I switched to it after reading about the csr cars at rpm technik . It’s supposed to reduce hot spots reducing the risk of bore scoring . I like that it pretty much eliminates corrosion . I installed a new water pump and low temp thermostat at the same time

i liked it enough I run it in all my motorcycles

my brother has a vw Westphalia with a water boxer engine which are notorious for corrosion in the system killing the heads ( that’s why we had to rebuild) so we used it after we rebuilt the engine
