The ScottOiler does not change flow rates with increasing or decreasing vacuum. The vacuum line connects to a small opened or closed float valve. When vacuum from the engine is applied to one side it opens the valve. It is either on or off. Any change in flow rate is probably do to changing ambient temperature and the resultant changing oil viscosity when temperature changes. On a cool morning you can get near zero oil flow and on a hot day it can put out too much oil.
