Why would someone who claims they restore cars use 3 in 1 oil to oil a sewing machine? The guy that I purchased this machine from told me he was into fixing up vintage cars, but didn't know much on vintage sewing machines. Eeks, just to clean the underneath side of this machine I have had to use Goop to cut through the 3in1 junk.
Folks, Please only use sewing oil to oil a sewing machine.
