Always best to change oil at minimum as frequently as manufacturer states if not sooner.

I am surprised that the pump uses 14w40. I would have thought it needs an EP oil (Extreme Pressure) I would check with who you bough the PW from. Alternative have a look for manufacturers web site and see what they recommend.

I do my pressure washer crankcase oil every two months and check pump and gearbox oils daily

hi m8 this a small add on to my window cleaning 

just wanted to check on what's the  best oil  as at jetmac told me 15w 40 for every thing but not sure that's  correct for ar pump
