No more burning oil or valve noise. The cars revs extremely smooth. Im just not sold on all this oil debating. To me I have found something that works so im keeping with it.
Which is what many people do. Mobil 1 doesn't use an ester base, period. I have heard of and read of differences between the 5W-30 and the 0W-40. Nothing has confirmed either definitively, which will also never happen seeing as oil additives and things are trade secrets.

Generally, less valvetrain noise should be better, at least from an audible perspective. I haven't read anything about how the valvetrain noise apparently indicates premature valvetrain wear (as implicitly indicated).

If the mechanic at the shop did as he was told to, he put in what the GT-R would take for oil changes: 0W-40 Mobil 1. The weight has little bearing on how it performs (well actually that is even more complicated, but irrelevant in this case).

When looking at Mobil 1's 5W30 and 0W40, there is no real difference. Solve this problem by doing what was suggested earlier. Run Nissan's suggested oil for the Z; Nissan's Ester Oil, 5W30. End of story. Now let us close this oil thread so that it may sit among the other hundreds of oil threads that never reach any definitive answer.

Happy driving.

I guess Mobil disagrees with you. Just sayin'.

Is Mobil 1 an Ester Oil

Research told me that most all synthetics have some amount of ester additive; the thing that separates a group 5 oil like Redline from everyone else is the percentage of ester that the oil is...

Of course I just did this research now so I dunno, oil threads.

Here's a good image, despite being over a decade old.
