API SP+ May Be Coming
Here we are in the middle of May 2020, waiting the First licensing of API SP engine oil to hit the shelves & they're already talking about a SP + addendum for a "aged oil LSPI test". Seems there may be problems with some SN + & SP recipes, after being in the engine for a while & currently the LSPI tests are being run only with New / Fresh oil in the crankcase!!!!
All this as manufacturers are specifying longer OCI's. More about the subject & the possible SP + category here. https://secure.viewer.zmags.com/publ...6#/104c00a6/32
If you have a Turbo DI engine, probably not a good idea to opt for longer OCI's on SN +, or SP engine lube for a while, until they develop a good telling LSPI test for aged engine oil.

Already have enough UOA's of my own to support how terrible extended OCI's are in DI engines. I can't get 4500 miles without the TBN going below 2 or the oil shearing out of grade. I finally just got a sample of the new dexos 0w20D from the 3.0 duramax and am curious what it looks like.

Ya know I've been so far behind the curve on these extended OCI's as I've continued changing about every 3K miles regardless what formulation I'm running. So if we're going backwards on these intervals am I still behind the curve or accidentally out in front?

I did 3000 FOREVER
and changed to 5000 a few years ago
but no D.I. except one car we had and its oil looked like diesel oil in short order
I have always thought that one day ordinary poeple will be prohibited from buying, transporting, changing oil etc. It will be a controlled substance and only licensed poeple will be allowed to deal with it.

BUMP:
Well it took longer than I thought it would but 4 auto mfgrs here ILSAC requests API to develop a supplement to API SP - F&L Asia (fuelsandlubes.com), have finally hurt enough to have drawn up, signed onto & sent a letter to the API, saying they need a Aged Oil LSPI Test, as API SN+ & SP, LSPI tests are performed on New / Fresh oil as noted above in post 1. SO as speculated 15 months ago, there were indications before then, that a Aged Oil LSPI supplement test was likely needed, but it seemed no one was hurting enough back then, to put the need in writing & hold up the release of API SP any longer.
Note at this point there still isn't any Definition for "Aged Oil", or whos "Aged Oil", SN+ or SP recipe, LSPI protection, isn't holding up!!!! It's also known that fuel composition, quality, engine design, drive cycle type & other things, are players in this problem. SO, a "one size fits all" fix probably isn't likely right off the bat, thus expect it to take a while to sort out, so the players don't feel like their ox is being gored & sign up for a fix.
See what a sticky wicket this is likely to become, example; for the offending lube marketers!!! If word got out that their LSPI recipe doesn't hold up for the auto mfgr's OCI, folks would drop buying their products like a hot potato!!!!
To perhaps know, watch which brands SN+ or SP recipe gets changed, watch for new marketing terms like, new, new & improved, better than---etc.!!!!
What do we do in the meantime, until this gets better understood & sorted out??? I'd not opt for extended OCI, or with engine oil recipes still high in Calcium, or Sodium..
Consider opting for a full synthetic engine oil, or at least a blend, that oxidizes slower, would likely be a good idea, especially if the engine is a hard working smaller displacement direct injected, or a turbo di, that's lugged often during the drive cycle, like in stop & go traffic, or in hilly terrain.
Example, the Daughters 2014 Kia Optima normally asperated 2.4L 6speed auto is programmed in ECO mode such that around town, or on grades, it Lugs the heck out of the engine, before down shifting. So when I drive it in traffic, or in hilly terrain, I turn the ECO mode Off, or Manually downshift to get the rpm up some, so it doesn't Lug the engine.
Its just a Programming issue but mfgrs are pressured by the Govt to lower emissions & demonstrate increased mpg, so our engines get lugged more than they rightfully should & thats LSPI territory, so down shift that puppy early, or just turn the ECO mode Off, is what I do & suggested she do also.
Lastly I'd probably opt for a Top Tier fuel from a station that moves a lot of it, so we're using fresh gasoline that has a good fuel additive package.
More thoughts for consideration.
