I assume the Stihl saw is old too where warranty doesn't come into play? Stihl has a warranty thing with new saws that requires using Stihl Ultra 2-cycle oil. I was told they will test for it if the saw goes for warranty work.
I agree with the other comments in that you cannot be forced to purchase a specific branded item or part, to keep your warranty intact, such as Stihl oil. They cannot force you to buy something branded by them (Stihl) that helps them make money. Generally, the public is unaware that it is illegal for a vehicle or equipment manufacturer to tie the warranty of its product to the use of the manufacturers own lubricant.
