I see no problems and only advantages to using the E0 87 octane in your 4 stroke stuff.

Just for clarification- Stihl 4 mix engines may run on 2 stoke mix, but they are still 4 stroke. So are the Shindy C4 machines. They recommend 89 or higher octane as well for all their equipment to keep it from running too hot.
