The stock OEM oil cooler sits very low on front of the car, so it's very vunerable to rocks and debris kicked up from the road.  Be sure to check for damage to the oil cooler that could cause oil leaks.  Be warned that a brand new unit from Mazda is very costly; used units are a lot more reasonable and easy to find.

Check the core for fin damage; minor fin damage can be easily be bent back.  Major damage can reduce the efficiency of the oil cooler by reducing airflow through the core.  Inspect the oil cooler fins very carefully!

The fittings on the oil cooler can leak, but it's most likely the oil cooler lines are leaking.  Inspect the oil cooler lines prior to blaming the oil cooler (fittings) for leakage.
