IM READING ALL THESE THREADS ON OIL TYPES AND ENGINE TYPES THEY ARE GOOD FOR. I WAS GOING TO USE AMSOIL UNTIL I READ THAT BELRAY(HIGH QUALITY OIL) SAYS TO RUN THE BELRAY AT MANUFACTURERS RECOMMENDED RATIO. I RUN ZENOAH ENGINES ON LAWNBOY AND ABOUT TO SWITCH. IF YOU RUN A ZENOAH ON AMSOIL AT 100:1 AND IT BURNS UP WILL THEY WARRANTY IT?? CAN YOU RUN THE AMSOIL SABER AT 32:1 IF SO DESIRED WITH NO BAD EFFECTS.?? OR SHOULD I USE THE BELRAY OR ANOTHER TYPE ? THE ZENOAH ENGINES RUN GOOD AT 32:1 OIL CONTENT. ALL OPINIONS AND EXPERIENCES WELCOME ON THIS. THE BOTTOM LINE IS I DO NOT WANT TO REDUCE THE OIL CONTENT BELOW 32:1 ,IF I USE AMSOIL SABER AT 32:1 -- CAN IT WORK??? WILL IT CAUSE PROBLEMS. IS AMSOIL SO MUCH BETTER THEN BELRAY THAT YOU CAN RUN IT AT 100:1 AND BELRAY RUN AT MANU SPEC RATIO. AND DO THE MANUFACTURERS OF THE ENGINE AGREE WITH THE PROTECTION AVAILABLE AT 100:1 WITH THE SABER. THANKS FOR HELP FROM YOU ALL.
