Petro-Canada Lubricants doubles drain intervals for DLM Trucking

Petro-Canada Lubricants shares the results of a recent DURON™ Challenge with DLM Trucking, a program designed to prove the performance and value of DURON heavy duty engine oils. The results for DLM Trucking, were exceptional, proving that it was possible to double drain intervals and secure up to $70,000 in annual projected costs savings for the business.

Washington-based DLM had used the same engine oil provider for over 30 years. However, they were open to change and seeking education on the potential benefits of adopting a new engine oil. DLM met CO-Energy, a Petro-Canada Lubricants distributor and decided to take on the DURON Challenge to understand the performance and value improvements that could be made to their business.

Based on the results of the DURON Challenge, DLM converted its entire diesel engine fleet to API CK-4 approved DURON SHP 15W-40. The business has also converted all of the driveline lubricants and greases to Petro-Canada Lubricants, including TRAXON™ gear fluids and PRECISION™ greases.

The one year trial included four Kenworth trucks powered by PACCAR MX-13 and Caterpillar C-15 engines, and covered both heavy-haul and OTR (over the road) routes. DLM saw the results from the DURON Challenge almost immediately and were able to directly compare the performance of DURON against the competitor oil they had previously used for over 30 years:

“It’s been a long journey to get everyone on-board and supportive of a switch to a new oil provider, but Petro-Canada Lubricants and CO-Energy made the process feel like a real team effort. Their collaborative support and guidance at every step in the process has made this a great success,” said Larry Slavens, operations manager at DLM Trucking. “They prioritized the well-being of DLM and our operations. The results we have seen are remarkable – it doesn’t get any better than this!”

Barnaby Ngai, category portfolio manager, Petro-Canada Lubricants added, “We are thrilled to have worked with CO-Energy and DLM Trucking on this trial to demonstrate how our DURON product line can deliver tangible cost-saving results and improve overall operations. Education and support were fundamental to the success of this partnership, and we are always pleased to work with our customers in a collaborative way to get the best results possible.”

“We are excited to continue to strengthen our commitment to proving the performance of our products with the launch of the DURON Challenge, a customer-facing program designed to demonstrate the performance and value of the DURON product line to new and potential customers. Fleets are offered a free and no risk trial of DURON for use in one or more of their vehicles, along with expert support and oil analysis to demonstrate the tangible benefits DURON can deliver to their operations,” Ngai continued.

Petro-Canada Lubricants and CO-Energy developed a collaborative partnership with DLM throughout the DURON Challenge, focusing on an extensive on-site education program, which included consistent and accurate lab-based oil analysis data, and training on how to read and evaluate oil analysis data and trends in order to improve the efficiency of operations.
