I came across this comparison spider graph on the Lubrizol website. Unless my eyes are deceiving me, it looks like D1G3 has a lower standard for wear and sludge protection compared to D1G2. Are motor oils getting to the point that piston cleanliness, LSPI, and turbo charger cleanliness, are beginning to sacrifice wear and sludge protection?
Dexos 1 Gen 3 Comparison 2021

The latest generation will probably require a further reduction in calcium and phosphates (including zddp) to achieve the reductions in low speed pre-ignition and catalyst poisoning, hence the lower wear and sludge protection.

When will Dexos 1 Gen 3 be available??
I think I read that the suite of tests for meeting the specification will be officially released May 2021. No Idea when oil meeting the spec will be on shelves.
September 2021 is the first license date I read.
It's hard for me to understand these charts without any meaningful numbers.
You got an A and scored 99 vs. 96.
yes 99 is better but I would even take 91 ...
relatively speaking is the most inner circle like F, then D, C, B and A?
when it comes to oil, how do you compare a better d1g3 (one that exceeds the minimum). Are there specific charts for those?
These look like charts you give to high level management to leave you alone ... lol

Yeah man I'm with you on that... Maybe Lubrizol jacked their gragh up...
And like you said it would be a good oil.
I'm sure it's correct DP are trade offs. Plus these are MIN standards; remember when you read the back of
most of those "premium" oil bottles they say they have " 43% better wear protection than required" ?
Managing deposits on ring lands, preventing hot and cold stuck rings and managing deposits with turbo bushings and cam phasers and their actuator plungers and valves AND TCT plungers are likely the MOST important requirement on new engines.
The Manufacturers have this engine failure data, hold it close, then work with industry to improve the lubricant.
Excellent point.
As one can see by the graphic, D1G3 is or will be a more "well-rounded" oil.
That’s true!As one can see by the graphic, D1G3 is or will be a more "well-rounded" oil.
My only question is at what cost and what real gain?As one can see by the graphic, D1G3 is or will be a more "well-rounded" oil.
Based on the first and second post in the attached thread, GM has set more stringent standards for D1G3 motor oils. I don't see how that is a bad thing.

Will refiners/blenders have to pay GM for a new license?
Yes well that all nice warm and fuzzy but what is the real gain and the final cost. I see very little gain here except for GM's licensing costs.
Undoubtedly, GM will extract monies from producers for their licensure. Nevertheless, many if not most engine oil qualities are becoming stricter. It is what it is.

Remember, friends! Dexos is a GM specific....erm, yeah, well.... specification.
More than likely the oil spec will be in relatively sharp focus with GM vehicles, predominantly.
It may be very well LASER sharp on a recently recalibrated vehicle or soon-to-be-released Generic Motormunchers creations.
Yeah? ;>
