So, my engine's manufacturer (Mercury) recommends that I not use ethanol or methanol blends in my boat. Anyone know which brands are most likely to be safe? When I ask the person behind the counter at the local gas n' go, I get a blank stare. I used to try to stick with Texaco, but now they've mostly left the area after selling to shell, and I thought I read somewhere that Shell was one of the bad ones.
