    What fuel/oil mixture ratio should i use for my 31cc Ryobi weed wackers?

    At the moment i have been using 40:1. Is that ok?

    32 to 1 is what I found online. I use 24 to 1 in mine because that's what my chain saw uses too. 40 to 1 may be a little light on the oil unless your using something like Opti-2.
