Question water wetter/coolant additive

Anyone use the 'water wetter'/coolant additives made my Redline, Royal Purple, etc???

First I am curious to see if they really work as advertised and second, I would like to see if the temp drop is useful.

Both companies claim 20 deg F drops

Thanks

The cooler temperature (if actually attained) would decrease your gas mileage considerably, and would make your a/f mixture rather rich. The problem is that the colling on your engine has already very well done. The thermostat will keep you up to the correct temperature. It will just stay closed more and take longer to warm up. That is of course, if it works.

What cavymeister said is true to a point. What water wetter does is break the surface tension of water. Using wetter will help the coolant work better. The cooling system is good in our cars and we do not have a big problem. Will you notice a difference yes it will take longer for you car to get to operating temp. It will not change the a/f ratio. It does not work that well.

In V8 domestics this stuff works great. My Mustang and Cougar would run hot at the track and water wetter helped a lot. Does it work YES do we need it NO.

If you have upgrades and are running hot then you could be helped by wetter. By breaking the surface tension more of the water comes in contact with engine parts so it absorbs more heat. I use it on my stock WRX it does not hurt.

Actually Water Wetter works very well. Your gas millage does not drop, and no it doesn't take noticably longer to warm up. The lower engine temperatures would yeild more power. although it is debateable that you could feel the difference. I run water wetter in all my vehicles. On my bike which has a digital temp guage it registered a average 10 degree temp drop. By this I mean that while driving through traffic instead of the bike peaking at 230F it would never get above 220F on hot days.

If you go to the track you will be required to switch, that is why I started running it on my bike. Once I switched I liked it so much that I use it all the time now.

Default cool...literally

Well it sounds as if the stuff works like it is supposed to. My mods do not require it at this time, however I may try it out to see if there really is a real world difference. As a bonus, water wetter is supposed to work against corrosion in the coolant system.

ive used it. It does work wonders on cars that heat up too much. I would say that it will only make the cooling system more efficient. The thermostat will open at a certain temp, so the car will reach normal operating temp, but will cool more efficiently. I have a bottle and havent used it on my wrx since its winter here.

Water wetter definitely works - can't confirm it for cars, personally, but I use it on my PC cooling systems Notice a VERY nice temp drop, and fights corrosion and biological growth.

I use it in my Cruiser. It works well to keep a 32 year old cooling system cool

WaterWetter works. As has been said, your thermostat controls the tempurature so your car will not run any cooler. What it will do is allow your car to cool faster. I've used it in all my cars. If you have a car that runs hot, then the water wetter will allow it to cool down faster. In essance, it makes water wetter. It alows it to soak into the metal easier. It is cheap insurance for your cooling system and with cooling, every little bit helps.

Water Wetter did wonders to me. I used to own a Supercharged (G60) VW and I'd get very high engine and oil temps if driven at high speed. Although used in the engine coolant, I saw the oil temp drop from 260 F to 230 F due to better cooling. Sure worked for me.

If you're really hard core, you can run water wetter and distilled water. I do this in my motorcycle during the summer. However, it provides no protection against freezing, so you have to swap it out in cold climates for winter.

The only reason you would need a lower temp thermostat is that you were running hot to begin with. if that is the case then, you have to look at why that is. As far as running water wetter goes, use it. It can't hurt anything and can only help. Also, using waterwetter and distilled water is required by some organizations because if you blow a hose on the track, coolant can get very slippery.
