but not positive that most all of the diesel fuel in metro Atlanta flows through the same pipeline owned by Colonial Pipeline. That pipeline is the major one of two pipelines that serve Atlanta. It's the one that has had two separate issues (explosions) recently affecting gas and diesel prices and availability across parts of the Southeast. See link below.
I believe the local fuel distributors add their additives at the local distribution points. Who knows what kind of quality control they follow or how good the actual execution of that quality control plan is. I tend to believe it is probably pretty good, maybe even automated and excellent.
I have no problem using Diesel-Kleen to ensure at my micro-level of use I am getting the lubricity and cetane bumps I want. Never experienced any issues I would attribute to Diesel-Kleen. I don't necessarily hit every tankful with Diesel-Kleen as sometimes it s just not easy (traveling away from home...).
