I just filled it with oil and put gas in it. Started it and it seems to be working fine. Purchased it for emergency use this winter and for camping because of the size.
Just purchased and performing break-in. Generator produces the advertised output. Easy start. Generator is a little noisier than I expected but not bad. At lower loads it is quieter. Just needed a small portable unit to take to events and tailgates, with an extension cord and putting on the other side of the vehicle the noise is not bad. All in all a good little unit.
