Hello all, i just purchased a used 05 Maxima with 32k on the odometer. I was planning on going with a synthetic oil. Can anyone give me an idea on what the VQ35 engine thrives on? Also, should i run a dose of Autorx being that it was purchased used? I appreciate the help. Also, if there is a dino oil out there that does well in this engine, i will not be oposed to using it. Thanks in advance for the help.
