I recently had pressure washer stolen and now finally after some faff it has been delivered. I need oil for the pump but neither the bunk of info that came with it nor manual says what oil to recommend. Im thinking sae 30 non detergent but this seems very hard to get hold of locally to me anyway. Is my thinking right or should i use different oil?
Thanks in advance for any advice

Best you phone the supplier first you got the washer from to confirm what oil should be used for the pump and motor as could affect the warrantee.

If it's an interpump then this will do https://www.rutlandpumps.co.uk/products/interpump-high-pressure-plunger-pump-oil
