He says they seal her up for about 1k miles (unless the customer KNOWS she'd fail dry before then) and then check it after the 1k miles. Then you get free pistons and rings.
In my opinion, you should have the oil consumption test done now.
Here's why:
Fist off, once the test is complete, you will know for sure, that you will or won't qualify for the work to be done, right now. If the car doesn't burn enough, you will get another chance to do the test again (or several times) before you run out the 150k clock.
Second, if the car does burn enough oil to qualify for the piston and ring replacement, and the work goes without any additional issues, and it cures the oil consumption issue, you then don't have to worry about all this extra oil you have to keep replacing in the engine. You save money from now, AND the projected lifespan of your engine actually increases.
Third, if you get the work done now, and yet it still burns oil, you are still guaranteed to the 150k mile mark. You can get it done a second time, and I would recommend trying a different dealer, who probably has a more successful engine rebuilder on staff.
If it was one of my cars burning oil at that rate, I would schedule the consumption test setup on Friday morning, then I would hop in my car, and drive 500 miles east to Ogden, KS, spend the night, then drive back home. The next day, car would be back in the shop to confirm the oil level, and proceed with the repair.
Somehow I've never managed to wind up with a car that burns oil during the warranty period. Life is just so unfair.
