It doesn't oil the OEM 20" bar sufficiently, either. (Uses ~ 1 tank of oil per 6 tanks of 2Mix.) And it's my 3rd OEM pump.And, when you upgrade a Stihl MS 361 with a 20" bar to a 24' bar you will find out that it will not oil the bar as you hoped that it would.
Someday, maybe I'll put in a 460 oiler, but for now, thinning the oil works (kinda)... and for big wood I now have a 660.
