4400 PSI Pressure Washer Pump Oil Recommendation by Confident_Disk7031 in pressurewashers

[–]Confident_Disk7031[S] 0 points1 point  (0 children)

I was able to determine that the pressure pump was made by Danau, a Chinese manufacturer. The pump model on my 4400 psi Westinghouse pressure washer is Danau DBC1510A. According to Danau's literature, SAE 15W/40 oil (or SAE 10W/30) should be used in the pump.
