Yesterday we went for a short ride [little over a 100 miles] when we got back I checked the oil and no oil on the dipstick. Let it idle till the fans came on, shut off and checked oil after about a minute--nothing. Checked it half a dozen times in the nest couple minutes--still nothing. Looked over the motor for any oil residue, no leaks. Looked at the tail pipe for signs of oil burning, just slightly black. Looked at the two tubes under the back of the motor, no oil residue there. Thought I would see just how much oil was in the motor so drained it and got 5 quarts out, so it was full but nothing on the dipstick. Just wondering if anybody has any ideas as to what is sucking the oil out of the cavity where the dipstick is or the oil is not getting to the dipstick. This is a 2016 F3 limited with 12,000 miles. Dealer did the first service and I did it 2000 miles ago. Any ideas?
