I do see where this test could prove some points and where it can also use a bit more re-testing. Due to the fact that this device they used doesn't generate the same amount of heat that an engine block would or a differential, some of the facts they proved were not 100% true b/c they didn't add in a temperature factor. Cooler air has more oxygen in it correct? Correct. So, if these machines are run at room temperatures or basically, any temperature below standard engine operating temperature, they are flawed. As the oil is heated up throughout the block, any air trapped within the oil or the block itself is evaporated/disintegrated into it's molecules. With the constant heat found within the engine block, I would suspect that the air bubbles found in this test would be very minimal in a real engine block or differential test. But, I do see how this test can have some validity in just presenting numbers, but not as much in a real life test. Your thoughts?
