Now I know that in practice it doesn?t matter a jot but every time I mix up
some two-stroke fuel I agonise (very slightly) over whether it?s one part
oil added to 50 parts petrol or one part oil *in* 50 parts petrol/oil mix
(hence one part oil added to 49 parts of petrol)

So, does a 1:50 mixture equal 2% oil in petrol or 1.96%?

In practice how are you measuring it anyway?
