Shock Chemistry is in your oil for 5 to 10 minutes than you drain it (this is a flush) it removes some contaminants maybe in pieces that may or may not get caught in the oil pick up screen or a piston port. During the 5 to 10 minutes it is in your oil you have thinned out your oil viscosity affecting your oil's ability to lubricate your engine.
Auto-Rx liquifies the internal contaminants and drives them to the filter. ( Auto-Rx uses the oil as a carrier) we increase the lubrication of the host oil as we "clean" the internal parts.
Auto-Rx does "not" change the chemistry of your oil during its cleaning or rinsing there are no pieces to clog up an oil screen or a piston port.
When you drain your oil not every thing leaves the pan it makes no difference if its solvent chemistry or Auto-Rx. Which would you rather have in your new oil ?
