I’ve always run Cool Power medium green, 15oz.  I usually change every weekend.  If you know what oil was in it before it might make sense to stick with that.  Various oils seldom mix well.  Otherwise I’d fill it, run it on the stand or a few practice laps, and change it.

93 octane pump gas, no premix.  Check your club’s rulebook, they may have a spec fuel or a certain gas station they want you to use.
