Hmmm. Wonder if part of the difference was due to the high temp weight.
I need to do some more research...

Yeah, except the wear characteristics from that data set for RL weren't very good...
It's not
just about warm fuzzies... honestly, I would have never thought based on my gut that Castrol or Quakerstate would outperform Mobil 1.
To the best of my knowledge, so long as you are operating the motor within the tolerances of the lubricant, you shouldn't see
vastly greater wear between two otherwise identical road cars with similar mileage -- we aren't making comparisons between DD's and track only vehicles that might be repeatedly pushed to the limit of mechanical tolerances, and even torn down at the end of a race.
Probably the biggest difference would be air and oil filtration quality.
Even if we take that data with a pinch of salt, I'll trust a pinch of salt over warm fuzzies any day.
AK's wear data for Redline is promising, but the lead wear was obscured, so I am still unclear on that. Not suggesting he was deliberately making it hard to read or anything -- I'm sure it was just accidental as you can barely make out the top, but I can't tell if that value is "0" or "9".
Anyone else gotten Blackstone analyses for Redline?
I'm not trying to stir the pot -- I'm trying to make a decision based on empirical data rather than vague feelings located somewhere in my viscera...
