Roadranger Marketing has released the results of recent fuel-economy tests revealing fuel savings of more than 1% with use of the newest generation of Roadranger Synthetic Lubricants for transmissions and axles. The tests, which compared Roadranger lubes to traditional synthetic and semi-synthetic blends, included those that were performed with two major U.S. fleets, and a third that was conducted at the Southwest Research Institute in San Antonio, Texas.

“The previous Roadranger lubricants were already producing fuel saving benefits of 2 to 4% over mineral-based
lubricants,” says Rick Muth, lubricants manager for Roadranger Marketing, “so the additional saving is a further
bonus.”

With the fleet tests, both linehaul carriers realized an average fuel economy savings of 1.029%. The Southwest
Research test generated a fuel savings of 1.112%. Each test adhered to established TMC and SAE protocols, one the SAE Type III 1526 test, the second the TMC/SAE J1321 test, and the third a modified J1376 test.

Roadranger-approved synthetics are required in Eaton’s Fuller transmissions and Dana’s Spicer axles in order to qualify for extended warranty coverage and up to 500,000-mile initial drain approvals. The lubes meet and
exceed transmission specification Eaton PS164 REV7 and axle specification Dana SHAES 256 REV C, which were introduced last year to improve low- and high-temperature operation, and provide better protection against gear wear in high-horsepower, high-torque, high-speed and heavy-load applications. Customers should look for the ‘REV7’ spec on transmission lube containers and ‘REV C’ spec on axle lube to make sure they’re getting the latest fuel-saving formulation.

Roadranger-approved full synthetic lubes are also distributed by other lube providers under many different
labels.
