Proper maintenance of the 2008 Acura CSX relies heavily on using the correct lubricants designed for its specific 2.0L K20Z2 2 engine and transmission systems. This compact sedan requires fluids that can withstand high engine speeds while providing protection during daily commutes and spirited driving. Using the right motor oil viscosity, specifically 5W-20, along with compatible antifreeze and transmission fluids, ensures the longevity of internal components and optimal fuel economy.

The 2008 Acura CSX is powered by the reliable K20Z2 2 engine, a 2.0-liter four-cylinder unit that demands precise lubrication to maintain its performance characteristics. This engine operates efficiently with a 5W-20 viscosity grade, requiring approximately 4.4 quarts of oil for a complete change including the filter. The oil pan drain plug should be torqued to 30 ft/lbs, and a new washer is recommended for the drain bolt every time the fluid is replaced. Ensuring the oil level is checked after the refill is a critical step in maintaining proper engine health.
Selecting the right oil is about more than just meeting the manufacturer’s baseline requirements; it is about providing superior protection. The Signature Series 5W-20 is particularly beneficial here, as it contains a unique chemistry designed to reduce engine wear and resist thermal breakdown better than standard oils. For owners of higher-mileage CSX models, the High-Mileage variant offers reduced sludge by 67%, helping older engines breathe easier and perform better. Complementing the oil choice is the AMSOIL Oil Filter, which provides a filtration efficiency of 99 percent at 20 microns, significantly reducing the amount of wear-causing contaminants circulating through the engine.
Transmission and Cooling System Care
The cooling system in the 2008 Acura CSX is equally critical. The radiator capacity varies depending on the specific configuration, with the MTXL7 requiring 7 quarts and the ATXL6.9 requiring 6.9 quarts of coolant. Maintaining the correct mixture is essential to prevent freezing in winter and overheating in summer. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a pre-mixed, ethylene glycol-based solution that exceeds OEM requirements and remains compatible with all coolant colors. For those who prefer a concentrated formula, the Propylene Glycol Antifreeze offers a robust alternative with extended service intervals.
Transmission health is often overlooked until a problem arises. Whether the CSX is equipped with a manual or automatic transmission, using the correct fluid is vital. For manual transmissions, the AMSOIL 5W-30 Manual Synchromesh Transmission Fluid is ideal, requiring only 3.2 pints for a refill. The drain plug torque for the manual unit is 29 ft/lbs, while the fill plug requires 33 ft/lbs, and new washers should always be used. For automatic transmissions, the AMSOIL OE Multi-Vehicle ATF or the heavy-duty Signature Series ATF ensures smooth shifting and resistance to sludge formation. The total fill for a 5-speed automatic is 6.2 quarts, with an initial fill of 3.1 quarts.
Brake Fluid and Additional Protection
Safety is paramount, and the braking system of the CSX relies on fluid that can handle the heat generated during emergency stops. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid offers superior performance compared to conventional fluids, providing stable viscosity and excellent responsiveness for ABS and traction control systems. This fluid helps prevent moisture buildup, which can lead to corrosion within the brake lines.
For seasonal storage or long periods of inactivity, protecting the engine is essential. The AMSOIL Engine Fogging Oil is a highly effective rust preventive that coats internal components, making it ideal for the CSX engine during winter storage. Additionally, for fuel system care, the AMSOIL P.i. Performance Improver helps restore fuel injectors and can improve fuel economy, ensuring the vehicle runs efficiently even after sitting for extended periods.
