Just purchased a 5 qt jug of 5w30 SM/GF4 Supertech at Walmart. Curious,I couldn't wait to see what it smelled like... To me it smells exlactly like the shortly available Mobil Drive Clean SM/GF4 stuff that I have stored in my cache. By that I mean the identical same laundry detergent type smell. Does this mean they are similar in additave pack or maybe even the same blend? Also I have read that it is impossible to blend SM/GF4 in 5w30 without significant group II and/or group III content. Is the detergent smell a charateristic of the new antimony additives? This oil was being sold alongside of the GF3 stuff at the same price(under $5.00)!

In the link you provided there's another link to a place on Chevron's site: http://chevron.com/prodserv/BaseOils/gf4_faq.shtml
"Group III+: Not available yet commercially. These will be available in the second half of this decade made from gas to liquid processes. They will have VI's exceeding 140 and will be used for 0W-XX and 5W-XX engine oils and super-premium transmission fluids."
Group III+. Sounds interesting, but why not just use PAO? Does PAO cost that much more than Group III oils (including Group III+) to produce??
Further down the page, it mentions this:
What about 10W-30? For GF-4, can it still be made with Group I base oils? What are Correction Fluids?
Most Group I base oils cannot be used for GF-4 10W-30 without some help. Higher VI base oils, called correction fluids, can provide this help. Depending on the properties of the Group I oil used, the final blend might require 10-50% of a correction fluid, such as 5R. If a Group III correction fluid is used, less will be required."
Didn't Carpy describe some new Mobil and SuperTech products that were to be formulated nearly identically to the above quote from Chevron's site?? Carpy is either a prophet, or a guy who knows his stuff!

Isn't the new Pennzoil Platnium a blend ofGroup III+ and PAO?
Exxon/Mobil is the current supplier of SuperTech in parts of the Northeast--it's very likely the exact same oil in a different package at a great price--snap it up!
