I changed my oil recently. Easy job, but I think next time I will run the car up the driver ramp only so that ALL the oil drains out. I put in 8.2 QTS of oil in after filter, but dipstick showed overfilledt after dropping car down. I drained out 3/4 of a QT, but it still shows high. The electronic display showed over, but now it does'nt. But it still is high.
