24to1 or 3oz to 1 gal but my self dont like mixing that much because todays gas losses its octane quick..I mix 1 1/4 or 1 1/3 oz oil to 18 oz of gas,and I drain weed eater after done..WHY? because I bought new weedeater and left gas in it and the gas or mixster eat my hose in 2 months...

Use a 25:1 mix of petrol to a good quality semi synthetic two stroke oil such as Oregon and you'll be fine.
