Sthil Commercial Line Trimmers with 4 Cycle engines (still require 50:1 fuel/oil mix) - any experience

[kozal01]

My take on a 4 stroke and still have to mix gas and oil, What's the point?

Its better to have a dry sump than a tiny crankcase with a small amount of oil, especially when running the unit on its side or upside down for extended periods of time. Its actually a great idea and works great.
