Fuel Issue

[Southern Boater]

Ah yes... never thought of ethanol that way but could be.
Also I've heard a lot about separation of ethanol but not algae.
I have heard many call the bad stuff in diesel algae but AFAIK it's not algae as algae needs sunlight?

There have been cases where ethanol mixed (gas/petrol) fuel emulsifies the inner linings of older GRP/FRP boat fuel tanks and contaminates the fuel. In this country we have been warned about it for years.
