I don't know. All I know is that my car is staying insanely cool. Even in heavy city traffic. At the heat of the day. And it wasn't doing this before with half the grille blocked off. Then it would kick in the fans all the time. I've never seen it get above 184 (fans on at 186) before I get moving again.
It works.
The next tank might be a bit off since I'm dumping in 2 bottles of Techron. 18 gallon tank means 1.5 bottles according to directions, but 2 are going in for good measure.
