OEM Nissan / Infiniti Ester Oil, 5w30 synthetic.
This is the recomended oil for the Nissan 370Z and Infiniti G37, that use the 3.7L High Lift engines. Ester Synthetic oil will help protect your engine components better than standard synthetic, and can actually reduce some of the common noise the high lift heads on these engines tend to make. This will work with ANY vehicle that uses 5w30 engine oil.
Price is for 1QRT, for a full oil change, order QTY x 5.
