Has anyone seen a SN GF5 5W/10W-30 with a higher HT/HS than Amsoil OE/XL?

It doesnt seem like Ive seen a 3.3 HT/HS before.
 
I find it hard to believe that you could actually pass the fuel economy requirements of GF5 with a 3.3 HTHS.

It's another Amsoil "recommended for", rather than actual certification and testing.

OE and XL are actual API ILSAC Certified oils.
