When it comes to bar oil I have generally used the brand that manufactured the saw. My reasoning was that I figured that the factory had designed it to meter out of the oil pump correctly for their saws and that has seemed true for me. However, nowadays, my saws oiling systems are adjustable so that's not much of a concern any more.
Myself I wouldn't use any type of oil that wasn't designed for chainsaws. Motor oil for example doesn't have the necessary tackifiers in it to make the oil stick to the chain while spinning even at lower RPM's.
The real problem with bar oils on a chainsaw is the the lubrication system is a total loss system. For the most part it gets slung off almost as fast as you use it. With that it is very possible that many types of motor oils will seem to work well enough but I think it's still worthwhile to use an oil designed for chainsaws.
