Small Engines (Lawn Mowers, etc.): echo weed trimmer, echo weed trimmer, stroke oil

Question
what is the ratio of oil to gasoline for this engine?

Answer
hi keran

oil mixing ratio is  50:1 as on the bottle  if using   correct good quality 2 stroke oil

50:1 =  20 mils of 2 stroke oil to every 1.0 litre of petrol you mix
if mixing 2 litres  put in 40 mils of oil into petrol container then put in 2 liters of petrol only and give the can a shake    then fill up the tank on weedtrimmer
