Belief in diesel fuel additives is a religion based on faith. You simply have to choose to believe and ignore all criticism, all opposing points of view, the truck owner's manual. printed recommendations published by the engine manufacturer, anecdotal evidence offered by others, and facts.
Have any of you who practice this religion ever noticed that commercial truck fleets, company fleets who own as many as 100, even 200 trucks, trucks costing $120k or more, all of them fueling every single day and running more than 100k miles each and every year, trucks with 500k mile engine warranties, and all of them required to provide at least 500k miles of reliable service to the initial owner, don't use any fuel additives? Ever wonder why?
