Everybody mentions Mobil 1 as the magic elixir, but has anybody had similar results with another true synthetic such as Amsoil or Redline. I run Amsoil in my truck and am probably going to switch the SDL over to it at the next change. I haven't heard much about it helping with lifters, so I wondered if there was any pool of experience out there.
