Long Spin Oil has thin viscosity and therefore application of this oil does not make your yoyo responsive.
This oil improves life time of your ball bearing, it also makes it spin quieter.
We recommend using Long Spin Oil with all advanced unresponsive yoyos (Replay, Wedge, Shutter etc.).
Apply 1-2 drops right into your yoyo ball-bearing. If you apply too much of Long Spin Oil, your yoyo can become responsive for a while, keep playing it and it will become unresponsive after several throws.
