We realize that this ordeal has been frustrating for you. But at least now it sounds like your dealer is following a rather standard procedure to determine oil consumption, i.e. starting with a known amount of oil in the sump and then measuring again at fixed intervals (and hopefully under exactly the same conditions) to determine how much oil is being consumed.

I will assume that they have really ruled out any leaks since you didn't mention if they added any UV dye to the oil. But.....just to satisfy myself if it were my car, when you take the car in for the first check, I would ask the technician to put the car up on a lift and pull all of the underbody aerodynamic cladding off and do a thorough visual inspection for any oil that may be places it isn't supposed to be.
They may have been lazy and just assumed that the oil is being burned rather than leaking somewhere. It may not be a big enough leak to leave a telltale puddle under the car. But enough of a leak that it goes through 1 qt/6000 miles.

Good luck and keep us posted as you go along.

 

Thank you. They said they did do a thorough inspection for leaks (no dye).

 

Out of curiosity, how much oil did they drain out?

 

I don’t know, but they have a record of it. But I had to add 3/4 quart just to get it to the shop. I provided the oil bottle and photos as I was not gonna drive the car with it being a quart low.

 

Was 6,000 miles the first time you noticed the low level and needed to add 3/4 qt to drive it to the dealer?
As I posted earlier. my oil "consumption" stopped within a couple thousand miles.
Perhaps (hopefully) by 6K, the problem has already solved itself.
It sounds like your dealer is treating the issue fairly, and presumably you are monitoring the oil gauge..

 

Yes, as it was the first 6000 miles of ownership of a new car.
