I can't say I've noticed it but I was using max VG before, and now I'm adding in water since I can't use PG, but it IS keeping temps in my vape down. I was surprised that I liked it, but I really do. It's an easier, airier vape, but the flavor is better. I will be keeping an eye out though, and also making sure my lids stay on pretty tightly (the e-juice I've done that to is pre-steeped, so no worries there). I also don't usually make batches more than 55 ml at the moment, though I'm sure once I discover some favorites I will be making more-- maybe. Because I only go through about 5 ml per day.
