Saw them both at wally world today and outside of RAT's blog showing QSUD as the best 0w20 I can't see what the diff is moving "up" two levels. Is it Ultra>Plat>QSUD? Is there anything inside the bottle that's diff or just the outside?
Oh and the exact same QSUD in a new bottle just went up in price.
