As an aside, I wonder what will happen to the engines as these cars are passed down the food chain as cheap used runners to their second and third owners? Will these engines get appropriate oils, or will they be run on unsuitable ones having only the virtue of being cheap which will hasten the demise of them?
I'd suspect the latter and we may be seeing the first generations of mass-market engines where oil selection really does matter and no shortening of drain intervals will help with this.
I would think that most oils will eventually conform to the new d1G2 standards. They should work just fine on most older vehicles.
Most name brand synthetics will meet these GM standards.
Most oils across the board may not, or at least not within the next ten years.
The average new or used car buyer won't be charmed by the notion of very expensive oil changes and many will go for something cheaper at their peril.
The old mantra that frequent drains make up for any deficiencies in the oil won't work in this case and these turbo DI engines are used in some fairly cheap cars that are bound to show up at the local buy here pay here in fairly short order.
