Review on Derale 15604 Engine Oil Cooler by Jonathan Davenport

Reduced engine oil temperature by 10 degrees at 70 mph. Not very radical. I still got 270 on the highway with my VQ35HR engine. And it was a great day relaxing. I will install a bigger cooler. It wasn't enough. The oil temperature drops fairly quickly during the cool down lap. But as for holding on while running, no. Not enough. Definitely far from 50 degrees as advertised. At the same time, the quality is top notch. This is a very good device and the overall drop of 10 degrees is decent for such a small device. I was just hoping for more.
