Hi
 
As an ex-nurseryman, we use to also have mist sprayers that were hand
held. They worked on compressed air through an air pump. The held only 4
liters of water, (less the a gallon). The water was then propelled under
hig presure (I assume about 30-60 lbs per inch) through a fine tip that
atomised the water. I can only assume by experence there is no reason
for the same to work on oil.
