When I/we first started using the eGo-C/CE-5 system, I went with mostly VG juices because I was concerned about PG. I don't know why I was concerned, but I was. Recently, my wife and I discovered a local store that carried different juices. Though they didn't list whether they were VG or PG, they were much thinner and worked far better in our e-cigs without much plugging up. I assume they were more, or all, PG. We bought most of our products from My Freedom Smokes and ordered the extra VG. Now that we are using the "thinner" juices, our VG juices has continued the "plugging" process and we have to clean our atomizers more often. We have an unflavored nicotine that we use to step up our lower nicotine juices, but it is 25% PG - 75% VG. I added it to the juice I was using and the lower vape and plugging started quickly. It there anything I can do to thin the VG products we already have in quantity?
