Product overview
OE Fuel-Efficient ATF is the lower-viscosity fluid in the AMSOIL OE line, built for transmissions that specify a fuel-efficient automatic transmission fluid rather than a conventional multi-vehicle grade.
Synthetic base oils hold their film strength when the transmission runs hot and stay fluid when it is cold, protecting gears, bearings, and clutch material through the original equipment manufacturer's recommended drain interval.
Requirement coverage across Japanese, European, and domestic automatics
OE Fuel-Efficient ATF answers a broad set of low-viscosity requirements rather than a single manufacturer's. Japanese, European, and domestic automatics that call for a fuel-efficient fluid are all represented, which is what makes one bottle workable across a mixed household or a small shop. The specification list on this page carries the full published set, and matching the exact callout for the transmission is what decides the fit.
European and domestic entries sit alongside them, including VW and Audi G 055 005, G 055 162, and G 060 162, ZF S671 090 255, Volvo 31256774, SAAB 93 165 147, and the Shell M-1375 series. What decides the fill is whether the transmission names one of those requirements, since a fluid that covers many is still not a fluid that covers all.
The CVT boundary, including Toyota WS
This fluid is not for use in continuously variable transmissions. That limit holds even though Toyota WS appears on its requirement list, because a Toyota CVT calling for WS is a different machine from a geared automatic that calls for the same specification.
For a Toyota CVT specifying WS, Signature Series Fuel-Efficient ATF is the grade listed as suitable for that application. Reading the transmission type alongside the specification code, rather than the code on its own, is what keeps the decision straight.
Cold-start flow and low-temperature efficiency
OE Fuel-Efficient ATF stays fluid in sub-zero temperatures and resists the thickening that slows the first shifts of a cold morning. Pour point is -48°C (-54°F), Brookfield viscosity is 9,454 cP at -40°C, and the published viscosity index is 149.
Low-temperature fluidity is part of the fuel-efficiency case for a thinner fill, since a fluid that flows quickly is not fighting its own thickness during warm-up. At the hot end of the range, the flash point is 224°C (435°F).
Wear, varnish, and seals through the factory interval
In normal and severe service, OE Fuel-Efficient ATF resists wear to the valve body, gears, clutch plates, and other vital parts, and the thermally stable formulation resists the varnish that can stick valves. Seal conditioners help keep seals and gaskets from drying out and cracking, which lowers the risk of a leak.
All of that is scoped to the vehicle manufacturer's recommended drain interval, which is the schedule the OE line is built around. Transmissions calling for a conventional-viscosity fluid on that same schedule take OE Multi-Vehicle ATF at 7.5 cSt at 100°C rather than the 5.9 cSt of this grade.

Details and questions
Is OE Fuel-Efficient ATF the same as Signature Series Fuel-Efficient ATF?
Both target fuel-efficient automatic transmissions. Signature Series Fuel-Efficient ATF is the flagship line with longer guaranteed drain intervals in normal service. OE Fuel-Efficient ATF follows original equipment interval guidance.
Does OE Fuel-Efficient ATF cover Toyota WS applications?
Toyota WS is one of the specifications listed for this fluid, alongside Ford MERCON LV and SP, GM DEXRON VI, Honda DW-1, and others shown in the specifications section on this page. Confirm the match in the AMSOIL vehicle lookup guide.
What is the difference between OE Fuel-Efficient ATF and OE Multi-Vehicle ATF?
OE Fuel-Efficient ATF is the lower-viscosity fluid in the OE line at 5.9 cSt at 100°C, for transmissions that specify a fuel-efficient automatic transmission fluid. OE Multi-Vehicle ATF runs 7.5 cSt at 100°C and covers conventional multi-vehicle specifications.
How often should OE Fuel-Efficient ATF be changed?
Follow the vehicle manufacturer's recommended drain interval. The OE line is formulated to protect through the full original equipment interval.
Can OE Fuel-Efficient ATF be used in a CVT?
No. This fluid is not for use in continuously variable transmissions. Toyota WS appears on its requirement list, but a Toyota CVT calling for WS is a different machine from a geared automatic that names the same specification, and Signature Series Fuel-Efficient ATF is the grade listed for that application.
Does OE Fuel-Efficient ATF protect transmission seals?
Seal conditioners in the formula help keep seals and gaskets from drying out and cracking, which lowers the risk of a leak. The thermally stable formulation also resists the varnish that sticks valves, and it protects the valve body, gears, and clutch plates in both normal and severe service.
How does OE Fuel-Efficient ATF handle cold weather?
Synthetic base oils hold film strength when the transmission runs hot and stay fluid when it is cold, with a pour point of -48°C (-54°F). Order OE Fuel-Efficient ATF online in quart, gallon, 2.5 gallon, drum, and tote sizes.
