His observations don’t translate into use WHAT SO EVER so doing oil show downs and brackets is super annoying. Even more annoying is Amsoil using that nonsense as advertising material. For example his bearing test has been shown useless in an engine application and his cold “flow” test have shown to be useless in cold “pump” ability. He just tallied up additive count with disregard to balance, type or effectiveness and whichever had the most was scored better. Yet he spent WEEKS bracketing oils based on this nonsense AND declaring a winner. I’d say that’s a little more than observation. He does do some useful testing but OIL is not one of them. He doesn’t have the equipment, money, time or knowledge to present rankings the way he did. He might have the money the way that was eaten up lol.
