Miriam, NO I have not had this conversation with you before. I also said it was JMOHO, that you should use the product that is made for what ever you are working on. Like in this case, sewing machine oil for a sewing machine. I have NEVER used Tri Flo, because of what I had read. That was a while back. If you like it and want to spend the extra money, then go for it. But again JMOHO, I will stick with good old sewing machine oil, as it has never failed me yet.
I was trying to find where I read this, and found this interesting, this is a forum where guy's fly (toy,for lack of better description) planes, and helicopters, and one guy posted this....a few guys where i fly use oil made for home sewing machines..a lot of oil for a small price, and you can pick up a bottle at WalMart Again it is what you want to spend your money on.
