Generac pressure washer, Honda GX160 5.5 HP.
Out, not sure, likely Delo straight 30 weight.
In, VR-1 synthetic 20w50. Yep, it's thick, but at one point in the GX line, Honda had 20w50 in the temp chart. Overseas kart racers regularly use 15w50 as their "official" oil for the GX160. I'm not concerned, I don't think you can kill a Honda small engine with any oil choice.
Also replaced the carburetor with an Everest kit. The whole carb was about 16.00 on Amazon, and included the tank screen/fitting, fuel line, and gaskets. Nifty kit, about 30 minutes of work, fired up quickly and settled into an even idle. The old carb had something wrong, for the price, not worth troubleshooting. Engine would not start without ether, took forever, surged, and if ran out of fuel, the whole process was repeated.
