Coolant heats up quicker than oil, so the oil/coolant heat exchanger works to heat the oil quicker during warmup, then keeps oil temps stable once warmed up.

I was thinking of adapting an oil/coolant heat exchanger onto my car. Later versions came with one, so it's a bolt on affair. It's attached to the oil filter housing with two nipples for coolant, so routing the coolant lines is easy. I'll check and see if it's adaptable to other cars with similar size oil filters.
