Oil Nerds Info

Jordo!

Yep.

Euro (AKA: German) blend Castrol 0w30 synthetic can be found at autozone.

I'm very curious to compare and contrast that to the redline after a 4K interval.

Also worth noting is that if the difference in wear is indeed due to the interval, then Nissan's recommendation of 3750 mi as an OCI for mixed highway/city driving is pretty spot on, which wouldn't be all that a shocking finding considering they built the damn thing.

Maybe, given this kind of driving, the motor is the limiting factor on OCI's, not the oil. That also doesn't seem too far fetched considering any synthetic oil should perform about as well.

Higher OCI's (5K or greater) may only be appropriate on this engine if the majority of driving is on the highway.

That too is in keeping with Nissan's recommendations, and is also not a particularly far-fetched conclusion.
