I've been using Pennzoil for years. I found this product at Home Depot for $10 less than I've paid at the local auto parts stores. Great product at a great price, thank you Home Depot.

2008 Police Crown Vic, Less top end noise at start
I have used Pennzoil on and off most of my life. Was always my go to 30W lawn mower oil but after buying a Dodge Hellcat that uses the super premium Pennzoil synthetic I have become more and more of a fan. I recently purchased a used 08 Police Crown Vic with 140K miles. Was fleet serviced every 4-5K with records and the engine inside is still very clean, I don not know what oil was used prior to my purchase but it was changed as per spec. I had a dealer do my first oil change with recommended weight Synthetic blend Ford brand oil 5-20. Now 3K miles later I change to this tried and true Pennzoil conventional 5-20 oil and I notice the normal start up top end rattle noise is gone to almost gone. Strange, to actually hear a difference in a engine based on brand of oil surprised me after 40+ years of changing my oil especially moving from a blend to full conventional oil on a high mile engine. I remember my late father telling me back in the early 70's to always use a good Pennsylvania grade motor oil... Father recommended, Dad approved!
