Have even model cars, but no Nitro. Use the bottle for adulteration of diesel. The "Schnüdel" fits nicely through the valve on the tank and the headlong scaling facilitates the determination of the mixing ratio. Finally done refueling with diesel until it clicks. Depending on the car you can place the bottle in the cup holder.
1 star deduction, because you could lose the closure and because a 2nd scale for filling the bottle would be helpful, which should then Dia not put upside down.
