I had changed my oil on my X3 bmw 2013 28i. I put in about 5.7 Qts and drove until warm. After checking iDrive Oil reading it showed as right below "Max". I then research on this forum and found out it takes close to 7 qts. So i added another quart which made it around 6.7~ or less not more. The following day, I check idrive and it showed it as half and today It show as minimum. No warning low oil unless i do a system "measuring" test. Please help! I m in San Diego, NO temperature change or anything
