I don't think the gtx is good oil anymore . Do you know about brad penn oil ? Trust me , you want to do your own oil change . No one will do it as well and if they do a poor job of it you will be unhappy . Many people have had their cars overfilled by shops .

Reading the dipstick on a 964 is clear as mud, make sure the engine is warm, been at idle for a few min. dip wipe and repeat , followed by overfill.
