There's little doubt Idemistsu is using a predominately 4cSt GP III base oil with a VI in the 120 to 135 range.
How they acheive the ultra high finished 221 VI is by using one of the new very high VI polymethacrylates (PMA) branched or star type polymer thickeners.

I'll have to see what my local mazda dealer charges for this stuff. My work has an account with them, so I'm hoping I can get it at cost, or close to it. I was contemplating eventually using the toyota 0w-20 in my scion, but this stuff looks just as good, if not better, and the dealer is a couple blocks down the road from me, much closer than the 30min. drive to my nearest toyota dealer.
Aaron, thank you for posting the VOA for this oil. Looks like a great oil with lots of molybdenum; a good choice for those of us who like that. I am extremely interested to try this myself in one of my own vehicles.

Does ANYONE know if the U.S. Mazda dealers are supposed to have/offer this stuff ON THE SHELF in their parts departments, and NOT just in bulk in the service areas??????????????????????!!!!!!!!!!!!!!!!!!!!
My local Mazda dealers have NO CLUE WHATSOEVER what I am even asking for, and do not even have the older, low moly/V.I., Mazda branded Idemitsu stuff in quart bottles anymore. 
(I guess they expect one to pay boutique oil prices for their garbage bulk oils in their oil changes?)
It is easier to find/get Sustina/Elf/Millers/etc. than to get this stuff, it seems.

There is a dealer online (in Va.) who is selling it for $6.95/qt.

Get ready to burn through this stuff if your engine isnt up to this "thin" oil. Read many,many complaints on the subaru sites on the new FB engines; I tried the Subaru oil in my honda fit (oci#1)and it drank it** like a weddng crasher at a champagne fountain.

Does anyone have even a clue as to what the NOACK is on this (and the Toy brew)??
I am going to try and find out the NOACKs for the Sustina weights.

I am sure we all understand that SOME oil slips into the combustion chambers and gets burned no matter what. With that said, I am past 6,000 miles on my FF in the Mazda. The oil level on the dipstick is still at the top dimple. I'm sure some oil is gone and/or the oil could be diluted by fuel. I have a trained nose (for spirits), but it still pretty much smells like oil and not fuel. Very unscientific, I know.
I think we will all agree, also, that there probably isn't a single oil that is going to work well for everybody.
I just put this stuff in my Honda. It's a little noisier than the Amsoil, but just by a hair. It's just more affordable than the Amsoil SS. I am not able to use the long drain capability of the Asmoil due to having the VCM engine. I don't know why that other poster was talking about the Subaru oil. . . . . maybe he misread the topic title. . .
