cooler longer before going back to the oil pan? What good would an oil cooler be if the oil just flowed in and out as quickly as it came in?... They also sell an oil thermostat/restrictor that is there to block off the oil from going to the oil cooler when the engine is cold but that is only recommended if you're one of those people that can't help but to floor it when the engine is still not warmed up.
