Pressure washer pump oil?

Doing some surgery on my pressure washer [seal kit] and had to open up the pump further than expected to pop seals out. It's a Craftsman with a 3.5 B&S.

Question: Is the replacement oil critical enough to hunt down the genuine B&S stuff (190586GS) or is there an alternate? I surfed around and found a number of opinions, mostly mentioning 75w90 syn gear oil. Of course I value the answers here the most.

Hello the_tow_guy,

The mentioned gear oil will work just fine for this application.....

Howdy tow guy,
That's what I'd use too.

Thanks, guys; my instinct was that I didn't think it would be critical, especially since what came out was a grayish ooze from water intrusion and even that apparently had sufficient lubrication properties to suffice.
