Yes, the Tri-Flow is different. I don't know the exact chemical make up of it, but it penetrates better and does lube better than regular sewing machine oil.
I've had several sticky machines that wouldn't cooperate free right up once I started using the Tri-Flow in them.
I don't think it would hurt to try the T-F spray, but the little drip spout bottle is really good for getting the oil right where you want it.
