Hi KeithP, yes no problems with running Victa (made by Valvoline) Formula V 2-stroke at 50:1, that's what the label says and that's what I've used for the past 6 years or so without an issue. I believe it is a semi-synthetic 2-stroke oil, it costs almost twice as much a a standard oil so there's no cost benefit to the 50:1 mix, but it certainly runs cleaner with less deposits and smoke than standard 2T oil at a 25:1 ratio. Highly recommended!
