I think there is in fact a "best oil" ... However, it's all dependent on the application, driver, climate, traffic, etc... and these are never the same. There's too many variables for there to be one specific best oil. You have to do some trial and error to find the best oil for your situation.
That LS430 will do that speed (149 listed as top speed that I found, limited) and would have tires etc. all able to handle it with no drama - Tirerack shows the 17s (assumption) are H/V/W rated which would be 130+ and fine at that speed. Now whether you should or not from a risk perspective, who am I to say? I find it hard to believe that you could drive that fast sustained many places in the U.S. but that's not what he said - "4 hours plus at 130 on trips at times" - more likely meant "4 hour trips and I hit 130 once in a while" is how I read it.
I can tell you, when we were deep in the COVID quarantine here, the roads were absolutely empty...like apocalyptically empty. My car has been upgraded substantially for performance, handling, and braking. I was able to YOLO an all-time top speed on the highway one night on a nice long stretch...140mph. It was fun but not something I would do all the time. Loud and bouncy...needs to be lower and I need better dampers at that speed to slow the rebound down...they are on the list as the next upgrade. But still....I can say I went 140 for a few seconds in a Golf station wagonSome people definitely do it. Just look how many new Cannonball records were set back when traffic was light a few weeks ago. Some big tank cars had averages over 130 mph in some states even without pilot cars.
