Oil ratio

I’m running a 40:1 trufuel in my 1980 sachs prima that takes 50:1 from what the gas tank says, someone told me that the 40:1 would be better but I don’t know that for a fact, if this is true let me know I’m new to this thanks

Re: Oil ratio

It will not hurt it. Mix your own, way cheaper, 40:1 to 50:1 is fine with the quality of today's oils.

1:50 is fine as stephen said. If you want to up your game put in this stuff and you can go 1:100. No blue smoke anymore too..
