Also, I use non-ethanol-laced gasoline and I drain the fuel and run the engine out of gas if the machine is going to sit for a while.

I guess......getting back to your question Vash, if the bar/chain is not getting enough oil, they will wear out more quickly. Not a huge problem. And if the machine is leaking where it shouldn't, then the problem is really just oil expense, right? Also a small matter.
