As soon as I kick this nasty chest cold, I'm gonna get out and get some work done. Planned on mixing some gas tomorrow, was gonna add Sea-Foam, but have never tried it in a 4-mix motor. I don't see any issues, but who knows. It's a FS-90R whacker. Thanks, JB

Regarding 4-mix engines, I haven't heard anything about using Seafoam or Sta-Bil in the gasoline before mixing with 2-cycle oil. I have heard that the 4-mix engines are sensitive to 2-cycle oils other than Stihl Ultra. I've just been mixing smaller batches of Ultra and relying on the stabilizer in the Ultra for a KM-90R and FS-130.
I've got a bunch of HP Ultra, so it'll be used. Just don't know about the Sea-Foam. I can mix enough for the trimmer and 3 saws, hoping the Foam can keep it alive a little longer, if it doesn't get used right away.
probably won't hurt anything... here is a more lengthy discussion on it's merits.
