any one ever had an oil consumption test on a Gxp?

I am roughly 1500 miles into my oil change, this was my first oil change since i bought the car, but i checked it today, (habit in fear of blowing the engine with every car i have owned), and it was a quart low. They say that an engine that burns a little oil is a healthy engine but not that much. Anyone know of any possible solutions to this? The midpoint of the next oil change i will, if still burning a quart every 1500 miles, going to add lucas oil treatment.
 


A known issue with early DoD/AFM motors.

When it goes into 4 cylinder mode, oil is allowed to make it's way past the piston rings that arent firing and thus it gets burned off when they turn back on. It can also seep past the valve stem seals or even from a poor PCV system.

GM says that 1 quart per 1,000 is normal. Though in reality it's not that great to have to keep adding oil all the time. It's worth a shot to change oil brands/run a different weight or try oil treatment. If it was my car and I had this issue, I'd run some rotella 5W40 T6 full syn oil, popular among some of the trucks that see this problem aswell.
 
1qt per 1,000 miles? Well shît , why even have a drain plug. Just wait 5,000 miles, add 5 fresh quarts , filter and be done with it. Simplest oil change ever.


But really though - that seems awfully high
 
Hone the cylinders, new piston rings, all new DoD/AFM hardware would fix the problem for a while. Or just turn it off or remove the DoD/AFM.

My 2012 truck has DoD/AFM and uses no oil really, other than the normal half a quart or so from the PCV misting oil into the intake manifold. They did fix the issues later on.
