I dont know who makes the best coolant but I do know without any doubt whatsoever that plain anti-freeze isnt good enough in modern engines. I started adding DCA (dry chemical additive) to all radiators a few years ago and check some with test strips. Hopefully, this procedure will prevent problems many folks are having with pitting etc. This is another reason I like my R60 with a Deutz. Tom in MN
