Okay, I just got the following reply from Castrol, in reference to my request that I sent to them on June !:
"If you are looking for a National Distributor of this product, Castrol
would recommend an on-line distributor of our Motorcycle products called
proformance motorsports. Proformance recently began carrying some of
our automotive line of products including the Castrol SYNTEC 5W-40
grade. Please visit their website at www.proformanceusa.com
Thank you for contacting Castrol, The Technology Leader!

I checked their prices at Proformance: $7:15/Qt, presumably plus shipping. You could buy the European brands for that price. I'm a bit disappointed that they're not stocking through any of the national chains like NAPA, Advance or Auto Zone.
I recently sent an e-mail to Valvoline requesting that they update their website to show the latest improvements to their 5w-40 Synpower. It now meets ACEA A3/A4/B4, ILSAC GF-3, and API SL, according to changes on the product label and box stickers. Looks like I'm stickin' with Valvoline at $4.29/Qt from NAPA, at 60% of the price!
