The BR 600 and similar Stihl models have a 4 stroke engine that does require mixing oil and gasoline. My BR 600 is 6 years old and still running fine. I also have a Stihl KM 90 Kombi Motor which is also a 4 stroke, for use with a string trimmer, branch trimmer, adjustable angle hedge trimmer, the KM 90 is also 6 years old. Yes, these 4 stroke engines do have adjustable valves. They are much quieter operating than most or all 2 stroke machines and use less fuel, which to me is not a concern.
I use Stihl quality oil and 91 or 93 octane fuel with ethanol, no choice about ethanol here in CT.
I use Star Tron enzyme fuel treatment in all my machines 2 & 4 stroke.
I use ValvTect carbon softening additive in all my 2 stroke and Stihl 4 stroke machines.
For storage, I dump the gasoline out, add a little fresh gas mix, run the engines and dump out the gasoline. The Stihl 4 strokes have a carb with a primer bulb. I reach into the fuel tank, snag the fuel filter and while holding the fuel hose, I remove the fuel filter and pushing the primer bulb, pump all remaining fuel from the carb. Then I install a new fuel filter and store the machine for the winter.
Several reasons I chose a Stihl BR 600, it is the lightest backpack machine with the most amount of airflow. It is quiet running although I always wear hearing protection. It hangs nicely on a hanger in my cargo trailer out of my way when it isn't being used.
It reduced the time I had spent with my 86 to less than half.
I clear the sidewalks, patios, steps, etc at all of my customers places and I clean my machines and trailer interior before I put the machines back into my trailer.
I have a friend that wants to buy my BR 600 having used it several times, I may sell it and go right out and buy a new one!!!
