I have been looking around for some different oil mix to use. We have been using Stihl but I dont like buying it in the little bottles. We finally talked 2 of our local Stihl dealers into getting us some gallon jugs but the cost is pretty high. So I have been searching for a better (cheaper) alternative. I have found Echo gallons a bit cheaper, but no by much. This past week I was a our local Fleet Farm and saw several different 2 stroke oils for sale that are quite a bit cheaper than Stihl or Echo and I am wondering if they are any good. Of coarse now I for got the exact brands that I saw, but I know they were made my major oil companies like Mobil and Castol I think. The all say they work with chainsaws and one of them even mentioned Stihl on the label. So my question to you chainsaw gurus here is: Are these other brands any good or are they junk? We only run Stihl saws and blowers and I dont really want to wreck a saw to save a few bucks. Please enlighten me. Thanks.
