I've always liked Valvoline products. NAPA brand is just rebranded Valvoline that has a very good spec sheet. Its what I've been using for years now. Always a good price and usually their synthetic can be picked up on sale often.
How does the PQIA test data help in comparing two oil's performance? It doesn't. They test the amount of additives (but not even the form of the additives and only metallic), and some very basic performance information to check against published spec sheets. All of the other component of an oil including non metallic additives along with real performance information under actual test conditions are not in the PQIA scope. People are just guessing if they are using this data to compare two oils.
