IMO, if you want the Redline, just wait a week. Another 100 miles will not really make a difference, so why waste the $80. But if you really feel you need it changed now, then get it done and do the Redline next change.
The Penzoil will be just fine. I use Penzoil Ultra with a Purolator PL14610 PureONE Oil Filter in my Z.
