Re: FJ Engine oil?
Was just reading this thread and appreciated the insight. My 2014 is just out of warranty, so I'm planning to change viscosity to either M1 5w-30 (by the case at Costco) or Amsoil 0W-30 (w online membership). I run Amsoil in the FJ diffs. I live in Eastern WA where winter temps get to below freezing and summers are 90's. FJ is a keeper, so $ is not the factor, but the Costco oil is half the price. I do my oil changes at 7500 miles. Do you see a definite way I should lean on the oil choice?
