Got this from a Castrol e-mail I sent:
Thank you for contacting Castrol,
Castrol Edge (SAE 0W-20, 5W-20, 5W-30, 10W-30) and Castrol Syntec (SAE
0W-20, 5W-20, 5W-30, 10W-30, 10W-40, 5W-50) currently meet ILSAC GF-5
requirements.
The first opportunity to license engine oils as ILSAC GF-5 is October 1,
2010. Castrol products meeting ILSAC-GF5 will be stated on the container or
you may refer to the API starburst oils with API SN in the donut to confirm
a product as ILSAC GF-5.
