I am not sure they off the ook.. I pour it from their bottle sealed... I between them and the vendor the fault lies. Proving which will be an up hill battle.

Mg: 687 0.71
Zn: 640 0.66
Mo: 73 0.08
Bo: 43 0.04
We should be looking for similar ratios of these elements in the mystery goo UOA to see if it has the fingerprint of M1 0W-20 EP but at a much reduced concentration. The answer that it does NOT have a similar fingerprint. Mystery goo numbers are the following, with the second column values using Zn as what they are relative to since that has the highest concentration. The third column numbers are relative to Calcium since that is what was used in the above set of relative values.
Ca: 86 0.46 1.00
Mg: 59 0.31 0.69
Zn: 188 1.00 2.19
Mo: 9 0.05 0.10
Bo: 11 0.06 0.13
Both columns of ratios indicate the goo does not match the fingerprint of proper M1 0W-20 EP. The third column’s values are a pretty decent match except for Zinc. Boron is a bit off but it’s a squirrelly element in UOAs since it tends to reduce in concentration over time. I could have included Phosphorus too. It’s trend is similar to Zinc’s trend, which is present in a much higher proportion to the other elements in the mystery goo than it is in the proper Mobil 1. If this was due to foul play by some person, it could be due to someone mixing something lacking in additives along with some M1 along with a ZDDP additive. Very strange situation and I hope Mobil is gracious enough to reimburse you appropriately, even though they may not have been the cause of this mess. It’s one of those things where it may be better for them to plead no contest without accepting guilt.
TY for your your analysis.. Interesting way to use the fingerprint % comparison.
I worked with concrete batch plants before.. In a course of 3-4 years. things fail in the plant several times that cause bad product that you can not tell unless you test for them daily (on big pours we poured 3000+ cubic yards a day, we tested 20+ times) Sensors, valves, scales.. would fail. Things happen. Sure we would stop and reject concrete when they fail but there will be a few loads that gets placed before we notice anything.. long story short, sometimes mass produced items may have quality issues that gets out even with the best QC.
Can someone tampered the oil before/during my ususage.. of course there is always a chance but I would say highly unlikely. more likely for a bad batch of oil..
(yes i note nothing has made the news yet about a mass oil failure)
IF I go off the air and the youtube channel you can speculate that I got taken care of!
