I am genuinely curious is Amsoil or any boutique oil worth it? Will they keep wear down? Do they last longer or do anything better? Obviously Amsoil and other boutique oils are good products but are they better enough to be worth it? or even better at all? I consider store bought synthetics to be decent such as Mobil, pennzoil etc. So I am curious how top tier oils stack up? I have considered an amsoil membership which prompted me to ask this question.
