What do you use to treat the leather? And why so often? I'm not nitpicking, genuinely curious...I just bought my Yukon a few months ago and this is my first experience with leather seats this old.
I know that with leather conditioners, the oils soak in, with that said, your clothes wick the oil away a little bit at a time. So I started using Griots Leather conditioner, works great, not greasy like many others, soaks in real well... I can tell a difference in my leather feel after a few times of using it when I first got it, softer, little more pliable also... Compared it to my moms 14 Yukon denali and now Mom and dad both use the same conditioner on all their leather goods. See a over 40 man can still teach his parents something sometimes. Most seats crack its one of those things with leather, keeping the cracks small, and minimal makes them not go huge and actually split. It pro longs the life of the leather for sure.
