Ethanol

Well my testing of 93 octane pump mix with ethonal is almost
complete. I mixed this batch up back in 2013 in Oct I think if
not Sept.
I have been keeping a eye on it for separation etc. Storing in
plastic fuel can which is suppose to be way worse then keeping
it stored in metal cans. None separation never.
I also would take some out and leave in open qt glass jar. Never
any separation this way either.
So far I have burned 2 tanks through a leaf blower at WOT at
30mins to 40mins at a time. Using this old mix instead of my
freah mix setting here. Just so I could test and see some more.
All in all I am 100% happy they way Klotz KL-200 has stayed
mixed the entire time. Ethanol was a non issue using this mix.

Only thing I wonder is how bad the gas degraded during all that
time.

Thanks for the long term data on this. Interesting to see that
it hasn't separated after more than a year. You may be right
about the fuel itself though, I'd imagine it has lost some of
the VOC and is less potent. Wonder where the octane number is
at now? Good idea and test! ;D

My experience using Pennzoil air cooled two stroke oil with pump
gasoline (E10) is much like cut4fun's. But we live only some
10-12 miles apart. So the gasoline may be pretty much the same?
In some areas of the USA, two stroke mix doesn't last well at
all. Something is different about the gasoline in some parts of
the country?

I have no idea? I'd assume most if not all your guys gas comes
from the same supplier. I know around here almost all places,
regardless of brand, comes from one or two suppliers. Never had
any issue with separation here either but I don't generally
leave any that would have the chance. Leftover mix from the 6hp
Johnson motor we have seems ok the following spring each year
but we dump that into the other boat with carburated 4.3 OMC and
it doesn't mind.

I tried to get some straight info from a couple of gasoline
companies several years ago. My take aways were: 1) gasoline is
blended to meet automobile specifications, not small engines;
and, 2) there are a lot of different additives in most gasoline,
to meet those specifications, or emissions requirements.
Their comments suggested that some of these additives may change
over time, even if the gasoline itself did not. Might be part
of the reason why 'old gas' was not as big of a deal in the
1960's.
The other was the change in the carbs. My Toro snow thrower
with the 2-cycle Tecumseh engine would start on the first or
second pull after sitting for 7 or 8 months, with just a little
Stabil in the mix. But it did not even have an air filter on
the carb! Modern saw carbs are much more fussy.
So, even if you did not get visible separation, there could
still be stuff that might gunk up a carb. I have had some
friend's saws that would not start. After they admitted that
the fuel was 4 months old, we dumped it out, put in fresh,
pulled 10+/- times to clear the lines, and vrooom.

I had no problems starting anything, saws blowers etc with the
2013 mix. Even left it in one saw since 2013 to make test cuts
from time to time. No troubles.

Saving info from echo on Ethanol gas. I am seeing issues in
folks that store their mix wrong and in eq setting for long
periods drawing in moisture.
