I have tried to get a Stihl 4-Mix with no luck, even though the shops said they were not a commercial success. Seems the customers thought that since they were 4 stroke that they did not have to add oil to the gas mix. And they burned them up. Still the shops would not give them away (Stihl Co. policy?).

I just checked Stihl's site & their entire line of trimmers & brushcuttes appears to be 4-strokes given the "FS" prefix.
I bought an FS-90 years ago not even knowing it was a 4-stroke, but the operating characteristics soon caused me to investigate.
In addition to trimming around the yard/garden, I use it to clear shooting lanes in the woods. W/the 3- blade steel cutting head, it will slice though 1 1/2" pine saplings in 1 swipe. Hardwood & larger pine saplings can still be whacked off W/several swipes.
It starts easily & has never missed a beat.
