Ensuring Proper Engine Oil Capacities and Grades
The K24Z2 engine in your 2008 Honda Accord is designed to run on 5W-20 viscosity motor oil. For the oil capacity, the system holds 4.2 quarts without a filter change, but when changing the filter, the total fill requires 4.4 quarts. It is crucial to check the oil level after refilling to ensure the correct amount has been added. The torque specification for the oil drain plug is 29 ft/lbs, which should be followed during service to prevent leaks or stripped threads. Using the recommended oil grade helps maintain the delicate balance between lubrication and fuel economy that Honda engineered into this powerplant.
AMSOIL Signature Series 5W-20 100% Synthetic Motor Oil is a top-tier choice for those seeking maximum protection, offering 75% more engine protection against horsepower loss and wear. It can extend intervals up to 25,000 miles. For owners who prefer a balance of performance and value, the Extended-Life 5W-20 provides 37% more cleaning power and guarantees protection for 20,000 miles. The OE 5W-20 is an excellent option that outperforms conventional oils and helps prevent low-speed pre-ignition (LSPI). For higher-mileage Accords, the High-Mileage 5W-20 formula features enhanced detergents and anti-wear additives to reduce sludge by 67%, helping the engine run smoother and last longer.
Transmission and Manual Fluid Requirements
The 2008 Honda Accord is available with both automatic and manual transmissions, each requiring specific fluid types and capacities. For the automatic transmission, whether it is the B97A, M91A, or B90A variant, the total fill capacity is 6.9 quarts, with an initial fill of 2.6 quarts. These transmissions benefit greatly from AMSOIL’s synthetic options. The Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid is engineered to withstand the rigors of towing and high temperatures, ensuring fluidity even in sub-zero conditions. The OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid is another robust choice that resists sludge formation and promotes smooth shifting while guarding against leaks.
If your Accord is equipped with the 5-speed manual transmission (88E5), it requires a specific fluid. The capacity for this unit is 3.8 pints. AMSOIL 5W-30 Manual Synchromesh Transmission Fluid is formulated to reduce friction, heat, and wear in these transmissions. It improves cold-weather shifting performance and maximizes fuel economy, making it an ideal replacement for the factory-specified Honda Manual Transmission Fluid.
Coolant and Brake Fluid Specifications
Proper cooling system maintenance is essential for the longevity of the engine. The Propylene Glycol Antifreeze and Engine Coolant capacity depends on the transmission type; vehicles with the MTXL6 transmission require 6.4 quarts, while those with the ATXL6 transmission hold 6.3 quarts. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a ready-to-use 50/50 pre-mix that protects all cooling system metals, gaskets, and hoses. It is free from phosphates, nitrates, and silicates, ensuring compatibility with all vehicle components. For those who prefer a concentrated solution, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers a longer service life, protecting against corrosion and erosion for up to 150,000 miles or 5 years.
Brake fluid plays a critical role in vehicle safety. The 2008 Honda Accord recommends a heavy-duty DOT 3 fluid. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid meets or exceeds these requirements, providing excellent responsiveness for ABS and traction control systems. Its stable viscosity ensures consistent braking performance across a wide temperature range, giving drivers confidence in the vehicle’s stopping power.
Films and Air Filtration
Filtering contaminants from the engine is just as important as the oil itself. The AMSOIL Oil Filter is designed with high-efficiency media that captures 99% of particles at 20 microns, allowing for lower restriction and better lubrication of engine parts. It also offers greater capacity for contaminants compared to many competing filters. For the air intake, the WIX Air Filter utilizes premium media that improves upon OEM standards, ensuring clean air reaches the combustion chambers for optimal performance and fuel efficiency. The WIX Oil Filter serves as another excellent option for those who prefer a well-known aftermarket brand, offering significant improvements over standard equipment filters.
Additional Maintenance Products
To keep your Honda Accord in peak condition, AMSOIL offers a range of additional products. The AMSOIL P.i.® Performance Improver Gasoline Additive is designed to restore fuel injectors to 100% flow rate, which can recover up to 14% of lost horsepower and improve fuel economy. This additive is particularly beneficial for engines with direct injection systems. For seasonal storage, the AMSOIL Gasoline Stabilizer keeps fuel fresh for up to 12 months, preventing varnish and gum buildup that can clog fuel systems. The AMSOIL Engine Fogging Oil provides excellent rust prevention for internal components during extended periods of inactivity.
