Here’s the uoa from my Champion inverter generator 8750 starting/7000 continuous watts. I broke this generator in for 5 hours with Valvoline daily protection 10w30. I then changed the oil using 1 quart of HPL NO VII and 0.2 quarts of HPL PCMO 5w30. I had to use the generator for 73 continuous hours during a recent power outage. The generator was only shut down to fill the generator with gas twice daily. It ran in eco mode a majority of the time. It had a moderate load on it; less when we weren’t home. This wasn’t ideal as I would have liked to change the oil a second time prior to actually needing it, but that wasn’t feasible. Nonetheless, the oil held up well. I will be switching to 5w40 though.
