It can be quite the task to keep up with the newest lubricant specs for your fleet and/or equipment. Well a popular transmission manufacturer has a new spec and the Shell Transmission oil you were using may not meet the new spec.
Eaton Transmission Lubricant specification PS-164Rev7 is being replaced by PS-386. All major OEMs have transitioned to the new spec however, PS-164 Rev7 and PS-386 formulations can be mixed together and either fluid can be used for top offs. Eaton also has the PS-278 spec which are the only approved lubricants for the Procision transmission. Lubricants that meet PS-278 can not be used in any other Eaton transmission.
Shell Spirax S6 GME 40 meets the new spec and replaces Shell Spirax S6 GME 50 which met the PS-164 Rev7 but does not meet the new PS-386 spec. Shell Spirax S6 GME 40 was engineered for the new Eaton spec and can be used in manual transmissions as well as the Eaton Ultrashift Plus and Fuller Advantage/FR/RT series transmissions. Shell Spirax S6 GME 40 is a full synthetic formulation that provides low temperature flow, excellent oxidation resistants and excellent shear stability. In independent field testing Eaton claims an increase in fuel economy of 1.5% when using PS-386 approved formulations like Shell Spirax S6 GME 40.
The bottom line is it pays to Switch to Shell and you can count on Lynch Oil to continue “Fueling your Success.”
