Cat pressure washer pump oil vs SAE 30 non detergent

[hondaDIY]

Hi I'm looking for a pump oil for my briggs pressure washer (it's just a cheapy horizontal spark one). I see this fancy cat brand oil, and then I see a lot of other brands that just sound like non detergent sae 30. What's the move here. Should I just buy some sae 30 non detergent? Or this 'pump oil' sae 30 stuff different, or is the cat stuff god's gift?

ND 30 is acceptable for a Cat pump.

I kind of doubt it's a cat pump. it's what I assume is some random cheapo one. Pressure washer looks like this. I think it's innovi pump
