For your own reference regular 3 n 1 oil contains paraffin, detergents etc. It's not for electric motors, and sewing machines etc. Sewing machine oil is non-detergent SAE 15 also known as Turbine Oil.
Thanks Pat. We really like our Pfaff. It's strong enough to do what it's "not" supposed to do as well as delicate work. It also does 80+ patterns. (Never used them...) My wife sews printer paper together with it.... about 10 pages at a time!
