07 Cobalt using one quart of oil less than 1000 miles. Valvoline HM red bottle in now with no change in oil usage. No drips and no blue smoke. Any ideas where the oil is going.

The oil could be getting sucked through the pcv hose that goes from the cam cover to the intake tubing.

How many miles? My 06 has 90k with no oil use at all....

Tough to say-could be burning it....

It's not a pcv valve, just a hose from the cam cover.

I think GM just calls the pcv system on these an orifice, basically that's all it is.

Do you have oil collecting in the intake tubing that's on top of the throttle body?

That is the only place the oil would be disappearing to. Assuming that it is not leaking or burning oil. The intake tubing is very easy to take off. Just a few fasteners and work clamps.

If it's collecting oil then there might be a problem with the piston rings. I recall there is a member on this forum with a 2.4 ecotec Buick with a similar problem. Not sure what the outcome of that situation was.
