Chuckles, what do you think of the reports of overt corrosion in aluminum alloy float bowls? I have seen photos of this and the green stuff. They aren’t making it up, but I have had hard time believing that a low percentage of ethanol is doing that. A higher percentage, yes. What do you think? Are they putting in another additive that’s doing it?

[chuckles]

I would have to see for myself. Maybe Chinese alloy? Who knows. Gas without ethanol is nasty stuff. Some is higher sulfur than others, has more benzene than normal, etc. I also know that normal gas also will get water condensate in a bowl and have rusty crust in it after sitting for a season. Green, I don't know.

If it is a 2 cycle like an outboard, it could be the type and amount of oil used. But I wouldn't think it would corrode the metal, but just leave a slime. I would have to know more details for even a guess.
