Penn Ultra 5w30 Nissan 370z VQ37VHR 6300 miles

[bvl]

Hello folks,

Second UOA for our 370z. Few other G37/Z threads out there but with various fluids. PU shaping up nicely as expected on an engine that is a bit hard on oils. I have a 1+ year stock left over though local wally world is still carrying it for now

I won't run longer then 6mo/7500 OCI while under warranty so I don't regularly grab TBN knowing its working in my interval is good enough for me.

Its good stuff...just hard to get in most parts of the country now thanks to those in charge from Bentonville,Arkansas

Get your UOA done by Polaris so you get oxidation and nitration. TBN is not the whole story. The TBN is low for your OCI (and yes I know its not linear).

Looks like its getting better with each OCI

Great report! I wouldn't expect any less from PU. This is another example of how stout of an oil PU is. That engine tends to shear other oils down by a grade(along with my EJ255). PU barely budged in viscosity. So happy I stashed up this oil.

Low TBN at that milegae. I thought that this was suppose to be PU, the long OCI oil.

TBN is not linear in it's degradation.
TBN must also be taken into context with TAN, when TBN is lower.

This lube did a good job, but it's being under-utilized.

Good run. Still breaking in.

I have a bunch of the stuff purchased from WM clearance racks (several locations)and use it in both vehicles. Even the 'ol minivan purrs like a kitten on it and uses no oil during its 5,500-6,000 mile OCI's. I calculate that I have about 2 years worth considering my driving. I'm not sure what I'll do (buy the PU at a higher price if they're still making it or switch to something else) when it runs out.

LOOKS GREAT!
The wear numbers are coming down nicely(though they weren't that High to begin with) and this OCI looks consistant with the previous OCI in the add pkg.

Silicon is lower too but, sodium and magnesium are both higher this OCI. Maybe different Lots/Batches of oil(purchaced at different times)??? Or the extra 300 miles on this OCI???

Who knows! But, still very consistant from OCI to OCI.
