Perfect as designed (not for overheating in normal cond)
This is great at doing what's its designed to do, increase lubricancy of coolant which helps prolong waterpump life and flow through the entire system. Ive used this in my race bikes and cars for years. Doing 1 track day in my car with 25/75 mix and the next track day with 25/75 mix and hyper lube, data logger showed a consistent 2-3° cooler in similar hot conditions. I don't know how long it remains effective because I usually change coolant in my vehicles every year. This is NOT designed to fix ANY cooling system problems or lower temps in normal driving conditions.
