i personally would, to get more of the crap inside out...

personally dont recommend using a flush of any kind. It can displace carbon or gunk and lodge it elsewhere that maybe detrimental to your engine. Just change the oil every 5,000ks and filter every 5-10,000ks , that should keep any sludge buildup clear of your engine.

PS i recommend honda FEO for all honda engines.
