Trent-> I read that and I am currently using rmi-25 and coolant. But it has not been changed for two years/ 7k miles. I plan on going with the NPG+ since after reading the information it made a lot of sense. I liked the fact that if my head gasket blew the NPG+ will not destroy my internal parts.
If anyone out there can prove otherwise, or has tryed the NPG+ with no positive effects please feel free to let me and others know. That way I can save a buck.
