Specs of Dexos1G2 vs SN+

But as previously mentioned, whether you agree with GM or not on the business aspect of Dexos royalties, you have to agree they have pushed the oil industry to do better. It's impossible to find a conventional base Dexos oil and there are very few syn blends. It also pushes consumers who are only price driven and before would have blindly put a $19.95 Jiffy Lube oil change into their TGDI motors and run it for 10k miles to start using better fluids.

A oil company that paid money for the actual testing to be done.

And remember... Any oil blender can put anything on a label...

I like the Dexos Gen 2 synthetic oil made by Cam2 I have in my VQ right now...

But on the PDS about it they say it meets Porsche C30... I don't necessarily believe that... Porsche C30 oils typically have a HTHS of 3.5 or just a bit higher than that and that oil is a low saps oil has well. Which the Dexos approved oils are mid level saps oils.... And the highest HTHS of any Dexos approved oil is 3.2...

All things being equal a D1G2 oil should provide better wear protection for your timing chain and a lower noack (it's been said), so in some sense it's a "better" lube than an equivalent non Dexos lube. Now that changes with GF6 because I believe GF6 incorporates the same requirements as D1G2 with respect to timing chain wear. Kudo's to GM for pushing oil formulators to make better products...we all benefit from this whether or not we buy a Dexos "approved" oil.

Very, very good post man...

I do agree that it is a bit annoying that there is a "extra" charge for a oil that is Dexos approved... But it ain't too much given Havoline Pro DS is at $3.33 a qt regular price at Wally world...
