GRA Posted January 30, 2013 Share Posted January 30, 2013 I'm changing the oil in the pump on a pressure washer and the book says use non detergent oil. I was wondering if synthetic oil was non detergent? How about diesel engine oil? Quote Link to comment Share on other sites More sharing options...
Whoaru99 Posted January 30, 2013 Share Posted January 30, 2013 All current spec automotive, diesel, motorcycle, etc. engine oils are detergent-type regardless if conventional or synthetic.Places like Fleet-Farm usually have non-detergent oil. It will say so right on the label. Usually it's in the section by the house brand oils. Quote Link to comment Share on other sites More sharing options...
Tom7227 Posted January 31, 2013 Share Posted January 31, 2013 I bought some at the area where they sell the pressure washers and it was marked as being for them. Try that. Quote Link to comment Share on other sites More sharing options...
theoilman Posted February 13, 2013 Share Posted February 13, 2013 Yes, all of today's engine oils for gasoline and diesel engines are high detergent. To get non-detergent it has to be 'SA' or 'SB' only rated - which can be rare to find anymore.AMSOIL Compressor Fluid/Oil, when you read the full data sheet, is perfectly suited for pressure washers, as well as air compressors. (It is non-detergent.) Quote Link to comment Share on other sites More sharing options...
delcecchi Posted February 13, 2013 Share Posted February 13, 2013 I am pretty sure Fleet Farm sells non detergent oil right next to the detergent stuff. Quote Link to comment Share on other sites More sharing options...
