OK, being a devil's advocate but also asking a serious question: Does anyone really think you would have an oil related failure in 150,000 or more miles whether you use Mobil 1, Pennzoil, Redline, Royal Purple or Amsoil - as long as you use a quality filter and change the oil based on your driving habits? I am not talking about 150,000 easy miles, either. I am talking about the way we drive our cars, including a few trips to the drag way.
Blackstone results and Oil statistics are interesting but does it really matter? Is there anything to be gained in the long run by spending twice as much or more for oil? I am talking about the differences between well-known brand synthetics. I am NOT talking about conventional no-brand oils.
