@Burla (or anybody else who may know), per our convo about my UOA, I'll be switching to Red Line 5w30 (from PUP 5w30), is it still recommended to add 15oz Lubegard? Amazon has the RL for $55/gallon, and seems to be the best price I can find.
x2 not needed, and we do not know the effects of mixing two different esters.

I think the new formula was rolled out in 2021 for redline euro 5w-30. I overlooked it completely till this past summer. Im not sure how it compares but its high ester i believe the same amount as the old school redline 5w-30 along with the rest being dodecene pao

I guess I don't see any benefit for any of us. Red Line 5W-30 is enough for Hemi's, and overkill for GDI Turbo (i.e. - too expensive for frequent oil changes).

Hence, Red Line or HPL for Hemi's, Mobil 1 ESP 0W-30 for GDI Turbo's.

Yes?

You might want a hearty oil to protect an engine from bmep but then you need a low additives oil to prevent lspi. Why di's are so challenging. A perfect oil for a di, hearty for protection and low additives for bmep pressure. One thing I will never give a isht about I call tell you this, no di turbo for this boy.

Didn't we say that using Mg in place of Ca for detergent mitigated LSPI?

I'm not talking about lspi, I am taking about bmep, as in you don't see how the idea of a hearty visc oil would be beneficial to di. Your cylinder pressures might disagree with you. High lspi quencher additives such as moly and zinc plus a low shearing heavy ester oils might just be the answer for bmep and lspi.

Yes I fully comprehend high bmep with need for higher viscosity. Elementary tribology.

Mobil 1 ESP 0W-30 for 5k oil changes $29. Red Line two different oils for much more. Only needed for Hemi due to high moly and maybe esters - not needed for GDI turbo. GDI turbo only needs higher vis, LSPI additives, and heavy detergent.

PUP 5W-30 ain't making it in the high viscosity area under API SP certification. Hence, Mobil 1 ESP 0W-30 provides both LSPI additives that meets SP AND higher viscosity that violates SP. Perfect. For < 5k OCI

Just build the best oil in your head then proceed with what's reasonable. 0w30's with the euro spec are like close to the best oils you can buy, but as far as the actual best oils you can buy there is a reason for HP oils. I'd much rather have a 0w30 on a short interval considering everything, but then again that is just a theory, we will likely never know whether if you run HP oils or euro 0w30 or house 5w20 so on which would actually give the best lifespan. I agree 0w30 euro seams the best option, especially those with decent moly. Now for guys who tach there bmw's and think they are actually the next Jeff Gordon, maybe HP oils will be the best choice.

P.S. - I have some PUP 5W-30 API SP yet to burn off (pun intended), which will hopefully be sooner rather than later as wife has been recalled from WFH to downtown office 3 days a week, and son works full time.

I already have a supply of Mobil 1 ESP 0W-30 courtesy of Travis' info. I plan to pull a VOA/UOA for the forum's benefits, since engine action today is all about GDI and turbos.

Btw, GM announced yet another new V8 development, much scuttlebutt about it. Whether they're resurrecting the flat plane architecture or what, enthusiasts are telling them not to include 4 cylinder cutout. ha ha ha

Brian, see the problem I see? CA/mag?

It's a great oil, great examples on BITOG, I just wouldnt run that CA/mag level in a di turbo if it were me.

How can that legacy Ca/Mg antiwear additive "meet or exceed" API SP LSPI test? Yet Mobil claims it does in big, bold public print.

It has a bunch of Boron additive, though. I think @Travis8352 mentioned something about Boron additive being the new witch's brew recipe for antiwear without LSPI? The UOA poster didn't mention any engine knocking.

Viscosity didn't shear much under high BMEP, either @ 4,863 OCI, @ 11.6 cSt / 100C (spec sheet typical new is 12.0 cSt / 100C)

Mazda is very clear they want 5W-30 in the turbo motor (the NA motor calls for 5W-20) obviously for the higher BMEP. So I want a real SAE 30 wt, not watered-down API SP PUP 5W-30.

Imma try it. If I blow it up, I blow it up. Wouldn't be the 1st motor I've blown up. Hell, my youngest has blown up two snowmobile engines and a motorcycle engine to date already. He's only 25.

At least we don't have exhaust diapers. Ford announced they're starting to put them on. jfc

P.S. - thanks for digging out the UOA from Bob's, Mike - I don't go there much being banned for life.
P.P.S. - why is that guy's fuel dilution so low compared to mine? Mostly highway (steady-state engine load) miles, where ours is a mix of city and highway? My UOA was ~ 2.5

The fuel dilution will be what it is regardless of oil, and I was wondering as well how that oil is sp with 1500ca/70mag, doesn't make much sense when most sp seams to be like 800 ca/5-600 mag. To be honest if it was my DI I wouldn't care much, I know CA is bad for it, so there are many oils to chose with a better add pack for what we know. Those euro oils are great for a hemi! Great visc, every example I have seen and there are a ton, that oil is great at not shearing for a 0w30. But lspi is a different conversation, as to be honest I am a little disappointed at m1, cant figure why not build that oil with less CA and More Mag, whatever on that deal/

:33:

These are my VOA for PUP earlier this year, and the one you posted from BITOG of UOA for M1 ESP 0W-30, Mike.

IDK why this picture came in dark from a white Excel spreadsheet. I just typed the lab numbers in for direct comparison. Spec Sheet Vis for M1 is 12.0 cSt @ 100C.

Mobil's formula is to through more phosphorous and zinc in and leave calcium high and magnesium low. I have no idea how that "meets or exceeds API SP for LSPI".

:), yeah I wont want. Even if I could afford which I can't. Early ram 4 gens or early-mid 90's f150's for me, if I ever need another vehicle which I kinda doubt since I inherited my own rav 4 from myself, lol. So I even have a back up. Maybe a RAM 2500 any age even new would be ok too.
