Difference between 15w40 and 10w40 in a pressure washer

[ipwn]

My electric pressure washer says to put 15w40 in, seeing as I have a surplus amount of 10w40 in the garage, will it make much of a difference if I pop that in instead of 15 ?

Thanks

It'll be too thin, as at low temps such as in the pressure washer the first figure matters. So 15W50 or 15W30 would be OK, but not 10W40.

Ah damn, thought I may be able to get away with it !

It's been a long day, but why would you need to put anything other than electricity and water into an electric pressure washer?

Thank God there's always someone else willing to make themselves look like a complete arse by asking a question I've been itching (not my arse) to ask

I don't know the relevance, it was built in 1986 and still runs like a charm

I don't see why you couldn't. It's not likely to be fussy about what oil it uses, I suspect it's going to be happy with any sort of oil of about the right grade.
