In my experience with lubricants, I KNOW there are many different types that need to be used for specific reasons.

What I have seen is that the manufacturer knows what is best and there are reasons they specify a specific type. So I listen to their advice. Best to do as they recommend if you ask me.

I do know from experience that Stihl Ultra two cycle oil will prevent carbon build-up - as the manufacturer claims. And that is what I use for my Stihl saws. It is not cheap!

Another thing I have learned is that automotive parts store clerks DO NOT KNOW SQUAT about what should be used with what. They are not factory engineers, yet many people will take their word over what is suggested in a factory service manual! (I'm not talking about Mercedes internet parts sites where they do have some very knowledgeable people.)

There is an internet forum [bobistheoilguy] which goes into extreme scientific detail as to what is what with various types of oil/lubricants. Might want to poke around there...
