Re: switching back to reg oil ?
You need to do some basic troubleshooting first. Is the oil maybe getting sucked in through the pcv valve ? Intake gaskets ? Etc.
I have done several engines with synthetic oil in them from the get go. Not an issue if the cylinder walls were finished properly. Especially if it was started and broken in on the dyno.
