Can this be mixed with tap water or is distilled water necessary?

De ionised water is the best bet. Tap water especially hard has minerals that after a while can clog your radiator

can you mix the speed flush in the system with new coolant for long period

This item is for flushing the system, not for mixing like radweld

Is it possible to flush out 100% of liquid? if not is it ok to have a small amount of holts cleaner left in the cooling system? thanks!

Hi, how much you get out is dependant on the cooling system design, but you can just keep running water through until it's clear. A small amount left shouldn't affect the new coolant.

How good is this removing oil from the coolant ?
