i was wondering if anyone is using this and had any comments on it. i was thinking about adding some to the max this year but didnt know if it was overkill.

thanks in advance

 

I have used it for entire last year , I've had no prior problems with overheating. I didn't notice any drastic changes in coolant temp. Now i'm running red Toyota coolant and no water wetter.

on the other hand - i used it in my brother's Olds Aurora and i didn't help much at all ( car has constant overheating problems - its factory flawed)

if you live in warm climate try to run it with just water and take coolant temp readings to see if it lowers the coolant temp of about~20 deg as they claim.

I'm using it with the Nissan coolant - no difference on my temp gauge.
