That seems like a really good idea! Anyone have experience with this that wants to share?

Been running the approved Mobil 1 0W-40 since I started at the track. No other cooling mods. Manual trans.
Based on responses I've read, I still was expecting my car to explode and burn down neighboring cities... instead, max oil temp = 260-270 on ~90 degree track days. I dunno.

Same thing here. Mobil 1 0W-40 and distilled water and Water Wetter in the radiator, no limp modes since these 2 mods. |

Do you track your water temps on track? Did you see a real difference in numbers with water wetter?

I always wanted to, but I always forget how to access the hidden menu to see the water temp. Water wetter is no special ingredient. Water cools down faster than antifreeze and water wetter is there only to provide enough lubrication.

I have a water temp gauge, but I don't know how I could do a valid test. I've seen reviews that seem to prove that Water Wetter in 50/50 mix reduces temps a little, and in 80/20 or 100% water reduces it more, but not by 30 degrees. Anyway, it's only $10 though some people use two bottles.

Water wetter can be added to regular 50/50 mix of water and antifreeze for enhanced cooling. |

Some articles I read on the product indicated otherwise. Most of them indicated that Water Wetter by itself doesn't help cool down the engine. Water wetter is more like an additive to the water to keep all the seals and piping lubricated. Water by itself is going to cool down faster than the coolant and that is where you will see the benefit. I don't know of anyone using the product with the coolant but I know it is compatible. I guess adding it to 50/50 mix just makes it 40/60, so partial benefit might be there.

Obviously you are going to get a larger temperature drop when using just water, and a bottle of water wetter, but that is due to the greater heat transfer of a purer mix of water vs water/antifreeze. To suggest that water wetter product itself is "more effective" in a %100 distilled environment is incorrect. The water wetter is still going to increase heat transfer by reducing surface tension in any mixture. Here is the link to some of the tech specs of the product: http://www.redlineoil.com/content/fi...ech%20Info.pdf Note the graph on page 1, right hand side. DYNO TEST RESULTS Dynomometer tests performed by Malcolm Garrett Racing Engines showed significant improvements in coolant temperatures using WaterWetter®. These tests were performed with a Chevrolet 350 V-8 with a cast iron block and aluminum cylinder heads. The thermostat temperature was 160°F. The engine operated at 7200 rpm for three hours and the stabilized cooling system temperature was recorded and tabulated below: Cooling System Fluid Stabilized Temperature 50% Glycol/ 50% Water 228°F 50/50 with WaterWetter® 220°F Water 220°F Water with WaterWetter® 202°F These numbers are similar to the temperatures recorded in track use and heavy-duty street use. |

My 135i is a backup car if it rains hard next weekend at the track and planning for contingency. My track car has tires that won't do in the rain. |
