My pressure washer is due a service but the info I have is conflicting. I bought it from Q.Washers its a Honda GX390 and in the Q.Washers hand book it says Engine oil SAE 20-50 Gear box oil SAE 90 Gear oil.

In the Honda hand book it says Engine oil SAE 10W-30.

Is there much difference between these oils ? also someone give me some gear box oil its EP75w90 , that is the right stuff ?

 Cheers Justin

10-30 or 20 -50 will be ok. Oil only really matters in extreme heat ranges. 80w 90 sae gearbox oil. Straight 30 non-detergent for the pump
