Why are Stihl engines so oily?

    I have a Stihl edger, chainsaw, and hedge trimmer. When I clean my stuff throughout the season, the Stihl equipment is always coated in burned oil. The fins on the engine are caked. My Husqvarna stuff doesn't have a thing on it but some dust. IMO Husqvarna two stroke stuff does not get the credit it deserves. The stuff is built to last. Anyone else have this problem?

    No... never had that problem with getting anything on the fins and I've got stuff 4 or 5 seasons old that have seen very heavy commercial use.

    You need to inspect your head gaskets, exhaust manifold gaskets... and probably change mix oil too.

    Stihl 2 cycle engines are "emmissions dirty" in that they by nature expel a good bit of unburnt fuel/oil mix. If you are using less than a supreme quality mix oil, less will burn, more will make it's way out, gum up, weep out of the muffler, ect...

    I have a bunch of Stihl equipment too and I've never really noticed that problem. The carb might get oily over the course of a season but no more so then any other 2 stroke I've ever used.
