Hi I've recently borrowed a ryobi hedge trimmer but it was low on fuel so I've mixed up what I thought was 2 stroke fuel ( 1st time ever) but they now won't start I'm not mechanically minded in the slightest and I'm scared I've not mixed the fuel right. How important is it to measure the oil precisely it's t2 oil ??????any help really appreciated. Tia

Exactly what have you mixed up?
What type of fuel? How much of it?
