two stroke oil ratio is 100:1
So for every litre of petrol you need 10mils of oil

Get yourself one of those little spirit bottles that they have on planes (50ml) and put that into your 5L can of fresh new petrol. Make life easy on yourself.

A baby's bottle can be great for measuring it out about 250-300ml as well.
