I am on the last bottle of fppf and have been happy with fppf but was thinking of trying primrose due to comments read here by George Morrison and others. Anyone have experience switching to either ?

only switch I have made if from Howe's to fppf .... so far as mileage or performance change, haven't felt or otherwise noticed any ... on the positive side, have noticed that their is no rust in my OEM fuel filters since changing to fppf, with Howe's they were badly rusted
