I cut off the bottom of this post from above when transferred…...
Obviously the beginning of this quote was just a rehash of what has been stated several times (but also probably can't be restated enough). What I found most interesting was the recommendation to switch to a different brand of gasoline if there was a problem with "goo" from the E 10.
You would think that they would have also recommended a water separating filter too (the vented fuel cell/condensation issue is why boats have a water separating filters and not automobiles).
AND why “it might” be a larger problem than we are giving it credit for here.
For me it's going to be more important than ever to maintain a full tank of gas with the E 10 whenever my boat is not in use. Also, condensation issues would be my best guess why Yamaha and Suzuki still recommend using the E0... but that's just a guess.
One company was very vociferous on the e15 issue, flat insisting that people are too stupid to NOT use that fuel in an outboard. They have also assisted in spreading the mis-truths over the last few years about e10. I'm not saying it was an intentional campaign to mislead the public, but it sure was voiced as if it was.

That 'gunk' is apparently the result of a couple other additives that might one or all of these: benzene, xylene, and toluene. This stuff usually shows up as a result of a lower concentration of detergent additives in that brand's fuel. It also causes the same problem in non-oxygenated fuels, I have read that one several times in the last year. That's partially why Merc recommends using their brand of fuel stabilizer/cleaner in every tank. |
