Porsche 911 UOA

[Porscheman]

Hi folks, New UOA on my watercooled 911 997 Porsche year 2005

Valvoline Synpower 5W-40

6000 Miles

Total miles on the engine: 82000 miles

Little high on Nitration, should i be concerned? And what about the Viscosity? All other values seems to be fine.

Looks good to me

The KV@40*C indicates shear thinning from virgin 85 cSt, and that's normal.
TBN is high at 8.2 and superb metal wear rates.
Nitration # is normal too, I'd speculate OCI could be extended to 15,000 km or higher.
