What brand/type of antifreeze is recommended these days?
 
I just use the 50/50 Preston mix. No issue here in North GA. And gives some corrosion protection and lowers boiling temp.
 
50/50 pre-mix is a rip off. What's wrong with a gallon of concentrate , mixed with a gallon of water ? JMO

There is one small advantage, and I'm not saying this makes the price justified...........and that is "some places" the tap water is SO bad you really should not use it in a cooling system. My years in the Navy in San Diego comes to mind.......
 
Much depends on the climate you drive in. Out here with mild weather, one gallon of anti-freeze and the rest water works. As for water, if this is a issue, some use distilled water. Remember that the presence of anti-freeze not only lowers the freezing point but also raises the boiling point.
 
I usually use traditional prestone and mix it 50/50 with distilled water. I was curious to what others have been using. Thanks to everybody that responded.
 
I use universal long life coolant. Compatable with everything.
De-mineralized water. This advice from an ancient mopar parts guy.

On a side note, the pretty pink mopar long life coolant leaves behind a silicate buildup that absolutely plugs rad cooling tubes. I stay away from that stuff.

Depends on what your system is. Soldered copper radiator and heater cores will do best with 'conventional' anti-freeze. By 'conventional' I mean the traditional green with inorganic inhibitors. Hybrid inorganic acid technology (HOAT), often green-yellow, is compatible but generally not as good in protecting solder. They also take longer to become effective in making a corrosion resistant barrier.
 
some use distilled water.
I used the green with well water for the Duster. I did change antifreeze in a my newer Mopars last year that use G-05. I did use distilled as recommended in them.

My grand mother had a dairy, the water was so hard down there u could almost walk on it. I use tap water here, which is pretty good water, but I have double filters anyway.
I can not see paying for someone else to mix it half and half and charging twice as much for it !

Why use 50/50 mix??? Do you like paying $6 per gallon for water????

Buy it straight and mix it 50/50 yourself and you will save $$$$...

How much would two gallons of 50/50 mix cost compared to one gallon of straight antifreeze???? They will both make the same amount when you mix the straight one with water yourself...
 
I have just learned that Evans waterless coolant is now accepted in NHRA competition instead of plain water . this is a hugh benefit to folks who have street driven race cars as well as dedicated race cars that spent a lot of down time . A big bene to seasonal vehicles as well .
 
Does Evans waterless coolant offer freeze protection?

Cool. I use Evans. No reason not to.

All flavors?
 
------COST !!!!!!!!!! --
-- Yep !! -- Near $50 per gallon, plus the PITA of prep, at Around $25 per gallon. --- And -- Who cares about boiling at 375 degrees. Your motor will cook long before that. -- Who needs minus 40 degree protection ? -- Zero pressure can mask leak problems, warped heads etc. -- Antifreeze with 50% water (minus 34 degree protection) and a bottle of water pump lube does the job quite well.

I use the green stuff that mixes with anything, 50/50 mix with concentrate and tap water. There's guys in my area that use pure tap water in the summer
 
Evan's orginal version is/was very viscous at ambient temperatures. You'ld still want a block heater in cold climates. The main advantages were that a) potentially higher compression could be implemented without pre-ignition b) propylene glycol based so less hazardoes c) was supposed to be equally effective without using pressure to raise the boiling point. Disadvantages were the viscosity, cost, need to keep moisture out of the system. It was a huge PIA if needed to refill or even top off and you didn't have extra with you. Now they offer several different versions but I've lost interest in their products for my own use.

I think I bought 50/50 twice. First time I didn't realize there was such a thing and grabbed it by mistake. Other time for convenience while traveling on vacation.
