Do you fill your ***boat with fuel(s) containing an alcohol additive? Should I be concerned using oxygenated fuels containing oxyenates such as alcohol (Ethonal) or Ether (MTBE or ETBE), since it may increase: 1) corrosion of metal parts; 2) deterioration of rubber and plastic parts; 3) fuel permeation through rubber fuel lines; and 4) starting and operating difficulties. I've read that these are some of the adverse effects caused by the alcohol additives because the alcohol absorbs moisture from the air, resulting in separation of the water/alcohol from the gasoline in the fuel tank. The adverse effects of alcohol in fuels is outlined in Mercury Racing Engine's operational manual under fuel requirements. Having said that, do you know of fuels that contain fuel injector cleaner for added internal cleanliness, which is recommended for use in EFI engines, but is not oxygenated?
What do you "fill her up" with (brand of fuel: Unocal, Chevron, Shell, Mobile, etc)?
