I cut my VG when I get it with 10% distilled water. By itself. Nothing figured but VG and water. Mixes are PG35/VG65 and PG30/VG70. I run them throught carts, clearos, bcc's, and dct's. No problem. I get 2-3 weeks or more life out of all of them with all my blends regardless of what's in them. I use no alcohol of any sort ever. That's me before all you start hollering. I'm not mixing for PG sensitive either. I'm after vapor.
