Food Grade Propylene Glycol, Vegetable Glycerine (which may be thicker than your original oil?), Distilled water.1ml thinning to 5ml oil should be a good mix. If you need more to suite your needs you can use as much or as little as you want. Your gonna need a more powerful vape pen than the ones you buy at the gas station. One that you can adjust the voltage going in and try to make sure it has a dual coil. Good Luck
