I beleive that since the oil companys need to change the artwork on their bottles in order to show that their product meets the new SN/GF-5 spec, they may also want to change other wording and labeling as well. Some companys may only change minor wording but, if contracts are ending with, whom ever does the bottle printing/artwork and the current labeling has served/outlived it's purpose, the oil companys may want to change the whole look of the "NEW" product with a redesign and add in some choice wording such as "Tri-Shield" or as with with laundry soap...New & Improved! They don't always tell ya what is "NEW" or "TRI" about the product.
