The use of PowerSpec is supported in North America only. For engines equipped with a Diesel Particulate Filter, Ultra Low Sulfur Diesel Fuel is required. Failure to do so can permanently damage engine and aftertreatment systems within a short period of time. This damage could cause the engine to become inoperable and affect the warranty coverage on the engine.
