No offense, but I also think that you should come up with a more unique response than the duplicate answers you gave
in this thread. As far as UOAs go, I don't think they help much when there are large wear particles involved, I feel that they will sink to the pan before you can take the oil sample.
I posted here first... After you've been here a while, youll find that the same questions come up nearly every day... and people don't even make the slightest attempt to read or research the toipic a bit.
If you have big wear particles, youve got bigger issues. When you see "big" metallic particles coming off your engine, it is dead.
Again, point is, the "value proposition" argument is worthless. Unless there is a significant need for ultra-low temperature flow properties, the balanced package should provide lower wear and better overall protection. Just because something is 99% PAO or 95% POE, doesn't mean that it is the best by any stretch... And if you're looking at non-boutique oils (i.e. oils you can buy at wal-mart), which have to meet a price point, you truly are better off with a balanced package than trying to offer you the end-all, be-all basestock (which you more than likely will NOT use the benefits of the basestock), with a junky add pack.
The oil industry, and in particularly the HDEO industry is EXTREMELY competitive. Even if Mobil puts group III into its Delvac, you can be sure that they will make every move necessary to ensure it stays the industry standard. If there is a reason to put group III into delvac 1, which isnt't really a wal-mart oil, and is always sold at a premium from what I've seen, you can be pretty sure that there is a reason, and it is to best something that shell or chevron has done, in order for mobil to retain industry leadership.
