Ok so I know many on here still stand by the Mazda only coolant. That being said it well know and documented that engine Ice has cured overheating in bikes for a long time.
Ive had great success with it in everything I’ve used it in.
So as many my 8 had a tendency to run on the hot side. So I flushed the system and replaced with it.
Now I’ve never had any issues with any type of deal or o ring with this stuff. I also called and asked. They said it’s perfectly safe for our engines.
So I’m currently on year 3 with it in my engine so I’m gonna say it’s safe and definitely safer than getting it hot during track days. My new rx8 auto is also now running it. I will try and keep everyone up to date every year. This may help many who have issues and may save a bunch of time and money.

 

It's not just 'Mazda Coolant', it's FL22 coolant, which is deemed 'long life'.
Older models as long as 10 years/120,000 miles.

If your reasoning is to keep your engine cooler, fine.
If your reasoning is to save time and money, this ain't it.

Engine Ice says change annually, and for racing applications, twice a year.

There are several brands of FL22 coolant.
If you don't use FL22 coolant you should flush your coolant system annually.

 

I understand that it’s fl-22 but commonly referred to as Mazda coolant which it indeed is not.
And yes I was simply letting people know that it indeed does help with the cooling issues these cars have and so far has not caused any issues over 3 years of use.
It indeed does need to be changed more often to keep its added cooling functions. But it’s not a big deal for me as it is non toxic and biodegradable which is the worst part of normal coolant is the hassle of dealing with it after.
I simply change mine every spring as part of an oil change or spring cleaning if you will along with my trans and diff fluid .
Just wanted to make others aware it may be worth a try and far easier than installing a different radiator. Or worse yet over heating the car on a track day or hot summer cruise.
So you are correct in everything you said this was more as a “hey this seems to work for me and has not caused issues over 3 full years of use”
It indeed cured my issues with temps creeping upward on long session track days.

 

Oh and it indeed is not to save time or money. Lol
I would not own a Mazda if either of those were my main concern. But I love to tinker with my stuff and pretty much waste time with them.
