Good oilBy NATHAN, a Verified Buyer from Minnesota on October 01, 2026I love using amsoil, it is the best oil I have come across. One of my vehicles, 2003 nissan 350z, the motor (VQ35DE) is known for burning oil. With amsoil, very little burns compared to other brands like mobil 1 and valvoline.Bottom LineYes, I would recommend this to a friend.Was this review helpful?
