A while back Tracy mentioned that he new uses 50/50 2-stroke oil and MMO(Marvel Mystery Oil).  Originally I believe that he used to use straight MMO.  I can't recall ever hearing the specific reasoning behind using MMO, and why the switch to 50/50.  I assume Tracy's thinking is based on conjecture and that is why he has not really expressed strong opinions to the group.

I considered it a non-issue as I saw no particular advantage to MMO, but now I am starting to reconsider.  My standard grade 2-stroke oil is dark and stinks like ammonia.  MMO is clear and has a pleasant smell.  Cost around here is $10/gal for generic 2-stroke oil and $18/gal for MMO.  You can pay much more for some of the "racing" 2-stroke oils (like $10/qt) so I have never tried them.  The MMO seems like a better quality product but I have no idea if it is doing what it needs to be doing when used as a fuel additive in our situation.

So Tracy, assuming that your reasons for using MMO are not based on any solid scientific finding, I would still like to hear why you decided to use it.  Other input welcome as well.  Thanks.
