Does anyone know if Pennzoil SAE 5W-30 oil with API Service SN can be used in place of the original SAE 5W-30 oil with API Service SF/CC in a 1988 Corvette?

As far as I know Pennzoil can be used in anything. Look on their website and it will tell you everything you need to know. I believe the new oils are better than the old ones.

Been using Pennzoil in my 88 for a long time. No issues.

Like russ1953 said, the answer is yes regardless of brand of oil.
