It's not really a testament to anything, but for what it's worth, I've been using Kirkland and Supertech in my Toyota Corolla and twin turbo Ford Explorer for the last ~10 years or so with zero issues. Toyota will hit 200k in the next few months and the explorer has just shy of 100k. I used to change the oil at 3-5k and after doing oil tests, (yes im a car nerd) I've since extended that to 7500-10k miles since the oils looked fine and had life left after 5000 and 7500 miles.

After having procrastinated for years to do my own oil changes, I decided to finally do it after seeing the 1QT cases at the biz center. I prefer single quarts over the 5QT containers. Easier to pour, don't have to store the left over from the 5QT container, and easier to store the old oil in it.

Two older (2007) N52 BMWs and a 2008 Subaru ez36 boxer engine. Each car has 160k+ miles and is consistently run hard in cold and warm environments.
