So you take one persons word and not another persons word? Have you looked up the ratings on Stihl oil V others yet? I heard from lots of guys on here that it runs dirty and dont leave much oil on the crank in fact almost dry.
People should do all the research they feel they need to. My research has shown me that Stihl Ultra at 50:1 has shown no higher rate of engine failure than any other oil. I've even talked to multiple well respected porters and while they say they don't prefer Stihl Ultra, they also say people are using it without issues.
Stihl Ultra at 40:1 can leave gummy residue and other buildup because it's not designed to run richer than 50:1, so my research says don't do that.
People are free to do their own research and make their own decisions.
