just curious what is so much better about the toyota stuff ? does toyota have a lifetime gaurantee ?Toyo said:Comments? No, dont even try it. I would use only 2 types of coolant in this bike. Original Honda or go to a Toyota dealer and buy some of thiers. It is already prediluted with distilled water for you or you can buy it straight. Great stuff. Thats what is in mine. Been all the way to Southern Arizona in the summer to southern Florida.
