Clear & Bright is a term that describes the visual quality of Diesel fuel.
Over the years I have sampled many Generator fuel tanks. Probably over 200 samples done and I have found contamination – particulate, water and bacteria – in all of those tanks. I am referring to fuel contamination that builds up over the period of a year.
Engineers ask me why those tanks develop sludge and particulate over a year even though they are running the Generators every month. I have an answer but I found an article that explains it better than I could in a million years. http://www.wpowerproducts.com/news/white-papers-articles/fuel-polishing-and-cleaning-secrets-to-diesel-generator-longevity-and-performance
