Effective April 1st of 2006, Eaton Transmission Division authorized a change to a “next generation” lubricant specification. It’s now required for all extended transmission warranty coverage and 500,000 mile drain intervals. Eaton’s Roadranger system partner, Dana Corporation, is also making similar changes to the drive axle lubricant specification that will be effective in the 1st quarter of 2007.

What’s driving the movement to synthetics?
Since 1990, there have been industry increases in engine horse power, torque, component design changes, increases in component operating temperatures, and changing customer requirements…all requiring the need for significantly improved gear surface and bearing protection.

What does this mean to you?
Due to advancements in lubricant base stocks and additive technology Roadranger lube can now offer you superior component thermal protection that provides enhanced high temperature component protection and greater low temperature lubricant performance. This means improved cold weather flow in all driveline products and specifically, improved shiftability in transmissions. Higher performing, more efficient lubricants mean increases in fuel economy* and outstanding extended drain protection for virtually all brand transmissions and axles. Full synthetic Roadranger lubricants also run cleaner which helps reduce contaminants and provide longer seal life.

How do I identify approved lubricants?
The new generation transmission fluids indicate on the label that they meet the new Eaton Specification PS-164 Rev 7.  The new generation axle fluid, when available in 2007 will indicate on the label that they meet the Dana Specification SHAES 256 Rev C… and yes; the old and new generation fluids are completely compatible.

Is it available at all OEM’s? 
Yes, Roadranger full synthetic Transmission and Axle lubricants are available as standard fill at most OEM’s.
