Most resilient oil to GDI intake desposits please

Browsing the first 6 pages of the UOA section and found the following calcium contents, from lowest to highest:

1100 ppm - M1 5w30
1100 ppm - M1 EP 5w30
1100 ppm - M1 HM 5w30
1300 ppm - GM dealer bulk 5w30
1700 ppm - ACDelco 5w30
1700 ppm - Castrol Euro 0w40
1750 ppm - PP Euro L 5w30
2000 ppm - PP HM 5w30
2100 ppm - Castrol Edge EP 5w30
2100 ppm - VSP 5w30
2100 ppm - Kendall GT-1 5w30
2300 ppm - PP 5w30
2300 ppm - PP Euro 0w40
2400 ppm - PUP 5w30
2400 ppm - Castrol Edge 0w40
2500 ppm - Castrol Edge 0w30
3000 ppm - M1 0w40
3300 ppm - Amsoil SSO 5w30
 
Looks like M1's signature 0w40 is out of the running, as is Amsoil, if we are to follow the TSB language.

Now the question is, what is "low calcium"? Below 2000 ppm? Below 1500 ppm?
 
Old UOA can surely be used as reference. The few VOA of d1G2 oils we've seen show a significant Ca reduction to what they had when only certified as dexos1, so don't choose according to that list you just posted. Choose something that's certified. That alone should give you confidence you've selected wisely.
 
Some of them will no longer be relevant. We already saw QSUD changed their formulation for D1G2.

Amsoil just reformulated their Signature Series oil for the LSPI protection and started shipping it in September of this yearso you will have to look for UOA's I would say from December 17 onward for the new levels. I know I still have the old stuff in my stash but luckily LSPI isn't a problem in the Journey.

Quality fuel, long drives and more often than not WOT's all help.

Ecoboost engines seem to like Castrol Magnatec. I would go with that oil personally. Plus it's cheap.
 
My memory is that BITOGer Molakule formulated an LSPI-resistant oil with ~1600ppm of Ca...assuming that the AC Delco 5W30 referenced above is their synthetic, I guess I'd take its 1700ppm as an upper bound for "low calcium".
M1 5W30 ESP was another oil in the 1000-1200 ppm range for calcium.

BTW, here's a webpage with a couple of plots showing the effects of calcium and ZDDP concentration on LSPI from one particular study.

Granted, i don't know if GM's 2.0T has a LSPI history.

Thanks for the link. Interesting info!

Yeah, I realize that there will be little to no D1G2 UOAs yet. It will be interesting to see how the new D1G2 formulations will compare to their old formulations.

If I was a betting man I would put money on D1G2 requiring less than 1500 ppm.

It would be nice for GM/Dexos to define "low calcium" in terms of ppm for us oil nerds.

Thank you!

Really looking forward to these.

I spoke with the dealer today and they confirmed they only use full syn 5w30 Dexos1 Gen2. All their oil offerings are Gen2 now.
 
For temps down to 0 degrees F. M1 10W30 with NOACK down around 6%.

At 50k the car pinged so badly, I had to run a GDI cleaner through the engine while it was running.

It cleared up most of the pinging issue but about 10k miles later it still pings when the car is cold under load on 87 octane.

I also run techron at every oil change.
 
Older Hyundai / Kia GDI engines are worse for deposit build up than newer (after 2015) GDI engines as Hyundai / Kia have improved VVT and other tricks to reduce deposit build up .

Anyone have a UOA or VOA of M1 5w30 ESP handy?

The Russian Oil Club has a fairly exhaustive one with NOACK and CCS performance, I honestly only visit that site when I "have to" these days but there is a thread linking to them in the VOA forum on BITOG.

After almost 90K miles (GDi deposits usually appear much sooner) and running mostly (not exclusively) 93 octane with the following oils, i can report not one single drivability issue. I previously owned a 1.6L Veloster that was sold with over 80K miles. No issues either. Maybe the south Florida heat works in our favor.

Oil...........Times used
VSP 5W30......10
M1 5W30.......03
M1 0W30.......02
VWB 10W30.....02
Edge 0W40.....01
Delo 5W40.....01
Devlac 15W40..01
(Might have left out a change or two)

Not one issue except for fouled spark plugs when changed at 40K.


I think the warm temps and the high octane gas are a perfect combo for these engines!

Slightly off topic, but I just checked the list of dexos2 oils on there and they have one wrong. They list Castrol Edge 0w40 as being dexos2 but it's definitely not. The only 0w40 that has the dexos2 rating is M1 0w40 ESP.

I'm looking for possible dexos2 alternatives for my Corvette in case M1 0w40 ESP is priced way too high or is very hard to find. I'm considering M1 5w30 ESP or Pennzoil Platinum Euro L 5w30 (both low saps oils with a 3.5 or higher HTHS) My Corvette also uses direct injection by the way.
