I have a featherlite weedeater Model FL21.
Could someone please tell me the oil type (I'm assuming 2 stroke) and the mixture?
Thanks,
John:)

All weed wakers or eaters are 2 stroke. Go to Lowe's or homdepot and ask for 50:1 ratio oil for a weed eater. The bottle will tell you how much 50:1 oil to mix in per gallon
