Oil Cooler, How cold is too cold?

Exhaust

If I were to buy a row, at point which should I cut it in half? I'm assuming anything over 240 is high for you?

Cut it in half with a block off plate? That's up to your cars temp gauge.

Anything over 260 is bad. At that temp oil will start to break down really fast and no longer protect. This is where picking the right oil matters. The better the oil stock the longer it will protect and not break down at high heat.

FYI redline and motul use the best stock called polyolester.

FWIW, some experts consider 210-215F to be the optimum oil temperature (best viscosity, shear strength, &c) for a DD. Just what I've read so YMMV.

It depends on the oil. Amsoil usually gets to that point faster when the oil is cooler. Just a thought. I use whatever oil works best for me. I am not an Amsoil bandwagoner.

Yeah. Probably varies a bit between types/brands and what engine they are used in.

My guess is that the boiling point of water has more to do with the experts' figures than shear strength or other parameter (most graphs aren't very steep once the oil gets over 180F or so). I've seen 212F/100C used more than once. BPoW may just be a convenient reference point. Maybe it's to make sure any water gets boiled off. All I know is what I read on the Intertubes.
