Anyone have a Pennzoil Conventional 5w20 VOA hidden away somewhere, or willing to get one for the greater good? Simply curious because our 03 Expy 4.6 is getting changed to Motorcraft Semi-syn 5W-20 tomorrow, and it's been 5500 miles on a Pennzoil conventional Bulk 5W-20/Fram filter OCI (Hoffman/jiffy lube).
