I seriously wonder.......... what would happen if you did another Amsoil flush - and then another - and then another - and then another, ad nauseum. Maybe your engine would get to the point it wasn't using any oil? I am very fortunate so far; no oil consumption, and no slipping tranny. But, I am only at 37K on my 2014. However, I am meticulous about changing oil on schedule with synthetic blend, and having the tranny serviced faithfully. And I have an AFM delete. Plus, I baby the transmission as far as shifting it hard via rapid launches, etc.
If I had it to do all over again, I'd have kept my 2003 with 230K on the clock. What a fool
