Well I'm at my Nissan Dealer getting my 1st oil change @ 1500mi. Sure enough the service rep had no idea about the Nissan Ester. They wanted to put regular oil in the car until I pointed out that the 370z required the Nissan Ester which of course they had no clue of. (Thanks to semtex for the pic which I printed out and put in my back pocket just in case.) I asked them if they sold the Nissan oil and sure enough, a knowledgeable parts rep brings out 5 quarts from the back room. They quoted me about $95 for the complete oil/filter change. Fortunately, my first service is free.
The 370 is now in the back getting the correct oil changed out. Thanks to this forum and all the great input you guys provide.
PS. I also expressed my concern regarding the high oil temp while in traffic (240F). I don't expect them to find anything, but at least they'll have a record of my concern.
Nissan Ester Oil (1qt) 5w30 - $12.99
Motul 300V (2L or 2.1qts) 5w30 - $31.95 (was recommended replacement per the parts rep after the first few oil changes)
