on high-performance fluids to ensure safety. The Acura TL uses a DOT 3 DOT 3 and DOT 4 100% Synthetic Brake Fluid. AMSOIL’s DOT 3 and DOT 4 100% Synthetic Brake Fluid is designed to provide excellent ABS and traction-control responsiveness. Unlike conventional fluids, it maintains a stable viscosity over a wide temperature range, preventing brake fade during heavy use. This ensures consistent stopping power in both winter and summer driving conditions. Regular fluid replacement helps maintain the integrity of seals and prevents moisture buildup, which can lead to corrosion within the brake lines and master cylinder.
About the Vehicle: 2008 Acura TL
The 2008 Acura TL represents a significant era in Acura’s history as the brand’s flagship luxury sedan. Built on Honda’s sophisticated global platform, the TL was renowned for blending sporty handling with the comfort and refinement expected of a premium brand.
