I use/used Hetman oil on both of my Yamaha euph's and also recommend it. I was also frustrated before switching.

Two additional things to check. When you clean the valve casings, clean out the valve guide slot with a soft tooth brush and look for funny wear on the guides.

Then, with the springs out, gently push the valves back and forth in the casings to see if there's a "catch" any where. If so, and you can't diagnose it, your repare man might be able to.

Best of luck
