AMSOIL oil and filter change intervals for vehicles in warranty can be found at http://www.amsoil.com/lit/g1490.pdf?zo=1181889 . Several new car dealerships offer AMSOIL for their cars under warranty.
Sure they recommend their XL series API certified oils, and to follow the mfg OCI, not Amsoil extended drain intervals. Telling someone to use Amsoil for 15K without a change in a new $90,000 motorhome is poor advise.
If you have a new car, it is wise to follow the OCI in the owner's manual,because during the 1st 25,000 to 50,000 miles on a new engine is where you are going to have most of your break in wear.
No oil filter, not even the Amsoil EaO Oil Filter is going to trap all of that break in wear material, some of it is going to be dispersed and held by the motor oil.
