as i posted in #12, i'll mix my first batch of purple after i burn one more gallon of break-in penz air cooled...andy and others have given good reports (i can use the other oils in my chainsaw)...it would be interesting to see a new thread on 'quicksilver rejuvenate', which is supposed to meet JASO-FD...a local mercury marine sales/service shop never even heard of it (they sell yamalube)...
