Just saying, if you were looking for excuses to upgrade (no, i don't have one to sell)  |
Yeah I heard the ball bearing turbos don't last as long though, so there is a bit of a trade off there..

I'm sure it's fine for everyday grocery getters but you would catch me with that in any performance turbo motor. Hell I use Walmart oil in my truck and it has 322k miles on it. Doesn't mean I would put it on my Talon or 240.
In a turbo motor you should use a turbo high in zinc.

Interesting, but I'd like to see more testing on this. Maybe the turbo experienced premature wear from the small bit of napa oil that was still in the motor from the previous two oil changes. The turbo is spinning so fast I bet that even the slightest bit of subpar oil can cause damage.
