This beautiful 2013 Porsche 991 Cabriolet came in for an oil change. The process for this car is a little more involved than earlier versions of the 911. First, the trunk is put into the service position, the fans are removed, the plastic cover is removed, the air filter is removed and then the oil filter can be accessed. After everything is reassembled we use our Autologic diagnostic tool to reset the necessary items in the cars Engine Contol Computer to reflect the oil change. At DART auto only use OEM filters from German suppliers like Mahle and Mann. We have chosen Porsche approved Motul 5W40 as our standard oil for late model Porsche cars. We feel this is one of the best oils you can use in your late model Porsche 911.
