RE: new saito 82 questions
With one exception,all the advice in this thread has been pretty good.
Saito used to recommend all synthetic oil, but several years ago they realized that engine life was enhanced for the average user when a castor oil blend was used. They wont void the warranty for people who insist on all synthetic, but they do not recommend it.
Morgan's Omega 15% is my fuel of choice in all my Saito engines, your fuel in your engines is your choice.
