Oil test results on 240,000 mile engine
 

Got my sample back today, here it is!!!!!
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!"

that is awesome haha

Good stuff..

Awesome. !

:driving:

What great news CT !!
We see that Molybenum (571) PPM is a little above universal average but this is a great Report !!
Thank you CT
Worth noting.........

Molybdenum is a valuable alloying agent, as it contributes to the harden-ability and toughness of quenched and tempered steels. It also improves the strength of steel at high temperatures. Molybdenum is used in alloys, electrodes and catalysts.

Bring on those KM !!

Gotta love a PGM-FI non-DI NA engine

What kind of engine oil have you been running?

Been running 5w30 Redline.

wow 7500 oil change intervals? awesome i baby my nismo to much -_-

7500kms, not miles...

Awesome that your engine is still going strong but man you drive too much. Lol

Timing chain service or replaced in between?
Any other major maintenance items?

Thanks

no on the chain. there has been a few things...check out my problems after 200,000 miles.

What do you mean check out my problems after 200k? Is there a thread I'm missing?

Phenomenal info here!
