    MS 261 - piston and rings after 60l/~15gal of alkylated gas + HP Ultra at 33:1

    Hello, I'm pretty new on here, used to be a lurker until recently. So I just got a new MS 261 (ver 3/carb) this spring and scrolling around during that time (including that 400-500 pages oil thread, oh god) I noticed that the veterans on this site aren't big fans of this oil. "Smells bad"...
