Stemco Unveils DataLogger to Test Fuel Efficiency

Stemco announced that it has created a test showing fuel-efficiency gains from using its TrailerTail technology.

DataLogger provides a “precise and significantly less expensive” way to measure fuel savings from using the technology attached to the rear of trailers. 

Results can be received in four hours or less, using the measuring system developed with IOSiX, the statement from Stemco said. 

The test device plugs into a diagnostic port on the tractor to measure fuel use. The testing system was designed to isolate aerodynamic factors while minimizing other effects on fuel use, such as wind and traffic.



Bob Montgomery, a vice president at Stemco, said “many fleets really want to know that it will work for them in their specific operation, not just on a test track or in someone else’s fleet.”

Stemco also said DataLogger has been used by more than a dozen fleets to determine fuel-efficiency gains, with a savings of about 4.5% when TrailerTail is used.
