AFAIK, technology is the same for all brands. Prestone's label states " safe for all cars and all metals including aluminum". I'm willing to learn if someone can tell me the very special ingredient that Honda has the the majority don't. Until I know better, use any major brand safe for alluminum in a 50/50 pre- mix.

 

yeah, well actually, i have alot of old milk i might use

 

i'll probably go with prestone, i just remember a few threads a while back where everyone was making a big deal out of it.

i just know its supposed to not have silicates.

thanks guys
