Why would you even put yourself in the position to have to ask? DIY and you know what when in there. I just had to replace the Air filter box on my Toyota was a bit of a hassle but I did it for just under $30 ordered the part on Amazon. The Stealership wanted (hold on) $664.
Head in the back and ask the techs. They'll give you a straight story I'd expect.If in fact they do use Mobil Synthetic, would it be Mobil 1 or one of Mobil's lesser synthetic's ?
Talked with Nissan dealer, the oil that is bottled Nissan is Mobil, not sure of what specific level of full synthetic it is.
The bulk oil they have is a Private Label full synthetic that meets Nissan requirements.
They charge $70 for the oil change, that is for 5 qts.
