saw an add for this on t v. anyone used it as has a life of 20 years, is biodegradeable,does not leave hot spots, will not boil to 190 degrees centigrade.expensive yes but is it good.
Google up 'Liquid Intelligence'. Same stuff, Aussie made, lasts forever and cheaper. http://liquidintelligence.com.au/
Have heard of this one, few years ago a fellow was heading out into the inland of Australia on his KTM, he bought the product and had my mechanic flush and fill his bike with it. From memory it raises the boiling point even higher.
Have this in a few bikes now and it doesn't find leaks like coolant does, nor does it corrode when sitting for long periods. Bikes seem to run cooler on the gauges too.
