Eaton has revised its line of synthetic lubricants and added new synthetic transmission fluid specifications, Eaton PS-386 and Eaton PS-278. The first specification is for later-model Eaton heavy-duty manual and automated transmissions, and the latter is for Eaton medium-duty Procision transmissions.

The new Eaton PS-386 specification replaces the decade-old PS-164rev7 spec and is backward compatible and mandatory for Eaton Fuller Advantage Series (FAS) Series transmissions, high torque models, all automated units, and for extended protection plans. Initial tests have demonstrated fuel economy improvements of 1.5% in non-Fuller Advantage Series transmissions.

Oils meeting PS-164rev7 should be phased out by the end of 2016, and Eaton says that it is acceptable to mix the old and new lubricants in the meantime.

The new Eaton PS-278 lube has been formulated for the medium-duty Eaton Procision transmissions and their wet dual-clutch design. It is not intended for any other Eaton transmission. PS-278, unlike PS-386, is not replacing an older specification.

Meanwhile, the entire lubricant line now carries the Eaton name, and package labels have been redesigned to easily identify the current generation of products and specifications.

A new colorful labeling system that features gold-and-yellow logos identifying all PS-386 lubricants and light green logos identify PS-278 containers. Eaton also is making light green dip stick tags available for Procision transmissions.

Eaton-branded lubricants now include three axle fluids, Eaton 75W-90 Synthetic Gear Lubricant, Eaton 80W-140 Synthetic Gear Lubricant and Eaton FE 75W-90 Fuel Efficient Synthetic Gear Lubricant (all API GL-5) and a multi-purpose grease, Eaton Multipurpose Grease EP-2 (lithium complex) and the two new above mentioned transmission fluids.
