I talked to my dealership and they said in all the G37's (our VQ37HR engine) the only time they've used the Ester oil is for the TSBs - never had a single client do an Ester oil change in the last two years.

Keep the reciepts if you must for warranty, and DIY.
They can't hold you responsible for DIY oil changes short of it being obvious, such as not putting in a drain plug or too much oil.
Also, Ester is not a requirement.
