Bottle for mixing 2 stroke engine fuel and oil.
You can see the right ratio by looking at the bottle,
without measure anything before.

During the research I found out that it's taking a lot of time and many measuring equipment.

There are 2 containers inside the bottle, the bigger for the fuel and the smaller for the oil.
when you pour it, the two mix together, creating the perfect fuel for your 2 stork engine.
