0w-40 might work for street driven cars but I'd never do it on a car that sees track time.

Honestly, I'm ok with the rod bearings being the weak point. The article even says that rods, wrist pins, cylinder walls and pistons require expensive parts and engine removal. If you "fix" the rod bearing problem, you might create an even bigger problem. All of these engine tuners never really mention what the next weak point is after you "fix" the rod bearings.
Is this reply for real?

0W40 causing limp mode???? If anything the thinner oil will run cooler due to the lower viscosity being easier to pump!

Fixing the rod bearings isn't going to cause more problems! How is that possible?

This reply is totally off the wall and makes no sense. Please elaborate and tell us your thought process behind these comments!
