I use opti-2 in all my equipment and have never had any problems. Can I use it in the new 4mix systems? Anybody know?

I can't say for sure but you should be able to. I usually use Amsoil synthetic so I emailed Amsoil and asked them about using their oil in the Stihl 4 Mix. They said it will be fine and added that if there was a lubrication problem Amsoil would cover it.

I e-mailed Opti-2 but haven't gotten a reply yet. I am getting to old and senile to be using different mixes for different machines.
