YoYoFactory Long Spin Performance Oil is a thin lube for yoyo bearings. While thicker lube will make a yoyo very responsive, the purpose of this thin lube is to prolong the life of your bearings while still allowing for unresponsive play. Occasionally applying a single drop of lube to a large (size C) clean bearing will help the bearing last longer. If you find your bearing is making a lot of noise this thin lube may also quiet it down. All that being said, too much of this lube on any bearing will make it play responsive, and applying this lube to smaller bearings (Size A or Size B) will usually make them responsive, even if only a single drop is used. (If you accidentally add too much lube to a bearing the lube will wear out over time and before long the yoyo should play unresponsive again.) On the other hand, this lube can also be used to increase spin times on offstring yoyos and looping yoyos, assuming the response system is aggressive enough that the yoyo does not need a thicker lube.
