To better clarify... If your injection is 25mg, pull your syringe to this marking, pierce vial, inject the 25mg of air into the vial (creates positive pressure), then proceed to withdrawal the 25mg in oil.
During your first use of a new vial, some times there is negative pressure in the vial so it's best to insert a syringe, and remove the syringe from the tip and/or pull the plunger out the back of the syringe. This will allow the vial to pressurize itself to a neutral air pressure.
If you do the above, an insulin syringe will take 20-30 sec tops to fill ~30mg.
