Thank you all. I thought I'd missed the memo, maybe! I ordered some grease from Sew-Classics and it should be here in a day or so. In the meantime, I'm just treadling away on my non-greasepot machines! I have also filed a complaint with Singer. It's scary to think that the owner of a Singer shop that's been in business for 40 years is dispensing such advice. Worse yet, he actually said he was putting that oil in the machines when he serviced them. I sure hope they investigate it! By the way, don't get your vintage Singer serviced in Savannah!!!!
