Brek in period of new engines and synthetics

Just got off the phone with Redline Oil Company.  I got an e mail to the
effect that the guy who answers technical e mails is out until the 28th
of this month and I should call.  They told me that the consensus on the
list is correct.  Use a petroleum based oil during break in to seat the
rings quicker and properly and then switch to synthetic.
