Mixing bottle accuracy
A 100ml 50/1 2 stroke oil cartridge is used to mix with 5 Litres of petrol so with the 1 Litre mixing bottle , you would only add 20ml of oil. If you add this amount to the one litre of petrol in the bottle, it does not take the combined mix up to the 50/1 line. The level hardly moves from the one Litre Mark. Am I doing something wrong or is there something not right with the bottle.
