yep. mobil1 doesnt publish their NOACK values, but from what ive seen 0w-40 is in the 8-9% range. its an ok value, but its overall a great oil. i wouldnt run 0w-40 in our cars though unless you're FI'd though. its significantly thicker at operating temp versus a standard 5w/10w-30. your engine may lose some power due to the added thickness.

the thing is, my z isnt burning that much oil with the m1 5w30's.

everyones engine is different
. going purely by my own anecdotal evidence, in the last 30k miles, i havent burnt any oil. fill up at 6 quarts just to the top of the dipstick and 6k miles later, i still have the same line on the dipstick
