I have been using Stihl oil for nearly 20 years in my MS250 and followed their 50:1 rule for their oil. I recently decided to stop using their Ultra and have decided on a semi-synthetic either from Castrol: Activ 2T (claims JASO FD but shows as FC on the official list) or Penrite semi-synthetic which claims to meet FC but not on the JASO list.
Thing is, I think Stihl are still saying that it's 50:1 for their oil and 25:1 for any other brand yet I see nowhere on this site on all the many oil discussions, where anyone has said that they are using 25:1 for anything.
Should I now be using 25:1 or is what Stihl really implying is that their oils are so much better than anyone else's that you need to use double of theirs ie is this just subtle marketing or sound advice from them?
