I would personally not use anything by Amsoil in my vehicles...
Did you mean "by" or maybe "but"? It changes the meaning some.
If I am towing I assume that is severe service. I guess the EVIC doesn't know about that so we just change when EVIC says the oil is half done, or something like that?
I read that Amsoil pdf but I thought the last item, cost, was silly.
I have run Amsoil in my car in the past...
