In regards to chain touch ups....
My house is on a rock farm so if I can get through a full tank without rocking my chain I call it a success. My cabin is on sandy/clay soil so life is better up there.
My record is 7.5 tanks without a touchup...was cutting softwood with Stihl RS on my 550 and figured I would go as far as I could to see how long it would last. It was still very sharp at 7 tanks until I put the nose in the dirt.
