Anybody here have experience with this? I think this is the system Costco is starting to install at some pumps. The detergent is appears to be PEA plus Mannich condensate anime with a lubricant. Additech is an Afton company and Afton is one of the biggies in fuel and lube OEM additives, so "it must be good" right.
