And yet we never see members posting of their engines that went 200k, 300k, or longer exclusively on Redline oils (like StevieC does on Amsoil, or others do on other supposedly "inferior" brands). I'm not sure if that means anything negative about Redline, or that the Redline users simply don't keep vehicles long enough to reap any of the supposed "benefits" that a Group V oil provides over other oil Groups.
Meanwhile, Sally Jean uses a house brand oil from an unknown supplier with only an API cert, the cheapest e-core MIC filter, routinely travels 10k+ with 90% city driving on a synblend (at best) oil even though her manual states 7.5k OCIs normal service, does zero UOAs, and somehow this vehicle still survives 200k+ miles, or until it rusts away or is involved in a vehicular collision. Heck, she may even skip the timing belt replacement at 100k since she never floors the accelerator to save a little bit more money! Which is the better oil? They both delivered the benefits the customer expected... just one costs 2-3x more.
