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.
