So I'm planning on flushing and filling the coolant on my f4 soon. I will be using premix Honda Pro HP coolant. I want to put an additive in to lower temps as much as I can.. I have had.luck with water wetter in the past with cars. With is better? Engine ice or water wetter? Are they both compatible with the Honda coolant? I don't ride in the snow but It does get cold in the winter.. I have ridden in mid to high 30s before.. So I do need antifreeze capabilities.

Any info appreciated.

 

Stick with honda coolant. It will work fine. But if you want to go the other way, engine ice works good on the street.

 

thanks.. I'm going to stick with the Honda coolant.. Is it okay to mix engine ice with it? How much will I need (ratiowise). Is engine ice better than Water wetter? I've never used EI before.. that's all...

thanks

 

engine ice is supposed to be run all by itself. water wetter is supposed to have a little coolant mixed with it and water.

 

I'm a huge believer in both ProHonda 50/50 coolant & WaterWetter.

I've run WW & distilled water mix at Willow in 100+ temps (track temp much higher than that) all day long w/ nice stable engine temp.

You can mix WW & 50% or less ProHonda for optimum street protection w/ varying temps & cooling ability.

Redline (WW producer) has good info on their website... Red Line Synthetic Oil
