What oil are peeps using for their oil changes?

The K&N problems were due to people tightening up the filter with the nut are they not? K&N specifically tell you not to use it, it is to aid removal only where it doesn't matter if you do any damage. Far too many people on YouTube tightening the crap out of oil filters when hand tight is just fine.

No, Tev, I don’t believe that’s right. There was a batch of K&N filters that had a flaw and leaked. The rest are probably fine, but, having experienced the failure at second hand, I won’t be using K&N filters.
