I have 137,588 miles on my 2000 4runner Limited 4x4 and have been running Amsoil 5w30XL or 0w30 and my vehicles been running just as good or better then when I bought it at 63,000 miles. The week I bought the 4runner I ran a Amsoil flush then filled with 5w30xl and changed the spark plugs to the Denso Iridium version of the OEM Denso plugs. I just looked at my oil today with 11,435 miles and it's a semi clear light brown color, I am changing it out later this week along with the fuel filter. Mobil is cheaper but atleast with Amsoil you are supporting a American family owned company
