Im jsut waiting for fedex to drop the package off at my houce. I got a build ahead of me tonite and by midnite im hoping to annoy the neibors. Would it be OK for me to use STIHL 2 stroke oil to mix? What should i put in the crankcase for oil? It should be here any minute now because its on the truck from a depot about 40 miles away!!! YEAH!!!!
