HONDA ATF DW1

HONDA ATF DW-1 is a genuine synthetic automatic transmission fluid specifically formulated by Honda R&D for use in a wide range of Honda and Acura vehicles equipped with their automatic transmissions (not for CVTs). It replaced the previous fluid, ATF-Z1, and is backward compatible with all applications that previously required ATF-Z1.
Key Features and Benefits
Superior Performance: Formulated with advanced additives and synthetic base oils to provide superior wear protection.
Smooth Shifting: Ensures stable and consistent operation across a wide temperature range, leading to smoother gear changes at both low and high temperatures.
Longevity: Features a low oxidation rate for improved long-term stability and extended maintenance intervals.
Component Protection: Contains special ingredients to protect transmission seals and O-rings from corrosion and excessive wear.
Fuel Economy: Has a lower viscosity for potentially improved fuel economy.
Usage and Recommendations
Compatibility: It is compatible with a wide range of Honda and Acura vehicles. It replaces the older ATF-Z1 fluid, and can be used in vehicles that previously required Z1.
Incompatibility: It is explicitly stated to not be used for CVT (Continuously Variable Transmission) applications.
Maintenance: Experts and reviewers highly recommend using genuine Honda fluid due to the specific design and sensitivity of Honda transmissions. While some aftermarket fluids claim compatibility, the OEM fluid is considered the safest and most reliable option for optimal performance and longevity.
Change Interval: Most automotive experts suggest changing the transmission fluid somewhere between 60,000 and 100,000 miles. A common method involves performing multiple "drain and fill" cycles (often referred to as the "3x3 method") to replace most of the old fluid in the system.
