Like I said, it's more than twice as expensive so, in the above example (1 change with Amsoil vs. 2 with Mobil 1 & Motorcraft filter), it is in no way cheaper over the year.
If I can go for much longer w/o crawling under the car, that makes sense to me. My time is actually quite valuable to me. So, 1 Amsoil change in the same interval as 2 M1 changes equates to less time on my back. There is value to be had there alone.
