The weakness of your coolants is unlike oil, they have no cleaners. So when your radiator starts gelling up, you will never know until your water pump is choked off. RMI25 = Cleaner. I ran it in a vehicle that had slime buildup, that would have kept growing until my entire system was choked off, unless I ran the RMI25. Coolant damage is happening in many cars as soon as 5k miles read the links, the upper pic was 40k something. Unlike oil you wont seeing it coming until you are smashed with major damage. If you are lucky it will happen in warranty, if not that's on you. A good strategy might be wait until you have a month left in warranty and then add it, for guys not wanting to run it earlier.
