No, your presumptions are not correct.
I have other cars that I have passion for that I maintain extremely meticulously, but that is time consuming. Oil Undercoating annually, car washes and wax regularly, top tier Amsoil oil filters, and proactive driving habits to reduce wear and tear.
I do those things because I trust those cars are reliable and will last a while. The Nissan? I don’t know if fastidious maintenance will do any good with this infamous CVT, that’s why I am asking forums, not gloating about wanting to destroy something. I don’t want to waste my time on a grenade.
I already said in my OP that I was thinking 7k oil changes, cheap filters, and no oil undercoating. Those are examples.
