I'm using 1ml standard resistance cartos and PG juices with 20% or less VG and no flavoring sediment. I'm a moderate vaper using about 2-2.5ml per day. And these numbers are JUST using those 2 cartos to vape - no other cartos or dripping. And these are how long I would be able to use the carto if I only used the ONE carto.
Boge 510 (used on 510 3.4v, and 3.7v Riva and mods) - 10 days of great use. If I want I can get 14+ days though after 10 days the performance is reduced. However my cotton still goes white when the juice is low - the carto is nice and clean.
KR808D-1 (3.7v) - Vapor4Life WOW carto of Bloog carto - 7 days of great use, sometimes a few more days.
And I am telling 1/2 of how long I get because I alternate vaping one of each. I carry both models. So realtime I actually get 3 weeks on a Boge and 2 weeks on a KR8 carto splitting the use between the two.

gsiudut - yes.
PG - thin, lets through the most flavor, nicotine TH, nicotine irritation, makes thin vapor
VG - thick, dulls everything PG lets through, makes thicker vapor
Most people use blends, and you vaping method may determine how thick a blend you can use
