It is crucial to note the blog’s statement on Petrozene:
“We field tested Petrozene extensively before marketing and selling the first shipments in order to ensure that we had the best possible formulation.”
Pretty clearly, this isn’t last-century Petrozene. It’s a new “formulation,” with demonstrated efficacy, from the account of the posted user.
Those unfamiliar with the oil industry will not perceive the importance of new Petrozene’s ability to quickly, inexpensively, and effectively deal with the BS&W (bottom sediment and water) problem. As alluded to in the blog, this contamination is frequent and profuse. New Petrozene’s ability to clean up BS&W from the thousands upon thousands of oil storage tanks around the world is profound.
