The Honda power washer can use any SAE certified two cycle engine motor oil. The motor oil usually is available in one ounce bottles.
Edmuns.com has an article on it which says that ExxonMobil is a blender of Honda motor oil.

The motor is a Honda G300.
If its a manual transmission any 5w-30 motor oil will work fine. However I personally use Honda's specific manual transmission fluid, available at any Honda dealership.
