(2017 R) Less than ideal oil change at the dealer this weekend. Long story short, after driving the car home, noticed a trail of oil - about 12 miles. After the car sat in the garage for a few minutes, a dinner plate + sized puddle formed. The car holds 6 qts, and after adding the only 2 extra qts I had, it brought it to the bottom of the measuring area of the dipstick, I estimate it arrived home approx 3 qts low. Car sounded normal, no low pressure warning lights, oil temp normal. Had it towed back to the dealer and apparently a bad O ring around the filer is to blame. I would imagine these engines can tolerate a low oil situation, but was wondering if anyone could share their similar stories with me and the outcome. Car still resides at the dealer awaiting a thorough cleaning and check it ensure all is well. Any suggestions on what I might consider requesting the dealer to check would also be helpful.
