Question about Ryobi 30cc 17" String Trimmer Zrry30530 Wcurve Shaft
the ratio of oil to petrol you should use is 50:1 ( that is 20 mils of hi quality 2 stroke oil per 1.0 litre of petrol you mix ) using hi quality sthil / husqvarna 2 stroke oil
1000 divided by 50 = 20 mils of oil per 1.0 litre of petrol
NOTE if you do not have any hi quality 2 stroke but some from your local garage ( that you may use in say a scooter for example use 40 mils of oil per litre it is richer
this will do the job
cheers hope it helps
