I'm curious if anyone knows. Does Stihl make their own oil or do they buy it from some major oil company and then rebrand it as their own. I'm not dissing Stihl as I use their Ultra at 40:1 in my engines once broken in. Perhaps they buy a base oil from a major supplier and then add whatever ingredients that they think is best.
I think I read somewhere that Stihl oil is produced by Castrol. I do know that just because you read it somewhere (especially on the internet) doesn't make it true.
I don't know if this is true or not .......
On other forums (Chainsaw and Lawn Equip.), it has been stated that Stihl oil is packaged by at least two different companies depending on where in the world it is marketed. A published photo of a bottle of Stihl Ultra even had the Castrol logo on it. I guess the photo could have been edited but I doubt it. None of the bottles I have seen personally had the logo.
I would find it very hard to believe that Stihl actually produces or even packages any of their oils. Why should they if they can get it produced and packaged to their specs.
