BTW - I have no business relationship with RLI other than being their customer.
With free shipping, this really is stupid cheap, less expensive than QSUP from Walmart.
Make sure to use link above or find it via RLI's homepage banner (which says sale goes through end June), because regular item #85121 shows a $13.77 price. Sale item codes are #85121S (quart) and #85121SC (case of 12 quarts).

Sample submission process is described here, and for me it has been extremely efficient for the three samples I have submitted to date.
I emailed Lake the historical trending data from the other lab to help inform current analyses.
I am not sure if their lab is ISO-certified, as @danielTRLK had recommended several years ago. I asked but did not get a complete answer.
Curiously high Iron count this interval, not sure why.
RLI PCMO has very little MoS2.
Wear / 1000 miles metric corrected for previous sample.
