-interesting link, im a visual person and im still really freakin hungover
I cant even comprehend this simple discussion kind of sad lol.
anyways.
I used to run SAE50 valvoline on my ole 62-1 car, never had a problem for about a year, than the oil pickup went saucer and threw a bearing...
If i was baller I would use turbo specific oil, very cool stuff.
Good discussion indeed.
