This is a factory replacement engine VG33ER (supercharged)that has been carefully broken in with short OCI. The most recent oil analysis showed a mysterious spike in lead. I have used no additives and only premium fuel as this supercharged engine calls for.
This engine is a warranty replacement engine from Nissan(brand new crate motor, not a rebuild from the core bank) with currently less than 10,000 miles on it since it was installed. Nissan was reluctant to replace it but did due to a bad rod bearing at 48,000 miles.
I am concerned with the high lead levels that I am going to be faced with another rod bearing issue soon.
This truck has been babied.
What do you think about the lead levels? High enough to be concerned?
Also what about the oil, would Mobil1 5w-30 be a better choice?
