The 1998 Acura CL is equipped with a 2.3-liter four-cylinder engine, specifically the F23A1 engine code. This engine has a total oil capacity of 4.5 quarts when including the filter change. It is important to ensure the oil level is checked after the refill to maintain optimal lubrication. For those owners who prefer a different manufacturer’s filter or a more budget-friendly option, the WIX Oil Filter (51334-EA) serves as an excellent alternative to the AMSOIL branded Oil Filter, which is the EA15K20-EA.
Beyond the engine, the cooling system requires 7.4 quarts of AMSOIL Passenger Car & Light Truck Antifreeze & Coolant. AMSOIL also offers the AMSOIL Propylene Glycol Antifreeze and Engine Coolant for this capacity, a concentrated formula that requires mixing with distilled water, offering a biodegradable option that provides protection up to 150,000 miles or 5 years.
Transmission and Differential Lubrication
The lubrication requirements for the transmission depend on whether the 1998 Acura CL is equipped with an automatic or manual gearbox. For the automatic transmission, specifically the 4-speed model identified by codes M7ZA and B6VA, the total fill capacity varies slightly between 6.4 and 7.6 quarts, with an initial fill of approximately 2.6 quarts. To maintain peak performance, the AMSOIL AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid is recommended for its ability to withstand the rigors of heavy towing and elevated temperatures. For a more economical option that still offers full synthetic protection, the AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid provides a stable shifting experience and sludge resistance.
Owners of the manual transmission version, indicated by the S2A8 5-speed code and GLS43 specification, should use the AMSOIL 5W-30 Manual Synchromesh Transmission Fluid. This fluid is formulated for maximum protection in synchromesh transmissions, reducing friction and heat while resisting oxidation and acid buildup. It is ideal for ensuring smooth shifting in cold weather and maximizing fuel economy for this specific transmission setup.
Brake Fluid and Seasonal Maintenance
Maintaining the braking system is equally important for safety. The 1998 Acura CL requires a brake fluid that meets Acura Heavy Duty DOT 3 specifications. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is the recommended product, offering superior performance in ABS and traction-control systems by maintaining a stable viscosity across extreme temperature ranges. This ensures consistent pedal feel and reliable stopping power regardless of driving conditions.
For seasonal storage, AMSOIL offers several additives to protect the vehicle when it is not in use. The AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, fighting ethanol corrosion and preventing varnish buildup. For long-term engine protection during storage, the AMSOIL Engine Fogging Oil provides a rust preventive coating for internal components, ensuring the engine starts smoothly when it is taken out of the garage again.
