if you can afford double the price for redline and have no issues replacing it RELIGIOUSLY at 3k miles then YES it is prob the best oil to use. for me its overkill and expensive.
(i even tried M1 0w-40.... the oil heated up quick but i noticed my engine burning more off than normal. so i went back to 5w-30.)

Do you have any scientific backing to this besides it looked dirty? UOA? An oil can be dark and still be perfectly fine.
Nissan recommends 3,750 anyways. The reason they also recommend ester is for the VVEL. The biggest thing to running a higher quality oil even if you change it the same amount is to stop and prevent wear. The ester oil also has many more inherited beneficial properties with it.
