Stihl gas-to-oil mix?

[GIBSAW]

Hello-
For the small Stihl 011AVT chainsaw, the owner's manual is rather ambiguous about the correct gas-to-oil-ration mix. It says, "50:1/40:1"
What ratio do people on here recommend?

Pick an oil, pick a number and tune the saw to that mix.
It IS that simple.

With modern semi or full synthetic oils, designed for air cooled (not water cooled or outboard engines) either 40 or 50:1 is fine.
Personally, all I stay away from is Stihl Ultra.

Ok. Before I read your answer, I bought some Stihl Ultra HP that was recommended. Just curious as to why you don't recommend it?

Because the exhaust fumes stink, unless perfectly tuned it leaves deposits/builds carbon, its 1980's FB rated oil when every other manufacturer recommends FD and its EXPENSIVE.
Plus (not sure if available in the States?) their mid rated HP Super (red dyed) oil is FD rated and much cheaper.
