So I changed my oil and filter a couple days ago. When i refilled it only took about 4 quarts, and the dipstick said it was overfilled. So I drove it for a couple days, no change. Everything I've read says it should hold 5-6 quarts. So it finally bugged me till yesterday i decided to redo the whole change. Same thing. I made sure to drain till it was bone dry. This time it took 3 quarts and is reading full. Truck's running great. What the hell? Should it take that long to circulate? Or am I just being paranoid?!
