There were no strato saws in the 80’s either, though. Running an 028 or 046 at 50:1 is similar to running an ms261 at 80:1I think it's very regional and dont give a true account of what oil is used. Depends on si much like availability, price, how people on youtube influence others (not that anyone is brainwashed of course) and how good the product marketing is. Take Stihl top oil for instance, they use it in their moto mix fuel, it cant be a rubbish oil like some make out but only rated jaso FB oh this may cause a stir but going back years in fact early 80's all we used was oregon two stroke oil and never any problems at 50-1
