Yeah, some of them are orange, too. Like that dexcool junk.

I wouldn't recommend mixing any coolant unless you're 100% sure what it is, and it's made for use in aluminum engines. Regular green Peak or Prestone mixed 50/50 with DISTILLED water is what I use in everything.

Yep, I've also seen yellow and pink. lol...
Seems stupid as hell to me. It's antifreeze for gawds sake. Do we need every color of the rainbow?
Hmmm... I wonder what would happen if you mixed all the colors together?

 

Sorry Deano I didn't mean to give the impression I was saying you should mix it

As I also said, 'it takes ten minutes to drain the coolant on this bike', a good flush doesn't take much longer and of corse it needs to be compatible with aluminium, but I think most are these days?

When it comes to topping up, I'd use distilled water(unless you know what's in there already) and then investigate why it needs to be topped up in the first place as it may indicate a more serious problem, like leaks or weak hoses and constant topping up will weaken the mixture.

 

AMSOIL makes a biodegradable antifreeze that they say can be mixed. The sealant is the only turn off to me. Not needed so why introduce it to the system.

It almost sounds like it would make a good mixer in a pinch.
