AMSOIL recently had an independent lab test both AMSOIL Dominator Coolant Boost and Red Line Water Wetter using several ASTM tests and a small block Chevy as the test engine.

I've seen the question come up many times over the years as to whether products such as these actually help lower coolant temps. These tests conducted to ASTM standards show that both products do lower coolant temps (at least in a loaded engine where coolant fan settings are not controlling temp) for both straight water and 50/50 anti-freeze mixtures. It also answers a question I see come up in these discussions as to whether straight water is better than 50/50 mixtures for cooling - it is. Note that I'm not recommending straight water, but many track day guys do run straight water.

Also interesting is the added corrosion benefit both products provide, at least compared to those who may be using straight water.

For FYI, I run a 25% Dexcool 75% water with AMSOIL Dominator Coolant Boost in my 02 Z06 which is only used at the track.

Nice job. Not to mention dumping water at tracks is better than dumping coolant.

Any one try Evans coolants?
