I would assume that this is for mixing regular petrol with a 2-stroke engine oil. The mixing bottle normally has an initial level to fill with petrol which should be about 98% of the total volume. You then top up with 2-stroke oil to the final fill level. Therefore there should be two graduation levels near to the top of the bottle.
They use petrol (gas) and engine oil.
i think that we use petrol for vehicles lawn mowers etc. but we use on a daily basis too much petrol we should really cut our oil use
