Re: can i?
Although somewhat fearful at first I have been convinced to use Opti-2 oil mixed at 100-1. Works fine and burns clean.
What convinced me was talking to two different construction equipment rental yards here locally. They both send out gas mixed with Opti-2 at 100-1 with every two cycle motored piece of equipment they rent out. Neither had had and oil related engine issues in over ten years of use.
Their reasoning for using it was every different brand of power product that had a two stroke motor had a different recommended oil-gas mix. That was unrealistic for them to keep straight what device needed what mix so they chose Opti-2 and use it in everything.
Good enough for that kind of service good enough for me.
