Ultra is crap oil and there is plenty of evidence of this.
Stihl over all has always had poor quality oils for a premium price.
Wow, that sounds horrible. I must've somehow missed this news. Can you point me to this abundance of evidence? There must be so many failures that lawsuits were filed! Recalls all the time!
I'm interested in any evidence of residue buildup or mechanical failures you can point me to when running Stihl Ultra at 50:1. I genuinely want more data.
There's plenty, right?
