I am using the OEM oil filter (the black JDM one).

Lately, since I added an oil cooler, I have been particularly obsessive about my oil levels and oil pressure (I don't have much to go on since I don't have a gauge :/, just the OEM light).

I unscrewed the oil filter to readjust the cooler lines. Upon reinstalling and cold starting the car, I noticed that the oil pressure light lingered for maybe a couple of seconds before going away. I am guessing it was because it had to fill the filter? The next start (albeit not a cold start) did not do this.

Any damage done to the engine? I assume this is within the range of normal treatment to the engine because not everyone is going to pre-fill their new filter when changing oil.

Of course, having an oil filter means there is more oil and resistance for the oil pump to push around, so I am trying to make sure that my "preventative reliability"mod is not going to hurt my engine in the long run....
