Reduced operating costs
We know total cost of operation (TCO) is important to our customers, which is why we focused on making enhancements to reliability and durability while also lowering the TCO. New for EPA 2021, the B6.7 features upgrades that allow for extended engine maintenance intervals, including longer oil drain intervals, more time between fuel filter changes and a completely maintenance-free crankcase ventilation filter. Also new for 2021, the B6.7 offers advancements in connectivity to find, prevent and resolve issues faster.
