@sandman7849 yes sir. The oil is pretty easy to change on it. Also it's good to add some fuel injector fluid with the gas as well to help keep the carburetor/ injectors clean.
@rothenbj, yes I ran it for 18 hours and filled up while running. I know thats not recommended, but that's what I did. I'm not sure if our 5 ton AC unit was during that time. But this Generator is a BEAST for the price and durability.
Yea this generator is a beast. I was happy to finally use it, for the house. I use it daily for my Mobile Detailing Business. But I'm very pleased with this Generator.
