Unless you oiled a lot it's fine, the probem occurs if the oil seeps into the motor. You can likely move over to some kind of grease with out further worry. The Singer grease made for these machines aren't made any more, or rather the same type is, but hard to find in sensible quantities (less than bucket size); Triflow is popular, but there are lots of other suitable greases with teflon too, some sort to vaseline.
