Dood the opti, my EFI and your Pro XS all use the high pro green stuff. They have to know this. Could have been another ploy to help shorten the life of the lower unit. I told you how sceptical I was of that stuff when we put it in.

I know you have spent to much time dealing with this. Its fustrating but at least after this you have pretty much re done everything they had a hand in. Well that is except the fuel filter :o
