Don’t get me wrong, we appreciate your contribution. My comments are strictly focused on how the lube performed in this use/case scenario. I don’t think anyone can convince me that this oil can perform better than $15/5qt Kirkland or even a regular syn blend like chevron supreme

Don't really know this. Given all the idle time and fuel in the oil.
