Look on the Gas cap of your weedeater. It should tell you the gas to oil ratio. If its not there try looking in the manual or online.
I purchased my Toro weedeater in 2007. It uses a 50:1 gas/oil ratio.
50 to 1, using a quality full synthetic oil like Stihl Ultra. Don't skimp on oil. Use the best.
If you use Stihl genuine two stroke mix, then the ratio is 50:1 eg 500ml to 25 litres fuel
Lubricant typeHusqvarna or equiv. at 50:1 Right off the web site I use husky oil
