I have used the same indie oil change shop for many years with all our cars. I usually have the oil drained with a warm engine. They use a few blast of compressed air at the end (is that a good thing?). In my case 8 qt always overfills and I have them stop at 7 1/2, then drive the car up to temp. and add as needed. There are several write ups under oil change and lubricants on this forum (search box). It may be time for me to re visit as well. Thanks for reminding me. Horst K
