And $50 a gallon is no problem for Jay Leno. If you are really interested read through these posts from guys that own older pre and post war cars. They have some weird cooling systems but it isn't the answer all for all older cars. There is interesting facts and opinions through out the thread. It is interesting that Evans says that the cooling system will operate at a higher temperature but they really can't tell how much. I don't need my engine to run any hotter than it does and mainly because of the hot soak I have when it comes to a restart. The Evans coolant boils (or doesn't boil) until it reaches high temps and because of the lack of water, it doesn't corrode metal parts especially aluminum and the corrosion caused by dissimilar metals. That's a good thing but that's why anti corrosive chemicals are added to ethylene glycol based coolants. The Evans coolant is touted as a "Lifetime" coolant but a lifetime hasn't been tested yet and when it first was introduced it was recommended that it was replaced every 5 years. Any chemical will get contaminated especially inside a engine with heat cycles and combustion gasses entering the system. Although this coolant sounds like a superior coolant, I will stick with my Ethylene based coolant and add a small bottle of anti rust and water pump lube every year. I still have the original coolant in my 02 PT Cruiser. It still tests to -34° and is clean as a whistle. The next time I get to the storage garage I will test the system for voltage (electrolysis) and report back here. Guys, I respect you and your opinions. I just have a different view of this subject. I will continue with my green coolant and yearly additive. It has worked for me for years and I hope it works for years more. What the heck, I might have to replace a aluminum water pump sometime before I become 90 and turn into worm food! http://forums.aaca.org/f169/waterless-coolant-experience-309949.html
