Why won't anyone change the oil in the 944?

This is getting ridiculous. 8 places that "specialize" in oil changes refuse to do it. WHY?! The place today tried to tell me that the engine needs to be turned over in a special way when the oil is changed. ugh...One a few weeks ago said they didn't have the tools need to change the oil in it. I refuse to go to a Porsche dealer and pay $120 bucks for an oil change!!! I'll probably break down and buy the shorter jack stands so I can do it myself at home.
