I do have one last question. How long should I run break in oil? I've heard about O2 sensors going bad from the high zinc content. After the half hour under 2000 rpms what the length of a normal break in period?

 

I would just go to your next oil change. And with the RPM's you will have no problem after the under 2000rpm time passes. I would say maybe go with a few hundred miles, than change the oil and you will be ready to rock and roll.
