DIYbanter - pressure washer pump oil

I've never heard of a multi viscosity non-detergent oil. Has anyone
else?

Froogle search turned up zero hits.

I'd use 30 weight ND, unless you pressure wash in extremely low or
high temperatures.

My washer needed some spring PM so I opened the pump
(never done this before) and spilled the oil all over the bench.
Karcher specs 15W-40 non detergent and wants almost $30
for a quart. Is there something special about the oil for a
pressure washer pump or can I just use regular 15W-40 ND?
