Oil sample
 

I forgot to mention to blackstone I was low on oil. We will see on the next sample if aluminum is still high

Was the aluminum level high before? What motor oil and oil filter are you using?

When I was using amsoil racing oil. I’m using motul ester 5w-40

I'll post my chart & let you compare; though my Z is gone.
I used ethanol free 93 octane fuel & it said my lead was high/as if i had run some leaded racing fuel.

According to Nissan the best choice is to run a ester enriched motor oil like Motul or Redline etc. with a quality oil filter preferably with synthetic media. It also matters what fuel you are using? Using only a top tier gasoline is highly recommended by Nissan. When I found this out I started using top tier Chevron and Texaco as soon as possible. It seems you will find a lot of the gasoline companies have mixed a percent of ethanol in their gasoline’s.

I agree. It mainly gets shell v power

I've had great results using Castrol Edge Titanium 5w30. I bought the car with 60,000 miles and have been using that since. I did switch to Mobil1 0w40 on this current interval. I'll see how the two compare when I get this oil change sample report.

Your oil sample report looks pretty good. I would stick with 5W30 though. Even though you could pull it off with Mobil 1 or Castrol synthetic motor oil I would never recommend going 8500 miles between oil changes. I would change my motor oil more frequently like every 4000-5000 miles if it were my VQ.

Ours looks just about the same. But our usage of oils are completely different.

Updates?

This last sample was Mobile 1 0w40 compared to my first Castrol Edge 5w30. At the moment, I am running Castrol Edge 0w40 European formula.
