AMSOIL Transmission Fluid Product Recommendation Guide

Today’s automatic transmissions are increasingly complex. They are equipped with more speeds and function with complex electronics. These units are also very compact in size and driven by more horsepower than ever. Therefore they endure very hot operating temperatures and heavy loads. Using a transmission fluid that performs consistently in all conditions is more vital than ever before.

Features and Benefits of AMSOIL Signature Series Fuel-Efficient Synthetic ATF

  • Dramatically outperforms other synthetic, semi-synthetic and conventional ATF’s
  • Does not require aftermarket oil additives for proper operation
  • Impervious to extreme heat or cold
  • Protects during heavy loads and towing
  • Maximizes fuel economy due to lower friction
  • Prevents transmission “shudder”
  • Conditions seals to prevent oil leaks
  • Robust formula is capable of long service life
  • Resists deposits and sludge


AMSOIL Signature Series Fuel-Efficient Synthetic ATF is recommended for any of the following worldwide specifications:

  • Ford MERCON® LV, SP
  • GM DEXRON® VI (this spec replaces DEXRON III for older GM applications)
  • Chrysler Mopar® 68157995A (ZF 8&9 Speed ATF), SP-1V
  • Toyota WS
  • Honda DW-1, Type 3.0
  • Nissan Matic-S, Matic-W

Las Vegas Taxi Fleet Torture Test

AMSOIL ATF Severe Service LogoTo provide proof of AMSOIL Signature Series ATF’s ability to withstand severe real-world conditions, AMSOIL put their Multi-Vehicle Synthetic ATF through impartial, third party testing in a Las Vegas taxi-cab fleet. The Signature Series Multi-Vehicle Synthetic ATF formula is identical to this Signature Series Fuel-Efficient Synthetic ATF. The Multi-Vehicle formula has a thicker viscosity to meet a different category of manufacturer specifications. These taxi-cabs were operated under continuous stop and go conditions in searing temperatures for 100,000 miles. The used Signature Series ATF was then analyzed using the Aluminum Beaker Oxidation Test (ABOT). To meet the Chrysler ATF +4 standard, an ATF must resist oxidation for 500 hours in ABOT lab testing. The AMSOIL ATF not only passed the 500 hour test, it withstood another 300 hours on top of that. Again this is with used ATF with 100,000 miles of hard service.

Also shown below are the valve body and clutch plates from the taxi transmissions which illustrate AMSOIL ATF’s capacity to prevent sludge and varnish.

Clean Operation Equals Long Transmission Life

As Signature Series Fuel-Efficient ATF is able to resist oxidation, varnish and sludge formation is kept at bay. As oil ports, valve bodies and clutches are clean and free of oxidized materials, transmissions are able to function like new, with cooler operation and longer service life.

World-Class Wear Prevention

Automotive manufacturers are dictating thinner ATF viscosities than ever. GM DEXRON VI & HP, Ford MERCON LV & SP, Toyota WS, Honda DW-1, Nissan Matic-S are some of the thinnest ATF specifications that the industry has ever seen. Automakers are employing thin ATF’s to maximize fuel economy. As you can imagine, wear control and fluid film strength are vital. AMSOIL Signature Series Fuel-Efficient ATF’s robust synthetic formula offers extreme pressure additives and a stout film strength to maintain viscosity under heavy loads and extreme heat.

Extreme Temperature Performance

With a cold-pour-point of -63F, the performance of AMSOIL Signature Series Fuel-Efficient ATF is virtually unaffected by cold weather. Expect normal shifting and optimum fuel economy all winter long. In hot weather, as shown in the Las Vegas Field Test, this ATF easily withstands severe service in extreme heat.

Mixing AMSOIL ATF with Other Brands

AMSOIL Signature Series Fuel-Efficient Synthetic ATF is compatible with other brands of conventional, semi-synthetic and synthetic automatic transmission fluid. While you can safely mix AMSOIL Synthetic Oil with other brands, this will reduce the drain interval and performance capabilities of AMSOIL Synthetic ATF.

The use of any aftermarket oil additives with AMSOIL Fuel-Efficient Synthetic ATF is definitely NOT recommended.

Service Life

Normal Service: AMSOIL Signature Series Fuel-Efficient Synthetic ATF is recommended for oil change intervals as stated by the vehicle owner’s manual or as indicated by the oil life monitoring system.

Severe Service*: Change at twice the suggested OEM severe service interval.

* Severe Service: Commercial, taxi or fleet vehicles, vehicles with more than 100,000 miles (160,000 km) without prior continuous use of AMSOIL ATF, frequent towing, snow-plowing, hauling or dusty condition operation.
