Since it doesn't vapourize, therefore doesn't create extra pressure in the cooling system like standard coolant does when it overheats. I've used it for a long time, for example when I bought my 2014 450 exc I put it in that. I haven't needed to top it up, change it or otherwise mess with it since, a nd that bike has been raced, rallied, raced in dunes, used for offroad trips, etc etc. Like Skygod, I'll always use it no matter what. btw, utter nonsense that the engine runs hotter with it, it doesn't. We've tested with probes both here and desert use.Seminole wrote: ↑Thu Oct 19, 2017 10:46 am Evans waterless is slightly less efficient than a glycol water mix and your engine will run slightly hotter, the advantage or it is it will not boil off untill it hits a silly temperature, so you are far less likely to lose your coolant through the vent hose if you overheat.
Some Americans swear by it and if you are planning trips across uninhabited deserts it could be good insurance, here in the UK absolutely no point. I have come across one rotax 912 engine using it as the pilot had fallen for the myth that it afforded greater cooling
You really are a cockwomble mike
