Marvels Mystery Oil MMO Formulation
I just got back from the Stuart, FL airshow. Other radial drivers are stating that MMO has gone through a formulation change under new management and that it no longer performs as well. They say Amsoil 2 Stroke Synthetic is now preferred by crop dusters running radial engines.
So, does anyone else have information to confirm or debunk this?
Thanks
