I haven't used that form of Howe's, i always use the Howe's meaner power cleaner, Have tried the Power Service Diesel Clean i think its called (in a gray bottle) which also works but not as well as the Howe's. I think the Howe's one shot is more of a anti-gel/lubricator additive rather than a lubricator/injector cleaner like the Meaner Power Cleaner. I live in the Dallas TX. area so there isn't really a need for antigel component to much and i see a improvement in the truck after i use the injector cleaner. As far as the Howe's products, they are very good. I hear that many members on TDR use additive at every fill-up, for me i just use injector cleaner every few fill-ups (mainly because the Meaner power cleaner is close to $10 a bottle) and have had no injector problems ( unlike a few friends i know who own powerstrokes!) Up in Colorado where winters get cold the anti-gel component of the Howe's one shot may come in useful.
