I ran regular oil the first 1200 miles. Nissan Ester 1200 to 5000. Now I'm running Royal purple. Till I hit 10k. I might switch to redline and stay??? But for right now I'm loving Royal purple. So far it runs just as well in my engine as redline, which I've had in my G37. Castrol edge is an extremely good lower end synthetic if these are too expensive? Mobil1 is what the dealerships run and its good as well.
