has anyone used this "water-wetter" from Redline?

[SharkmanBMW]

I am going to place an order with Bruno at Racing King for some Redline fluids...

just want to know if this is worth anything?!

It is mostly for race applications where anti-freeze is not allowed. It has some anti-corrosive properties that is better than running straight water. Anti-freeze is slick on the track, so usually not allowed. Some say it will drop your running temps by 10-15 degrees...that is BS.

Funny this pops up... I just added a bottle of Water Wetter to my 540's reservoir. Now, when I added this I also squeezed on the upper rad hose and the level in the coolant reservoir went down a notch. Was the system not fully bled? I guess there was some air trapped in there. So it may be a coincidence, but my temp guage now reads just to the left of (but still touching) the center hash mark; whereas before it was dead-on-center. Was it the trapped air making my engine run ever so slightly normal? OR is it the Water Wetter doing it's stuff? I don't know, but it was only $8.00 at Auto Zone.

the wetter stuff is a complete waste if you use antifreeze...and the V8s self bleed, you dont have to ever bleed them.

Guys in the 944 Turbo world swore by the stuff, they are notorious for running hot (water cooled turbo). Probably not worth the money on a regular NA car.

it changes the surface tension of the coolent a little so it transfers heat better (slightly) i ran it in the bosses e30 m3 and it helped it stay in range, it won't cure a problem or work wonders but if you are on the edge it can help

I used in my Porsche 944 Turbo, and it helped to reduce temps somewhat. Not earth shattering, but maybe 10 degrees or so.

water has the best heat transfer of any fluid. period the end this is a fact.
so water wetter is only put into water to prevent rust and crap as was
said above...

adding water wetter to ur 50/50 mix is silly...just add more water

water enabling it to transfer more heat... that said it doesn't make a tremendous difference on most of the cars i've seen it used on and on some cars it can cause problems since its very alkaline and your ph on your coolant can change quite a bit depending on whose coolant you use and what the ph is... isn't usually a problem on bmw's but it was on some of the older brass tanked soldered radiators.

It has also worked for me on a Ferrari that had marginal cooling.
