How a major recycler maximizes uptime and minimizes operating costs of its natural gas fleet

TFC’s trucks are under tremendous pressure, hauling 10,000 to 12,000 tons of recyclables a month under severe-duty, stop-and-start conditions and in an area where summer temperatures can exceed 100o Fahrenheit


In an effort to get the longest service life possible out of its 40 CNG trucks, TFC switched to Delo® 400 NG SAE 15W-40 – formulated specifically for natural gas engines – along with Delo ELC extended life coolant.


Since they switched over to the Delo family of products, they haven’t experienced any engine failures related to lubricants and were able to run a test vehicle 1,000 hours without an oil change; finding that the engine was still as clean “as if it were new” (TFC normally changes oil every 400 hours).


Watch our video to hear TFC’s results with these products, directly from the mouths of management. The video also features a tear-down of a Cummins ISL-G CNG engine. See what kind of condition the engine is in after 8,000 hours on Delo products.
