During my amateur aircraft (Experimental USA) days and involvement with servicing Rotax 912, 912s, 914T aircraft engines we had a web site like this site were we had many discussions on coolant types best to use.
Rotax bulletins came out and recommended to use a non water base coolants.
Polypropylene glycol instead of the water diluted ethylene glycol based coolants.
The first being safe to eat and cook your fries in ( a laxative )and the other being very toxic especially to cats that seem to like the sweat taste of it.
Silly cats.... I always recommended Evans coolant to my fellow Rotax pilots. http://www.evanscooling.com/ it has properties that exceed ethylene glycol but does cost $$ more and you must flush the coolant system completely of the old stuff before using the new stuff. You might find the Jay Leno video of it interesting too.
I wanted to revive this thread and see what others think here on Spyderlovers about this coolant for use in our Spyders ... I will change my coolant at the end of the season but want to see others opinions on this product here. And hopefully hear some Sypder pro's chime in on this topic. Thanks.. Frank.... from the land of back bacon and beavers.
