pressure washer air compressor oil

[bedwards]

Is there any difference in a non detergent 30w air compressor oil and pressure washer oil? I have a gallon of Pure Guard air compressor oil and wonder if it can be used in my Generac Pressure commercial 3100 washer pump? Its a model #59930 the pump is a Annovi rsv3g31.

thanks in advance

Perhaps the pressure washer oil would have an anti rust/water additive much like a marine engine oil?

That said both can likely take SAE 30 ND so you should be good either way.

I can't comment about the air compressor oil, I use compressor oil for my air compressor. My power washer is over 30 years old and I always used 30 grade non-detergent oil in the pump. The oil has served me well.
