Stiles ..We have been using Power service Diesel Kleen. Our dealers in Ohio and Florida) both recommended the booster and when pressed said that the power service was ok as was any additive that was labeled ULSD approved...however that for the Cetane booster ..power service rates oK on Cetance rating but lacks in lubricity.. Don't know how the Ford product rates in lubricity but will find out.....so much to learn
