Hi Guys wondering if anyone knows the working temperatures in Fahrenheit? Also. I am using royal purple compressor oil. 5 hours between changes?

Yong heng temps and oil changes

Between 120 and 150 fahrenheit if you use a clear oil you can see when it looks dirty (#30/ ISO100 non detergent) motor oil works fine.

I run two, bought a year apart, and my older one runs at 125f and my newer one runs at 150. I use Royal Purple too. I have changed the cylinder head on the old unit too and they still operate at different temps and each has its own personality. I don't worry about them breaking either, I fill my cylinders to 4500. If they break, I fix it. Happened once, to an old style head. It wasn't a catastrophe either, the unit just wasn't getting above 3500 psi. My only complaint with Yong Heng's, at their price point, is how noisy they are.
