JENNR8R, Mariah,
Both your mechanics are wrong. If you don't sew but once a year then you might get away with a two year service schedule, otherwise you're damaging your machine. Sounds to me like these two guys are trying to cause your machines an early demise so they can sell you a new one.
There IS NO SHORTCUTS to oiling a sewing machine. The bobbin race area is a miniscule part of the machine's lubrication requirements. Oiling that would be like squirting oil on the throttle linkage of your car and ignoring the rest. It won't do.
Instructions for oiling a FW or most any other machine are found in the owners manual. They can be downloaded from the Singer site FREE. I'd suggest doing that and printing them out so you can have them with the machine.
