I would think an oil cooler would allow the engine oil to be cooler all of the time. From the OP's description, the car got just as hot but cooled down faster.

No offense to the OP, I don't think the review is in anyway conclusive. Now, there is a cooling benefit as the OP described when the car cooled down.
Before anyone makes a judgement on this mod, we need actual oil temps since that gauge is probably buffered.

Maybe the oil temps were high because of the OEM thermostat or some other engine management parameter?
