I've been running the Snow Performance system in my vehicle since Aug 2018 and have used it probably less than 10 times on a 50/50 blend to date because of his claim.

I've not heard anything like that, but I have heard about issues from too much of an E-blend for gas, because it can remove the oil coating from cylinder walls and valve train etc.

It's unclear what you mean by 'heads have blown'... Do you mean the head gasket? That is possible, but more likely due to running too much boost.

I run 50:50 WMI on my car every single day. I have the Aquamist progressive system so it comes on progressively based on a combination of boost and injector duty cycle (mostly duty cycle). I use it to increase octane, and for cooling.

It seems strange to me that you've used it less than 10 times. You're either tuned for it or you're not. It doesn't increase power output on its own, unless the map you're running is actually for a higher octane and you letting the DME turn down timing etc., which isn't a good idea anyway.

I'd say that it may actually be good for the engine, but you should have it on all of the time, and tune for that.
