    Mix for old saws

    I'm sure this has been covered, but my search was fruitless. I have a few older saws, the richest mix listed is 16-1 in my Pioneer P25. So whats the current thinking? Are the new oils so much better I can safely run something like 30-1 or 40-1? I know a guy who runs an old Mac 10-10 with the same 50-1 s his Stihls, but he ain't all that bright, so I'm all ears on this.

    The real old beasts from the 1950s probably need a thick mix, however from my expirience, the chainsaws from 1960 on will do just fine with 40 to one.

    A quote from 2dogs

    "I firmly believe in the philosophy that safety is the number one priority in the woods. Having said that I feel that safety starts with the proper mindset and is followed closely, very closely, by the proper skillset. I think there is a tendency to offset poor skills by buying more safety gear."

    Have a 201T that doesn't run like you expected? Need a new one that's already modded and ready to go? PM me for details.

    This question has been asked 100 times. The answer is always the same. Todays 2-stroke oils are plenty sufficient at 40:1-50:1. Those old saws were specced with motor oil.

    I run all my old/vintage chainsaws on 40-1 mix and they actually run clean and cooler than they did back in the 60`s on motor oil. My oldest running saws are 1948 and newer and never worked better than now on the new oils. I recommend using premium mix oils from Stihl but any of the premium oils would be fine.

    32:1 with good oil and you dont have to worry about any 2 cycle engine! If you want to be on the safe side.

    +1, every saw below runs just fine using Stihl oil mixed at 40-1.

    Thanks guys, that's what I thought I might hear. I know the old Johnson outboards seemed to run fine at 35-1, but I was always scared to open them up. I'll stick with the Stihl and other good oils.
