Magnum fuel Has an unknown oil content. The guy refuses to divulge the oil type or percentage. It's Magnum #1 ,#2, or #3 and that's about it.

I was at Mac Hodge's Hobby shop in Andersonville, Ga a couple years ago at a fly in. Some guy had several skids of the Magnum fuel he was selling out of the back of his trailer for $12 a case. It all went like a hot cake. I didn't buy any.
