D1 / Gen 3 Approved Oils Wear Ranking ?

[Patman]

Are you saying D1 / Gen 3 oils are not approved for Cadillac , Corvette or Camero ?

Actually, the newest Corvettes call for a DexosR oil (factory fill is M1 Supercar 0w40) so dexos1 is no longer the right choice. It’s very likely that Cadillac and Camaro are the same (at least in the ones that use the LT engines)

Isn't GM making a change to their Dexos ratings? R being for gas and D being for diesel?

The cheapest full Synthetic (SuperTech High Mileage Full Synthetiic) is Dexos 1 Gen 3 approved.

The Dexos 1 Gen 3 approval details I care about the most are it's limits on sludge and deposit (varnish) accumulation.
SuperTech could be a better oil to prevent sludge and varnish than any API SP oil that doesn't have the Dexos certification.

apparently it's living rent free in your head as you replied to it. I simply made an opinion which this forum allows and you tried to come in the snub me for it.

Simply? You made an arrogant statement that judges everyone here who is more curious than you are …

IMHO, Dexos is just a marketing scam for a sub par car company to try and turn a profit somehow someway.

Here is your statement again - simply put …
(You should have removed the H) …

Depends on those models/engines - highest HP V8’s in that case would now be this:

Dexos1 was never the right choice I think; they specified Dexos2.

At the bottom after boutique oils and Frankenbrews done by BITOG members

Are you calling my 50/50 blend of 20w50 motorcycle oil and 0w40 T6 in my lawnmower a Frankenbrew?
Abby Someone told me that it’s okay.

For many years (dating back to 1992 I believe) the Corvette called for a dexos1 5w30. My 2018 is the last year of that actually. Beginning in 2019 the factory fill was ESP Formula 0w40 which was a dexos2 oil.

Ah, yeah, mostly pre-C7.

Maybe. First, you should know the OP has no car that requires D1 G3 as far as I can tell. Look at his thread history also. This is some weird spec fetishism. Second, I’m going to stand by the assertion that D1 G3 is not anything special. The Lubrizol tool, used correctly within a single manufacturer, shows it is inferior in most ways other than LSPI test to Dexos2. Since there are now Dexos2 (ACEA C3 based) oils with SN+ or SP additive packages, I see zero reason to go hunt for D1 G3 oils if your manual doesn’t call for it. If D1 G3 was so good, why does Cadillac eschew it for performance turbo DI engines? Every good gasoline engine from GM specs Dexos2/R. D1 G3 is an economy car engine oil spec and I’m sure cost sensitivity is a driver of this differentiation.

which Cadillac performance turbo DI engine calls for other than Dexos 1 Gen 3???...the V8 based engines call for Supercar but I haven't seen a change for the twin turbo 3.6 V6 or the smaller turbo DI engines...

Seems I was incorrect, the V8 BW uses it but not the V6. Not yet, anyway.

 

[silversport]

...and haven't for 12 plus years now...do you have a specific reason why you think they would change to Supercar oil over D1G3???...I've not read of oil related issues when using Dexos oils in the LF3/LF4 twin turbo engines (or the single turbo engines) either with those running them on a track or just streets...
