You say that running cold "causes greater ring wear and a host of other
problems."
If this is indeed the case then this would be a good reason to NOT use the
Red Line Water Wetter product to lower temperature. Anyone with Red Line's
Water Wetter experience have any suggestions to the contrary? Manufacturer
claims that the product can be used to provide rust and corrosion protection
in plain water for racing engines. So would it provide similar protection in
our systems with coolant?
The product label says it reduces temperature with a 50/50 coolant mix by 8
degrees. Would running only 8 degrees lower cause the engine to run rich?
And thus wash down the cylinder walls (of oil) causing greater ring wear and
a host of other problems?
One earlier reply to my query was that the engine (well maintained) runs
perfectly well without "red line's water wetter" even while crossing the
desert using the AC and that adding Water Wetter is not necessary.
I always thought running cooler was a good thing, but then these VW systems
are so new to me that I just am not convinced of anything yet.
Any informed advice anyone?
