I suspect it may be castrols super twostroke with a new label? It showed up as replacement in most the stores around here. Just a guess, castrol must have a dozen twocycle products.
also FWIW, castrol grandprix is good oil for valved motors like your banshee. They doubled up on the detergency over some of there other products (like the super). I ran it last year in rotax sled motor and was impressed how clean it ran, enough I started clearing the shelf everytime I found it. $2.22 QT wallmarche.
the oil seems to run good though. about the same as the grandprix that i used before. grandprix and 2t seem to smoke a bit more than yamalube or mobil 2t, but for the price i dont care.
