The highlights...

"CHRIS: Mostly this is a good first sample from your 370Z. Considering it has nearly 400,000 km under its
belt, it makes a relatively small amount of metal. The balance of the metals is good, so we're seeing no
problems there (averages are based on a 8,300-km oil change). The only thing out of line in the spectral
exam is silicon, so check the air filtration system in case silicon is from dirt. lt could also be a harmless
sealer. The viscosity is mildly thick; that could be from heat on the oil, or maybe an additive was used that
thickened it up. lnsolubles look good. Overall, nice enqine!"
