I used Mobil 1 for years and never had oil related issues in any daily driver. Still use it in my truck & DD because Sams has it cheap, but they don’t carry 5-20 I need for the wife’s Pilot, so for that I use whatever is on sale at Advance Auto. IMO for regular street cars any brand name synth will be fine. With anything I think there is a bit of hype involved.
If I had cool cars like Josh that go fast and really tax the oil system I’d probably use Amsoil, Royal Purple, Mobil One or Castrol. Those seem to be the choices amongst pro racers.
