Pressure Washer Oil

[Toddd]

I have a Power Systems Super Porta Pro pressure washer that I got a couple of years back. I decided to get out and see how it's working. Of course, something had to go wrong. I am not seeming to get very much pressure. There is an oil cap for it, though. Does anybody know what kind of oil these things take?

Well, do you mean engine oil or pump oil? The engine takes standard motor oil. The pump takes pump oil, or 30wt non-detergent oil if pump oil is unavailable. Me, I use 90wt gear oil, as all the seals are shot and it keeps the oil in longer...
