<DIV>Ron,</DIV>

<DIV>I assume that the Morgan Pro Pattern is 100% synthetic. I believe that YS does not want you to use castor oil (or low castor content). There is some information in the manual in this regard.</DIV>

However, engine fuel is like religion to some people and they won't tolerate any contrary opinions. My fuel (religion) for 4-strokes and 2-strokes is Morgan Pro Pattern 25%.
