What is the reason for running Opti-2 at 100:1? Is it to save money by using less oil? Or is engine performance supposed to be better at 100:1 than at 50:1?
It is simply the way this oil was engineered. It is designed to run at 100-1. Smokeless, odorless, so I use in both my 2 stroke bikes and my chainsaws. I like it a lot.
