Hello cardsfan300! First, I really appreciate the comment and we're so happy people are loving the BiiP! That's a pretty thin liquid. I think even back when I started, I was using 70/30 PG/VG. The Z-Coils have been tested from 50/50 to 30/70 PG/VG. Best bet is to give it a shot and see how it behaves. Remember, I have a set of tutorial videos for the BiiP and other Platform products. You can access them by scanning the QR code that comes in the package, or by visiting the Innokin.com website directly. I talk about flooding in the Troubleshooting video and some potential solutions should you experience it.
