I was driving my jeep down the street when all of the sudden the oil pressure just dropped and the check gauges light came on. I pulled over and checked the dipstick and it said it was almost completely empty. i had someone drop some oil off where i pulled over, and refilled it with about 3 qts, let it settle and turned the car back on. on the way back home the meter kept fluctuating between too high and just perfect, so i parked and let it sit for a day. checked it today and it was WAY too high. is it safe to even drive with too much oil? is it possible to drain some of the oil by myself instead of having to pay for another oil change (i just had one done about a month ago)? anyone know whats wrong with my car?
