A DoE paper concluded that octane was not a factor in LSPI.
Edge 0w-40 is low calcium at 1600ish, and has the nano titanium dioxide additive, which is one chemical that "quenches" LSPI, so that's what oil we're going with for the wife's new Golf SW 6M.
Another chemical additive the quenches LSPI is moly. I have a bunch of Pennzoil 0w-40 SRT here, with moly at 250, so even though it's high calcium I'm going to use it up in my new MB Metris van 2.0T 7A.
One overlooked oil is Pennzoil 5w-30 Euro L, a reduced SAPS oil for specs like MB 229.51 and BMW LL-04, which takes it very close to VW 504 level performance, which is the top spec in reduced SAPS. MB 229.5 is the top full-SAPS spec, far ahead of the obsolete VW 502. The manual in our 2019 1.8T finally recommends 504, which is an excellent way to get low calcium, just expensive compared to the PZ Euro L at $22/5q, which is what I have in my 2012 Avant now.
The only thing Edge 0w-40 has going against it is the fact it's full-SAPS, which is not good for intake valve deposits, a reduced SAPS oil like 504 (M1 ESP) or MB 229.51 (PZ Euro L) is "tested" by Lubrizol to reduce the build-up.
So, it's a tough choice for me, 3 DI cars, 2 brand new and a bunch of high calcium oil already stashed. Since my wife has the manual trans, she'll get the Edge 0w-40, we'll have to buy it for 6 months intervals. I should also get new oil for my MB van, but will suck it up and use the PZ 0w-40 SRT I already bought. I would be very temptedto use the PZ Euro L in it, since it has MB spec....but no VW, although it's it the same class as VW 504.
Remember, MB 229.5 is by far the top spec unless you WANT reduced SAPS, then 504 gets the edge....pun intended. Also, some oil companies meerly "recommend" their oil for a given spec, or says it "meets the requirements of XXX...". Not the worst thing in the world, Liqui Moly does it and so the Valvoline and sometimes Castrol.
LM is nothing but hype, especially when you can buy real spec oil for less, like Edge 0w-40 made in Germany & legit specs, or for even less a HDEO diesel truck oil like Rotella, or the amazing Delo 5w-40 (HIGHLY recommended for tuned cars, with it's crazy HT/HS of 4.1cP, literally nothing beats it outside of maybe Redline)
fwiw, 20 and 30 weight "API" or "ISLAC", the thinner Mobil 1 have been very low CA for a while, like 1150ppm, but the 0w-40 is the same as other overbase calcium Euro 40 weight formulas from most oil companies.
It's an interesting situation. I'll try to add some images with data soon.
