Oil cooler question

[Vegas69]

There is always a compromise huh Carl. I've found my car runs way to cool in the winter as well. Mine went down to 125-130 on the way to the Optima challenge and it wasn't that chilly. I'm ditching the high flo t stat for a stock GM 180. I've read teh high flo stats don't like to close after they open until they cool off. My fans don't come on until 185 which would be reasonable for you. You're running alot thinner oil than I am so it probably not as big a deal. I just don't like not burning off the condensation in the oil.
