DLM Trucking doubles oil drain intervals thanks to Petro-Canada Lubricants

Petro-Canada Lubricants has shared 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 state-based DLM had used the same engine oil provider for more than 30 years. However, it was open to change and seeking education on the potential benefits of adopting a new engine oil. DLM met Petro-Canada Lubricants distributor CO-Energy and decided to take on the DURON Challenge to understand the performance and value improvements that could be made to its 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 was able to directly compare the performance of DURON against the competitor oil it had previously used:

•Drain intervals doubled from 20,000 miles to 40,000 miles.

•Essentially no oil consumption in the first 20,000 miles using DURON. With DLM’s previous supplier, one gallon of oil was consumed within the first 12,000 to 14,000 miles.

•The engine oil’s Base Number (BN) at 20,000 miles was 2.5 times better with DURON than it had been with DLM’s previous supplier.

“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.

Barnaby Ngai, category portfolio manager, Petro-Canada Lubricants, said, “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.”

Petro-Canada Lubricants and CO-Energy developed a collaborative partnership with DLM throughout the DURON Challenge, focusing on an 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 efficiency of operations.
