I was carefully monitoring my oil consumption on my previous 06 G35.
It was sometimes difficult to get a good reading but Infiniti did improve the dipstick on the G37
My 06 G35 dipstick in a vise with a mm ruler measuring oil consumption.
I always checked my oil weekly
I never qualified for a new engine but sometimes used a qt/1000 miles
Other times 1 qt per 2000 miles
I just added oil when it needed a 1/2 qt and traded it in at 171796 miles
