There are several equivalents...

I use it in every car I own, and run about 20% Anti-Freeze/80% DI water.

The reason DI may be used in a particular industry may have more to do with costs of maintaining its processing equipment rather than its superiority over an alternative. Oversimplification here, but it would be less costly to have a HVAC tech change a deionizing filter, than paying for a dedicated crew to maintain a distillation boiler.

I don’t use deionized water for a few reasons. For one, it is an aggressive solvent and although the block and radiator core may be able to tolerate exposure, welds or connectors/fittings may contain impurities that will be compromised, deionized water also leaches chlorides from most plastics. Both Water Wetter and most coolants have oxidation inhibitors that will negate most of the possible negative aspects of deionized water. Distilled water does retain some ions and in that regard may be less optimum (mineral deposits), but organic/non-ionic components are also removed and it is less aggressive on plastics. Whatever your choice, regular coolant changes will minimize possible negative impact from either, just don’t use tap water in any case other than an emergency.

For efficient cooling, water without coolant works very well, Water Wetter improves the efficiency plus adds oxidation inhibitors.

 

Jason if your car was running fine without it & not overheating I don't see a need for it. Being in Texas I'm sure the cooling system in your MINI is working harder than the one in mine. My advice would be once you replace the water pump put fresh coolant in & see how it goes. Add water wetter if you need it.

Jason what you've said here ^ makes sense. How common are water pump failures on R56's?

 

This stuff worked very well in my old Alfa racers, and also in the tow vehicles. I add it to the MINI as insurance for those 100+ degree days.

 

Same here. Used currently!

Been using Water Wetter or the Royal Purple equivalent for years. No scientific proof it works. I think it is more habit now than anything else. The science behind the product makes sense to me.

 

DI water - Deionized Water

Available at pretty much any drug store. I get mine at CVS only because it is closer than Walgreens.

 

I have been using REDLINE water wetter in every water cooled engine I own. In the MINI I use it with water only. I believe reading the recommendation antifreeze and other agents at any percentage diminishes the effectiveness of the water wetter product.

The reduction of less than the 50/50 mix of water to antifreeze may be be done depending on the protection you wish to have within the temperature environment you live in. In some cases 10%(- /+) antifreeze for rust protection may be of benefit.

 

On the track or autocross in the summer, distilled water and Water Wetter. For street use year-round in South Texas, 1/3rd phosphate & nitrite free coolant to 2/3rds distilled water.

 

To add voice, I greatly prefer distilled water as well. Cheap, easy on the metal parts of the engine, and available just about anywhere.

 

So would using this kind if product be a good idea for an older DD? Which for me is a spirited street motored 03 MC, 105K miles, with a rad that's got about 20K miles on it.

I am surprised at the use of deionized water.

At my day job we use a lot of it, and we call it "hungry" water, as it will eat up most any thing metal.

Brass - galvanized - steel fittings are eaten quickly. Stainless will last a lot longer, but if we want to stay we use "plastic" fittings wherever possible.

 

I understand why there is pushback on DI water as it is so pure and quite the solvent. However, once coolant and water wetter is added doesn't that fill in the "holes", so to speak and render DI less reactive?

 

So is DI used because it has less stuff in it than distilled water does? Then the WW keeps it from eating things.

As found in Wikipidia;

Deionized water, however, is inherently acidic and contaminants such as copper, dust, stainless and carbon steel and many other common materials rapidly supply ions thus re-ionizing deionized water. The very lack of ions make deionized water unusually corrosive and one of the most aggressive solvents known.
