Duramax dipstick test EXTREME™ Best Oil Filter 1Micron

Is your diesel's oil this clean? EXTREME™ Filter is the best bypass oil filter. Get soot out of your diesel's oil and keep performance. ISO Cleanliness code at 17/16/12 is between 8x and 16x CLEANER than new oil. How amazing is that? Radically cleaner oil means your engine can last up to twice as long because of radically reduced wear from contaminants like soot, because the soot is gone! Note: Each level lower is 2x cleaner. Like amsoil but better.
