ONLY if clear juice - most VG I'll run through my attys is 50vg/50pg - dark juices (vanilla, chocolate, coffee) only 100% PG.
I find 100% PG less sweet and I can vape it all day on a standard ego-c atty and not get one bad hit and hardly ever lose, burnout or need to clean an atty, coz it's so runny and less viscous. I do try to stick to one juice per atty also.
I vape at 6mg.
