KK in my vert I used every kind of Coolent you can almost think of. I even used strait water to see what the temp would be like and also water watter. Ive concluded that water wetter does NOT help as all for highway temp. If it does than you were just using the wrong coolent to begin with. I use prestone 60%/40% and that is the best soo far. Ive ran it with water wetter to see if it made any difference and got nothing. I ran strait water and between water/crappy coolent to the prestone its about 15 deg difference. ater weter is a waist of money and yes soap is the same shist ive herd too but since it makes no difference and I know my engine and rad are clean its no pint for me to use it.
Prestone FTW!!! Ohh I also baught non chemical water from home hardwear for it. HEHE
Actually, the point of water wetter isn’t lowered overall engine / water temperature. Water wetter is designed to reduce hot spots in your cylinder head. It does this by reducing the build-up of water vapor in any superheated areas. The bad thing about having hot spots in your cylinder head (read combustion chamber) is that they can promote pre-ignition - definitely a bad thing. Any sharp edges in your combustion chamber (around valve seats for example) may tend to get very hot (even red hot) during operation. These areas of the combustion chamber can then form local hot spots in the cooling passages. Thus, even though your bulk coolant temperature is well below its boiling point (i.e. your gauge reads just fine), there may be localized boiling in some regions of the coolant tract.
This localized boiling can cause a layer of water vapor to form over the hot spot. This vapor forms an insulative blanket and prevents heat from leaving this area, thus making the hot spot even worse. But reducing the surface tension of the water makes it easier for vapor bubbles to leave the surface of the cylinder head and allows the bubbles to convect heat away from the area. Something that changes the surface tension of a liquid is called a “surfactant”. It does not take very much surfactant to significantly change the surface tension of water. Hence, you do not need to add very much “Water Wetter” in order for it to do its job.
An additional benefit of using “Water Wetter” (in conjunction with 100% water) in you cooling system is that water has an extremely high heat capacity. Thus a gallon of 100% water can carry more heat away from you engine than an equivalent gallon of 50/50 water and coolant. Water also has a high thermal conductivity which increases the convection of heat away from the coolant passage walls and into the free stream of the liquid flowing through the passages.
“Water Wetter” does not increase the boiling point of water. Standard automotive coolant does increase the boiling point of the mixture above that of 100% water. But remember that if your cooling system is operating properly, it should never get hot enough to boil (I mean BOIL, not just localized boiling). Raising the boiling point of the coolant in passenger cars is primarily a safety measure, so that if the cooling system is over stressed (climbing a hill on a hot day with AC on), it will not boil over. On performance cars the primary duty of the cooling system is to keep the engine in its optimum temperature range. This is best accomplished with 100% water, because its high heat capacity makes it very efficient at transferring heat.
Performance cars often run relatively high cooling system pressures. This also raises the boiling point of the coolant. But the high system pressure is not used to avoid boiling so much as to allow the engine to operate at a higher temperature for reasons of efficiency. A higher cooling system bulk temperature also allows the use of a smaller radiator (there is a greater driving force to transfer heat from the coolant to the free stream air). Take a look at the E30 M3’s “tiny” radiator and you will see what I mean.
Thats quoted from a website but the theory is correct. Again, I don’t use water wetter because of buildups of crap I have seen it leave on the inside of cooling systems after a lot of hard use. Its kind of film like… 2 Drops of Dove hand soap will do the job just as well. Why Dove brand soap. The reason is that is has the lowest number of other additives I have found so far. Less crap = Good, I don’t really care if my coolent smells like flowers.
Well its all in the wording… Its just like when Royal Purple says that you will make more power with there oil and its engine dyno proven… Yes is does make more power during the test with royal purple… Which is complete bullshit because the reason it makes more power has nothing to do with the oil.
I accually do goto import guys to get ideas for my charger, its amazing the same technology the performance world bring with american - import cars…If you asked, what cams should i run, i could give u a very good answer, because i know what they do and specs…anyways back on topic…With a v-8 different oils will make more difference than a 4 cylinder because of friction. Royal purple has a very good additive in their oil which does create more power. And less friction obviously means less herat, which royal purple uses as a advertisment. Most of the time, if you run synthetic, you will never be able to flush it out without hot tanking the motor. But like i said before, there is oil for every application, even driving style. Dosen’t matter what car it is, it all depends on ur build and specs…
Example, you run a full out race motor with super tight clearances, your gonna need a race orientated oil, So really you have to read up on what brands have to offer, and figure out what matches you car and driving style.
Why the fuck is every one of your posts something to do with v8’s correlating to imports. Jesus christ, no one cars about you liking muscle cars and imports at the same time, good for you…fuck…WE ARE A NISSAN FORUM…WE DONT GIVE A FUCK ABOUT YOUR DRAG RACING CHARGER OR YOUR CARBEURATED V8!!!

Dude i was talking bout oil the whole time, yet u all have this mind were i think just of my car…True this is a nissan forum, and guess what, ive worked on many… Ok here my friend uses royal purple gear oil in his tranny in his skyline gts-t, works freaking amazing, thing shifts like a dream…Im making the point, domestic to import, i know very well…yeeesh…Back on the oil topic again, seeing you guys keep bringing up my car, I recommend ppl trying out royal purple brands For a performance oil…i have used redline in many cars, i feel it does not perform as well as royal purple. By the way im a mechanic, i work on a huge variety of cars, and trucks, so i have great knowledge on what oils work on certain vehicles.
And how do you supposedly know what oils “work” and what ones dont. Where is your proof or actual knowlege about these “facts”?
It’s the same thing as someone using an ass dyno to estimat they will run a 12 second pass. To say that redline oil made you spin a rod is ridiculous, you have no way of actually knowing why it happened. Odds are it would have spun if you had royal purple in it too.
Facts son…without them all your giving is your biased opinion, which is really completely uncredible, woopedy doo, your a mechanic, you work on nissans, that doesnt give you any credibility whatsoever as to why you say redline oils suck, and royal purple is good.

i didn’t say they suck, i said i have used both seen both run, on our engine dyno at our old shop, we have seen engines pull better with royal purple. I have facts to back it up, as i work for a performance shop. There is no bias, cause all we ever used was redline, till we found how well royal purple works. But like i said before, some vehicles and type of driving depict the oil. Import domestic euro, dosen’t matter, it pretty much goes on what ur engine was built for. As well as ur diff or tranny, all depends on what ppl recommend.
