Contact the F-J where you think you got the bad fuel. If you got bad fuel there, so did many others. Several years ago, September of 2007 if I remember correctly, the F-J at Carlisle, PA got a load of bad fuel and a large number of customers were adversely affected. That F-J acknowledged the bad fuel and provided assistance to those who complained and could prove they purchased fuel there at the time in question. No supplier wants to be branded as one who sells dirty fuel on purpose, word spreads quickly and they soon are forced out of business.
