I typically do not engage in oil wars, but a few posts ago someone mentioned the oil I use in 2 stroke gasoline engines. I have been using Amsoil Sabre at 70:1 for years and have never had an issue. I just could not bring myself to mix at 100:1, so I split the difference and mixed it at 70:1 and had good results. It probably would be OK at 100:1, but in my mind that is just not enough oil. When in doubt I err on the side of more oil, as my original post in this thread states. There are MANY good oils on the market and I am not knocking any of them. I have used the Stihl HP that Shawn likes and never had a problem with it.
Find something that works for you and stick with it.
