Interesting... My personal opinion- that is somewhat deceptive advertising on their part.

Amsoil never says they are certified. How is that deceptive advertising??

I understand them not wanting to spend the money (100K I think) to do this.
Everyone just remember; if it does not have the API seal (see my first post above), it HAS NOT been tested and rated by the American Petroleum Institute. That does NOT mean the oil is inferior, it just means it has not been tested by the API labs.

I've heard very good things about Amsoil. I checked out some other oils and ultimately decided on Amsoil, mainly for the rep on their 0w-30 syn oil. How long are you running the gold GC in ur motor before you swap it out? and I have no idea what an UOA is? Im guessing it messures oil particles or something?
UOA = Used Oil Analysis

Cut and paste from the G35 Factory Service Manual:
SAE Viscosity Number ALS0006I
GASOLINE ENGINE OIL
SAE 5W-30 viscosity oil is preferred for all temperatures. SAE
10W-30 and 10W-40 viscosity oil may be used if the ambient
temperature is above -18°C(0°F)
A major auto company spends millions of dollars and untold hours developing an engine. Based on this research and development, guys in white lab coats with engineering degrees specify a oil that will maximize engine longevity and performance. Then, after spending twenty to forty thousand dollars on a G35, some think it is a good idea not to follow oil specified by Nissan. Incredible..
0w-30 Amsoil? Have fun with your science experiment. My money is on the guys in the lab coats.
Not trying to start a flame war, I am trying to make a point- Stick with with Nissan's recomendations...

Why, especially when it has better cold flow viscosity rating (0w), the same 100 degrees Celsius viscosity rating (30) when compared to 5w-30 or 10w-30 , or thinner at both ends of the spectrum when compared to 10w-40?

With what you're saying, going with 0w-30 is bad..
