After looking on the Shell website and browsing through Walmart today, I noticed something. The Supertech bottles use the same color scheme as the Formula Shell. Except that Supertech has no blend.
This is Shell:
Conventional - White bottle
High Mileage Formula - Red Bottle
Synthetic Blend - Blue Bottle
Full Synthetic - Silver Bottle
This is Supertech:
No White Bottle
Conventional - Blue Bottle
High Mileage Formula - Red Bottle
Full Synthetic - Silver Bottle
Don't know if this means anything, but I thought I would just post it anyway.
