AMSOIL OE FUEL-EFFICIENT 100% SYNTHETIC AUTOMATIC TRANSMISSION FLUID

AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is a direct-fit synthetic ATF engineered to protect modern automatic transmissions through their full OEM-recommended drain intervals. It covers a wide range of late-model specifications from GM, Ford, Toyota, Honda, BMW, Mercedes-Benz, Hyundai/Kia, and others, making it a practical single-product solution for multi-vehicle households and shops alike.

Today's automatic transmissions pack more gears, tighter tolerances, and complex valve bodies into smaller packages than ever before. That added complexity generates more heat, puts greater stress on clutch packs, and demands precise hydraulic pressure through narrow oil passageways. A transmission fluid that breaks down, thickens, or loses its friction properties under these conditions can cause sluggish shifts, shudder, varnish buildup, and ultimately a repair bill measured in thousands.

DURABLE WEAR PROTECTION FOR COMPLEX TRANSMISSIONS
AMSOIL OE Fuel-Efficient Synthetic ATF resists shearing and thermal degradation in both normal driving and severe service. It maintains a protective film on the valve body, gears, and clutch plates where metal-to-metal contact would otherwise cause premature wear. Vehicles with DEXRON VI transmissions, Toyota WS applications, and Honda DW-1 transaxles all benefit from this fluid's ability to hold its viscosity and additive integrity over the full service interval.

RESISTS VARNISH AND SLUDGE FORMATION
Heat is the primary enemy of automatic transmission fluid. When conventional or lower-quality fluids break down thermally, they leave behind varnish deposits that can stick valves and restrict oil flow through the transmission's hydraulic circuits. AMSOIL OE Synthetic ATF uses a thermally stable synthetic formulation that resists oxidation and breakdown at elevated temperatures. It also resists heat-related evaporation and viscosity loss, keeping internal components clean and properly lubricated.

RELIABLE COLD-WEATHER PERFORMANCE
Cold, thick fluid means delayed shifts, increased parasitic drag, and reduced fuel economy during warm-up. AMSOIL OE Fuel-Efficient Synthetic ATF has a Brookfield viscosity of 9,454 cP at -40°C (ASTM D2983) and a pour point of -48°C (-54°F), so it flows quickly at sub-zero temperatures. For drivers in northern climates who need fast, reliable shift response on cold mornings, this fluid delivers where conventional ATFs struggle. Its low-temperature fluidity also contributes to improved fuel efficiency during the critical warm-up period.

SMOOTH, SHUDDER-FREE SHIFTS
Torque converter lockup shudder is one of the most common complaints with modern automatic transmissions, and it is almost always a fluid issue. AMSOIL OE Synthetic ATF is formulated with friction modifiers specifically calibrated for the clutch engagement characteristics required by DEXRON VI, MERCON LV, Toyota WS, and other demanding specifications. The result is fast, consistent shift response and smooth torque converter lockup without the vibration or hesitation that worn-out or incorrect fluid can cause.

GUARDS AGAINST LEAKS
Seal conditioners in the formulation help maintain the flexibility of transmission seals and gaskets over time. As seals age, they dry out and shrink, creating leak paths that lower fluid levels and starve the transmission of protection. AMSOIL OE Synthetic ATF conditions these seals to reduce the risk of fluid leaks, which is especially relevant for higher-mileage GM 6-speed, Ford 6R80, and Toyota U660E transmissions.
