NEITHER!!!
might as well pour some diet pepsi in.
if you are going to pick something from autozone, pick Shell Rotella T 15w40 or Chevron Delo 400 15w40 or Mobil Delvac 1300 15w40 or Exxon Superflo 20w50 (during summer).
now, if you want to spend the money and have an awesome winter oil, get the Castrol Syntec 0w30 that says made in germany on the back.
