Evans NPG+ coolant
My second-hand microlight, Rotax 912-powered, came with Evans NPG+ coolant. As I read the internet, this is good stuff, especially in hot climates, but I find it very expensive.
I should like to switch to the usual water + glycol. The Rotax engine can certainly stand that, but of course I have to check with the manufacturer if the rest of the cooling system can work on water plus glycol too.
Meanwhile I should be glad for opinions: is the Evans stuff worth its price? for someone who can't stand hot weather anyway, and is therefore unlikely to venture into hot climates?
