Cummins X15 extended drain program

Posted: March 1, 2017

Cummins is providing its OilGuard program at no charge for 2017 X15 Efficiency and Performance engines, providing the engine performance data and oil analysis needed to push oil drains up to 80,000 miles (128,000 kilometers) rather than set distances or times.

Engine data and oil samples are first drawn from test vehicles, covering at least two oil drain intervals. Those hoping to meet the 128,000-kilometer limit will need to submit the samples every 10,000 miles (16,000 kilometers), and have to use a Cummins-approved CK4 (CES20086) or FA4 (CES20087) oil such as Valvoline Premium Blue. They also need to achieve at least 6.5 miles per gallon (36 liters per 100 kilometers).

Full warranty continues along the way.

Once the tests are completed, Cummins identifies the vehicles and duty cycles eligible for longer drains. Those intervals are then set as the requirements for warranty coverage.

Cummins even provides the sample kits, prepaid mailers, and oil analysis at no charge.

“It’s really about how do we get to the best total cost of ownership,” says Mark Ulrich, director – customer support. “The tailoring part [of the program] is where we think the real value is.”

Other engines could be added to the program in the future.

For those who do not participate in OilGuard, the Premium Blue can offer oil drain intervals of up to 60,000 miles (96,000 kilometers) in a 2017 X15.
