Ahhhhh NO!!!!! Motor Flush is nothing more than kerosine. What ever gunk it doesn't break free, it will loosen. Then when you go to drive off, at some point that loosened gunk will become lodged somewhere you don't want it to. What makes you think you need to go to this extreme. Look inside your oil cap and see if there is any build up.
