API Spec it's a good thing

Well that's fun, marketing is a strong influence on preferences. There are way more brands than there are refineries to make the oil. From Ace Hardware to Ford everyone seems to have a "Brand" an anecdotal reputation and a committed customer following. Many, like Ford, have their own spec # but it backs into and uses as a base the API spec. API has specs and grades for oils that manufactures brand. Manufacturers meet or exceed that spec and all use that API relationship as a baseline for quality.

So think of it along this path. I really like MY oil because it comes it a neat bottle and its purple, or green, or has a high tech sounding name or has a gimmick sales approach but WOULD I really actually buy it if on the back it was written "Does Not Meet API Specifications" for your engine?

It's not magic Pixie juice, it's an Engineered product. Use those man/years to your advantage and check and rely more on API Engineered specifications than brand marketing.
