I would say it's down to you.
I changed the oil filter, filled with cheap 10w40, ran it for about a mile, drained it, dropped the sump, cleaned it & the intake filter in the sump, I was fortunate as I found the sump to be pretty clean, a bit of mayonnaise where the breather pipe enters the sump at the rear.
Put it back together with new filter & 10w60 synth oil.
I'll just change as normal from now on.
