I just had my oil changed with 7 qts Mobil 1 0W-40. When I got home, I double checked the oil level and it appeared to be considerably beyond the safe indicator on the dipstick. I took the car back to the service center and we measured it several times. On the side of the dipstick with the imprinting for measuring levels, it appeared to be about 1/2 quart high. On the backside of the dipstick, it was in the safe range. How do I interpret this? The service center said that they have seen this prior on other SRT models and were instructed to read both sides of the dipstick and refernce the lower of the readings. I checked it again this morning and saw similar results. The oil level on the side of the dipstick was above the safe line, but again on the back it was at the top of the safe line. I am concerned and understand that too much oil is worse than too little. Please give me some advice here.
