You do realize that the XL7500 is the low end of the Amsoil line? It is made with Group III stock rather than the preferred Group IV pure synthetic stock that Mobil1 and the more expensive Amsoil oils are made of.

XL7500 used to be made with the same pure synthetic base stock as the rest of the Amsoil line but, they changed the formula a few years ago to try and create a less expensive entry level oil.

The 7500 in the name stands for the change interval. It is recommended that you change it at 7500 miles rather than the higher change intervals of the more expensive oils in the Amsoil line.

Here is a link that you can look at (scroll about 2/3 down the page)
