Yes, you can go to the API website and see that the Amsoil XL line IS fully API (SM) Licensed and Energy Conserving; it has been API Licensed at least since 2002.
And although many other products on the market can go 7,500-miles/6-months, the Amsoil XL line is the only product I've seen marketed to quick lube shops to claim as such.
For example, I talked to a well known national quick lube chain that offers Pennzoil Platinum (PP) as their synthetic motor oil change. I asked them what they recommended for an Oil Change Interval and they said 3,000-miles/3-months. Then after talking with them further about UOA reports and current oil technology, they conceded that the PP was good for 5,000-miles but that corporate would not allow them to tell the customers that.
Big oil and quick lubes love the 3,000-mile OCI.
