Is there a particular oil, or viscosity of oil that is recommended for front action valves? Should a heavier oil be used, as the valve is on its side?

Does anyone (everyone) have recommendations for a brand of oil? I use Hetman piston lubricant 2 in my other instruments.

In my case it is for a Conn Connstellation.

I assume no special care is needed, just oiling and cleaning the valves when I play.
