With all of the testing done by SAE and API to insure that oil meets these INDUSTRY WRITTEN standards I can't believe any oil manufacturer can actually PROVE their product is "vastly superior" to any other product that meets the same specs.
And I used to be a Mobil 1 ONLY guy for many years !
Where pure synthetics shine is in extreme cold temps, like -20F ! Amazing how fast a engine will crank with synthetic oil at that temp !
API Charges an oil company to be "certified". Amzoil for years was never API certified.
There was (is?) a snake oil salesman in OH that was selling his custom blended oil. A few of us figured out exactly what he was selling through individual conversations. He was buying penzoil full synthetic, adding a moly product, and selling it as a product that changed the molecular structure of the engine. He was good, really really good :)
