LSJr ... Talking Engine Oils of the Future

[buster]

Discussion on innovation starts at 15:48. Talk about metallurgy changes, hypothetical no need for deposit control and use of less ZDP with engines that use DLC. Re-thinking chemistry from ground up.

Watched this earlier in the week and was interesting to hear about the other types of contamination being accounted for.

The good news is that this forum will then stay abuzz with plenty of old and new questions.

I'm convinced there is only one way out of oil obsession - EVs. LOL

Don't they still use lubricants? I know they don't get the same level of maintenance due to lack of contaminants.

We can start obsessing over the various gear or bearing oils used in EVs. Oh, we need a new "bob is the coolant guy" forum to discuss battery temperature conditioning.

 

[buster]

LOL i could see that.

 

[Boomer]

Nah, we will be talking about battery additives that "double the range of your EV" or that" prevent battery degradation for 5,000,000 miles". And, believe it or not, it will probably contain Teflon particles! There might even be a Marvel Mystery Battery Additive to discuss.

Thick vs thin battery design.

Thick vs thin battery design.

In a future generations, they'll argue about 240 V vs 1.5 kV charging. My grandpappy never went above 480 V and his batteries never failed. Yeah, but new batteries are designed for 1.5 kV charging. They have tighter clearances. Yes, but the manual for Mexico says they can be charged at 240 V. That 1.5 kV charging is just to meet CAFE2 regulations.

I will still drive around with a jug of M1 0W-40 in the frunk.

I see a BITBG. Battery guy.

As you reference, at ~ 18:00 LSJ says too much ZDP is not a good thing for DLC (diamond-like coating) engines.

I check in at ~ 875ppm with my HPL PP 0W8 and 2024 Corolla Cross Hybrid w/DLC.

I ask our experts, how much is too much ?

@High Performance Lubricants
etc

TIA !!

 

[spasm3]

I am wondering if we are approaching the point that oils are as good as they will ever be ?

 

[Indyxc]

We talked about this in another thread, but both oils designed for DLC coatings by Mobil (C40 GT) and (Supercar) have relatively high ZDDP and medium Moly. SO who knows.

Here we go again with LSJr.

DLC is used as a way to allow the use of less than robust lubricants. As expected, the DLC has a limited lifespan.

Thank you Sir.

From what I am reading as a layman, physics and chemistry come into play.

DLC depletion rate is influenced by viscosity, temperature, pressure, naturally.

But other factors include respective engine parts, metals involved and interactions between the various components, forms and dosages of the ingredients in additive packages and base stocks.

Most oils seem to fall in the ~ 725 range in ppm of ZDP. Valvoline VR 1 can be ~1100-1400. Somewhere in between is where DLC depletion rate has to be considered noteworthy.

Not all forms of ZDDP and moly attack DLC the same and not all DLC are created equal as well, so it's complicated and probably requires case-by-base validation and why the C40 GT specification was necessitated in the first place.

Wasn't that the whitesnake song ?

Some of those M1 oils have Zinc levels which are creeping up towards 1000 ppm.
