I changed the coolant last weekend.
The stuff that was in there was a very dark, dull green and seemd to be real viscous or thick.

So... What does Evans coolant look like? Is it a dark green rather than the "flourescent" green of the standard Prestone coolants?

I understand it has no water mixed with it. Is it "thicker" and more viscous than the standard coolants?

If it was not Evans waterless coolant, then I am glad I changed it.  I have never seen coolant look that dark green and wonder, if it was standard coolant, if the PO ever added water to it.

The 50/50 premix I got from the Stealer (didn't know any better at the time) is Dark Green.  Grass green, doesn't seem any thicker than regular coolant though.

I found references on the Internet. I guess teh Japanese manufacturers (i.e., Honda) prefer POAT type coolants and this may be what it is.

Phosphated Organic Acid Technology

I just used the Prestone Pre-Diluted 50/50 Extended Life stuff.

I have found references that some coolants that are prediluted come in 55/45 ratio... That would explain why it may have seemd a tad more viscous I guess.

The Evans NPG+ I put in had a purple tint to it.

Do you still have that fluid in or what is the time interval to change fluid?

Here's the stuff I use in both my car and bike.

Top rated!!

It is imperative to keep aluminum motors running in good condition.(Proper coolant condition)

There are tons of articles regarding deterioration of aluminum motors due to poorly maintained cooling systems and most every one deals with the coolant itself!

Whichever you may choose or whatever way you may decide to go, taking care of the coolant and the cooling system is vitally important.

Do a Ph check on your coolant. It's easy and will reveal any possible problems with the coolant.

This is where it starts.
