Are Supplements Actually Science or Just Snake Oil? In this video I'll explain why diesel engines knock, the science of diesel fuel, and the science of diesel fuel additives/supplements/treatments. I'll provide you with scientific data to help you understand the theory and economics of diesel fuel additives, so you can make your own decision about if or which additive you want to use. I focus on 4 popular All-In-One Treatments: Stanadyne Performance Formula, Hot Shot Secret Everyday Diesel Treatment, PowerService Kleen + Cetane Boost, and Archoil AR6500. I'll discuss their effects on lubricity, cetane, efficiency (MPG), performance (horsepower), injector and pump cleanliness and wear, emissions, and DPF Regenerations (Regen). And I'll provide independent test data and studies to back up my science.
