I installed a gasoline engine in my Rivian

[JeremyP]

I put exactly 1 gallon of gas in the generator and let it run until it stopped. It had previously run until it stopped so it should be a true 1 gallon test. It fell into the lowest efficiency range that I’ve seen for an inverter generator, and clearly the rated numbers from the manufacturer are overly optimistic. While this generator is five years old, it got a brand new carburetor and full tune up about nine months ago.

Anyway, based on that, 13mpg is the true final number. When I ran it in camp, I had a gut feeling that it was consuming gas far faster than I had expected.

I guess I wasn't too far off
