Is your fleet using the right fluids?

Mar 24, 2023

Basically, for forever, fleets have used a straight 50 weight oil in their transmissions, but Gene Jensen, Chevron Lubricants’ Lubricants Trainer, points out transmissions have evolved – a lot – over the years, and OEMs decided that they want more flexibility and transmission fluids and in the process the number of available options for each transmission type increased three fold.

Jenson joins Jason and Matt this week on CCJ's 10-44 to talk transmission fluids, gear oils and coolant for some bumper-to-bumper coverage.

Unlike other trucks in ACT Expo's Ride and Drive, Walmart did not haul its truck to last week's event but instead was able to drive the truck with Cummins new X15N natural gas engine from Indiana to Anaheim, California thanks to access to compressed natural gas stations along the way. 'That says a lot,' said Cummins manager of global regulatory affairs Tom Swenson.

Walmart is pleased with a pilot it entered with Cummins to test its new X15N natural gas engine and sees it as an ideal fit for long haul where all-electric and fuel cell fall far short on range.
