so i was looking through my oil change reciepts and on the last 2 in small letters on the bottom of the reciept it mentioned that there was an oil leak discovered. they never told me about it when i was there and my car does not burn oil or run low on oil. the oil pan is oily but it never has dripped oil on the ground. should i worry about this? im adding some oil leak additives to my oil just to be sure. im going to start changing my own oil now anyways, those bastards over filled it last time.
