A shopper who thought they were opening a brand-new 4,000-watt inverter generator instead found a gas smell, oil already in the unit, and a box that appeared to have been taped twice.
That raised a costly question: Was the machine simply factory-tested, or had someone returned it and resold it at full price?
Here's what to know
The buyer said they bought the generator in June, a couple of months after the product's April release, and left it unopened until they finally needed it. In a post on the subreddit r/Generator, they wrote, "When i opened it there was a gas smell, and today i checked the oil and theres oil in the unit."
They also noted, "The blue tag in my first pic alerts the user to NO OIL IN UNIT." They said the box appeared to have been taped over more than once.
People in the comments said a small amount of leftover oil can sometimes be normal after quality-control testing. One commenter explained, "They will have residue from being tested. If it is full and has no bottle of oil to add, probably used." Another added that their own new unit "had a bit of oil left over from the factory test — enough to drip out similar to what is shown in your photo."
More background
This kind of situation can happen easily with emergency equipment. Many people buy a generator well before storm season or a blackout, then leave it boxed up until they actually need it.

That delay can postpone the moment when missing parts, prior use, or repackaging become obvious.
Some commenters said the situation was not entirely straightforward. One person called factory test-starting "Normal," adding, "They test start them for QC — then drain most of the oil." A small amount of residue alone may not necessarily mean a buyer received a used machine.
Catching a problem early can help protect the value of a purchase and reduce the chance of discovering an issue only when backup power is suddenly necessary.
What can be done?
Commenters recommended checking a generator soon after bringing it home instead of waiting months. In this case, they suggested looking for the expected oil bottle in the box, seeing whether the machine had an hour meter, and checking the muffler for signs of prior use.
They also cautioned against assuming that any visible oil means the unit is ready to run. One commenter said, "Don't run it until you get that oil level down to normal," while another explained that the generator should be checked on level ground and that oil should sit at the bottom of the dipstick threads.
Before the first startup, the manual resolved the buyer's core question.
"Hi problem solved the manual itself literally states it has no oil from the factory. Should have read it carefully … so yes it's been used," the original poster said in the comments.
A quick inspection like that can make a possible return easier to identify and address than if it sits unopened for months and is only needed when the power goes out.
