I figured the sharper than me guys (most folks here) would be all over this.
Did you note a comment he flashed on the screen during the video was from a *gulp*....Project Farm video?
Will LSJ videos be banned as PF ones were?
The old oil had oxidation values around 65 and 100, respectively. Are those values within a range explained by expected formulation differences?
Not slinging mud.I don't get the fuss over the oxidation value. It tends to show a general trend and that oil doesn't have ester. It seems like a desperate attempt to sling mud to me. I see comments so not disabled.
Great video. There's more to come.
We cannot know unless someone ran a virgin sample back when (this could be possible)
So if I understand you correctly, you’re essentially saying it is possible the old oils had enough extra ester to have higher oxidation by 50-90. Is it parsimonious to conclude that?
We simply don't know. There could be another additive or base oil, not just ester.
You go to the store and buy the oil on the shelf rather than stocking 20 yr old bottles of oil because they were "on sale".
Water causes oxidation. Take the M1 in the can as an example. We know it has no ester because M1 wasn't using it at the time.
It is not my purview to moderate technical points.
Not an answer, move along.
Water can contribute to oxidation, as can air. You are 100% sure no esters in Mobil1 at that time? I am not so sure. Plus we don't know what else may have contrubuted.
He’s also addressing a broad audience that may not be so technical. He simply may not want to confuse anyone by qualifying that statement. It’s likely those oxidation values are elevated over the original numbers.
Wins BITOG big word of the day contest. Had to look it up.
When two assumptions have unequal likelihoods, the more likely assumption is usually better.
You have a point but listen to his exact words.
Feeling attacked?
Nah, deflecting an amateur junk answer when i'm trying to get a tribologist to answer the next steps, reviving 40 year old oil. I dont accept the "bad oil" answer from Lake Speed.
Per LS that particular 1970's era of M1 was PAO with Gr1 as the carrier. In any case I don't know what type of esters were used 20 yrs ago but as you know some esters oxidize in the presence of water. I get what you're saying but how is it relevant? The anti-foaming agent is shot and no mixing will fix it, TAN is high, water is present, oxidation is high. Circa 2000 weren't Castrol and M1 the only PAO/Ester brands?
