Been using Ken's Ultra-Pure valve oil and slide greases now for a week. I'LL NEVER USE ANYTHING ELSE, EVER AGAIN! I've used several different oils on my 76 Bach over the years and have never been able to get rid of the sticky 3rd valve, that is until I got my Ultra-Pure kit from Ken's EBay shop. For $13 (that includes shipping!) I got rid of the sticky valve and the greases are the slickest I've ever used on the slides! Get some of Ken's valve oil and slide greases, you won't be disappointed!
