I usually try to stay out of these threads as they typically devolve into personal attacks... However this forum typically is above that sort of thing, and I believe this coolant is a good option for the kind of duty our rigs see.
Bottom line is u should educate yourself and make a decision based on that, not what anyone here says.
Here is an article from High Performance Pontiac on Evans coolant:
http://www.hotrod.com/articles/waterless-engine-coolant-and-cooling-system-basics/
Reason I added it here, is the Pontiac motors are the same era for the most part as our Olds motors and similar in a lot of ways.
Earlier, someone mentioned the difficulty removing water from the system to convert. Evans makes a "Prep" fluid, but it is pricey. However, before the came out with the prep fluid, they recommended you drain your system, blow out the old coolant with a high volume air source such as the blow output of a shopvac, then fill with Straight Sierra coolant. (Pet friendly coolant that is also propolyne glycol based) Drain and refill like this until moisture level of the Sierra goes below 2%, then fill with Evans. I've found it takes at most 2 drain and refills of the Sierra.
Someone also asked about freezepoint. Freeze point or Evans is very low. Website says it turns to slush at like -50, but never really freezes solid.

At 40+$/gal I am not sure that I care. I will try to get an MSDS from them. (Lord knows I have enough others, but my company @ddress has died.)
The specs read a lot like straight Propylene Glycol, but to charge that much there better be more.

If you count the flush you are supposed to use to "clean" the engine $77 a gallon. I would cure the problems not treat the symptoms. Then you don't need this stuff.

Mark,
Your points are well supported, and I have known many that ran straight E-glycol in engines without issue.
And in your case in Texas, (One of the reasons I ask for a location in sigfiles) it will probably be successful. The big three up here all tried it. I know, because as the aftermarket guy for McCord Gasket, I was suddenly tossed a smoking hand-grenade that was this issue. We have no idea what our material compatibility was with straight glycols both E and P.
After an initial panic, I found we had a very low risk. When GM came to ask because they were thinking of recommending this for the Corvette, I was able to supply the GM account engineer with my data. He was much relieved.
In my searches, I did run into the Rotax issue, and further digging did confirm that the engines were expected to run at higher head temperatures with this coolant. What one also has to remember about aircraft engines is that they are relatively low specific horsepower.
We could not test this in our own labs at McCord because they were specialized for thermal cycle testing and used an open system. I had to some fast footwork to get data that we needed. It was an "adventure" to be remembered.
I still do not have the technical data about Evans that I would like. They do not ever mention a water pump seal lubricant and that sort of worries me. While no glycol will be an electrolyte and hence not be party to any internal corrosion, without this function, I might have some concern.
In Michigan (where fender solvent is applied to the roads on a regular basis), one is as likely to loose a radiator or condenser to external corrosion. (Right Nick?) In that case, loosing a $200+ coolant fill is less attractive.
I am going to stick with a known issue with the engine work I am doing this winter.

I've used many, many ground straps trying to stop electrolysis from eating an alum radiator up. But, Water is the path of least resistance and it always eats the alum. Cadillac had extreme problems with the North Star engine. So much so, most had a display of a alum block eaten nearly paper thin. Distilled water may not have minerals in it but don't stand in it and grab 220 volts No matter water still makes the best coolant if properly mixed with antifreeze and changed once a year ...Tom
