I just use oem coolant, its cool cause its blue and its oem so I just have that instant piece of mind and don't have to spend countless hours doing research to validate myself in an attempt so save a few bucks.
Honda can use any ethylene glycol coolant, (Green, blue etc). It CAN NOT run propylene glycol, (Dexcool, VW gold, etc). It will mix and create a sludge inside your cooling jackets and wreck the engine.
