Since my first oil change, I have used Mobil 1 5w30 extended perf.
My car just hit 45,000 miles, 17,000 of them with twin turbos at 550+ rwhp.
since as far back as I can remember, my VVEL system has been noisy as hell. Just sitting at idle, you can **always** hear it ticking away like an old sewing machine.
I am not much of a believer in the magic of one expensive oil versus another, so I never bothered with the Nissan ester oil. But if anyone can say for sure that the Nissan oil makes it quieter, I will swap over to it.
But I have no concerns of it being an issue that is going to cause a failure... because its done it since brand new, and I beat the piss out of this engine daily, and it hasnt changed or gotten any worse, etc. Its just always done it.
