I'm using Royal Purple in everything I own from chainsaws to the H3, good schtuff. Dyno numbers don't lie.
I started using RP products years ago in our power plant equipment that runs 24/7. Extended run times, longer equipment repair intervals (or complete lack thereof), cooler operating temperatures, and actual lower vibration readings and quieter equipment have all been experienced by changing to Royal Purple lubricants.
Just loaded up our new milling machine with it after the startup run.
Best of all, I just call this guy up,

and get it to the door, FAST.
Mobil 1 filters, Royal Purple oil, equipment very very happy.
If you have an application question, call Royal Purple directly and their lube engineers will help you immediately.
