Most people use the bottle to 2-stroke oil to mix diesel.
There are, however, a big problem, the tube is easy to get too thin for the 2-stroke oil neat and especially fast in the tank.
One has since squeezing 3-4 times, and then wait again until the bottle when diverge air sucked.
I had the bottle on a holiday trip there and would almost desperate to it, even at home at my local gas station, it takes far too long and it's too cumbersome because to press 3-4 times until the bottle is empty times.
For the ride home from the holidays (1 fuel stop at the resort and one the way) I have filled me an empty mouthwash bottle with the remaining oil from the canister. When refueling, I just filled with this bottle and it went real fix. Natärlich I'm here no mark but that does not bother.
For the future, I'm going to get normal 250ml bottles and fill them.
Negative is the small rubber plug, the risk of losing is also large, so that the bottle is then no plugs in Kommer room.
For the modeler bottle is certainly better suited !!
