Ultra-Pure Oils UPO-VALVE Professional Valve Oil

No puedo decir mucho del aceite, solo que es muy bueno. Solo como recomendación, no mezclen aceite sintético con otros, si van a usar aceite sintético, laven los pistones y el instrumento y ya luego agregan el aceite nuevo, ya que cuando se mezclan, no se notan los beneficios del aceite sintético.Amazon como siempre excelente.

Works great with my Yamaha 8310Z. Like any valve oil, how well it works depends on the physical characteristics of your valves and casings. For my horn, and all of the other Yamaha trumpets and flugelhorns I've used it on, this oil gives the valves fast action that lasts days longer than the other products I've used before. It's odorless and leaves minimal residue. I use the Ultra Pure slide greases as well, and the slides work great with a drop of this oil added to the grease.If you're not satisfied with your current oil, this stuff is worth a shot. Be sure to clean your horn before adding it in case it doesn't mix well with other oils.

Beautiful synthetic oil that after doing lots of research, was the clear choice. Be sure to pair it with Ultra pure slide grease so they wont counteract each other. Worked like a charm on 2 of my sticky valves. Be sure to clean the valves and casings thoroughly first, with lint free cloth. Now I will get the refill size for a few dollars more and keep it stock to refill this little bottle.

Valves are faster with this oil than any other I've used. Lasts long and minimal smell.

I purchased this for my son, who is a student musician. It is a different brand than he is used to using but he is happy with the performance and we will keep this in mind for future purchases.
