AMSOIL SIGNATURE SERIES FUEL-EFFICIENT 100% SYNTHETIC AUTOMATIC TRANSMISSION FLUID

AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid delivers long-lasting thermal protection and smooth shifting performance for trucks, SUVs and commercial vehicles operating in severe-service conditions. Proven over 180,000 miles in a punishing Las Vegas taxi fleet trial, this fluid retained 54% of its original oxidation inhibitors and kept transmission internals virtually free of sludge, deposits and wear.

Modern automatic transmissions pack more gears, more clutch packs and narrower oil passages into smaller housings, all while handling higher horsepower and torque loads than previous generations. Towing a heavy trailer through summer heat or grinding through stop-and-go traffic pushes fluid temperatures well beyond what conventional ATF can handle. When the fluid breaks down, shift quality deteriorates, deposits form in the valve body, and component wear accelerates.

RESERVE PROTECTION AGAINST HEAT AFTER 180,000 MILES
In the industry-standard Aluminum Beaker Oxidation Test (ABOT), Signature Series Synthetic ATF that had been used for 180,000 severe-service miles in Las Vegas taxi cabs still resisted oxidation longer than new Chrysler ATF+4 fluid is required to last. The transmission's valve body was clean and virtually sludge-free. Clutch plates showed only trace discoloration and earned a rating of "good," the highest possible score for deterioration and wear. That kind of reserve capacity means the fluid is still doing its job long after conventional fluids have broken down.

OUTSTANDING WEAR PROTECTION UNDER SEVERE LOADS
Varying speeds and loads create torque multiplication that puts extreme stress on gears and bearings. Signature Series Synthetic ATF is formulated with high film strength and premium anti-wear, extreme-pressure additives to prevent metal-to-metal contact. In the FZG Gear Wear Test, fluid used for 180,000 severe-service miles achieved a "Pass" at stage 12, the highest stage. Those results exceeded both the Ford MERCON V and Chrysler ATF+4 specifications for new fluid. For anyone pulling a fifth-wheel with a Ram 3500 or running a Ford F-350 with the 10R140 transmission, that wear margin translates directly to longer transmission life.

FRICTION DURABILITY FOR SMOOTH, CONSISTENT SHIFTS
Torque converter shudder and erratic shifting are common complaints in high-mileage trucks and SUVs. The root cause is often degraded friction modifier chemistry in the transmission fluid. AMSOIL formulated Signature Series Synthetic ATF with friction modifiers that deliver strong clutch-holding capacity (static friction), reliable torque transfer (dynamic friction) and effective anti-shudder properties in slipping torque converter clutches. After 180,000 miles of severe service, fluid analysis revealed nearly identical friction properties compared to new fluid. Owners of GM 6L80 and 6L90 transmissions, Ford 6R80 and 10R80 units, and Chrysler 845RE and 8HP transmissions benefit from shift quality that holds up over the full drain interval.

COLD-TEMPERATURE FLUIDITY
Cold, thick ATF slows shift response, increases fuel consumption and puts unnecessary strain on the pump during warm-up. Signature Series Fuel-Efficient Synthetic ATF is wax-free with a pour point of -65°C (-85°F) and a Brookfield viscosity of 7,676 cP at -40°C. It flows immediately on cold starts, improving shift response, energy efficiency and warm-up times in cold-climate applications. For trucks and SUVs operating in northern winters, this fluid reaches critical components faster than conventional transmission fluids.

SPECIFICATIONS AND COMPATIBILITY
Signature Series Fuel-Efficient Synthetic ATF (ATL) covers a broad range of OEM specifications including Ford MERCON LV and MERCON SP, GM DEXRON HP and DEXRON VI, Chrysler MOPAR 68157995AA and SP-IV, Honda/Acura DW-1, Hyundai/Kia SP-IV and SPH-IV, Toyota WS, BMW 83 22 0 142 516, Mercedes-Benz 236.12, 236.14 and 236.15, ZF LifeguardFluid 8 and LifeguardFluid 9, Mazda ATF FZ, Nissan Matic-S and Matic-W, Volvo 31256774, VW/Audi G 055 005 and G 055 162, and many others. It is backward compatible and replaces DEXRON III fluids in older GM automatic transmissions (DEXRON VI supersedes the obsolete DEXRON III specification). It is also suitable for Toyota CVT applications calling for the Toyota WS specification.

AMSOIL also offers Signature Series Multi-Vehicle Synthetic ATF (ATF) for transmissions requiring Allison TES-389, Ford MERCON V, Chrysler ATF+4, Honda ATF-Z1, Toyota Type T-IV and related specifications.

SERVICE LIFE
Normal Service: Follow the vehicle manufacturer's normal-service drain interval. Severe Service: Double the vehicle manufacturer's severe-service drain interval in passenger cars and light trucks. Outside the U.S. and Canada, change at the vehicle manufacturer's recommended drain interval.
