A generator that had spent five years in a garage was the focus of an online discussion about whether bringing it back to life, keeping it, or selling it made the most sense.
Much of the conversation came down to a basic question: Had fuel been left sitting in it?
“My girlfriend has had this in her garage for five years. Worth getting running, and any info on it? If she sells it on Marketplace, what’s a fair price?” the original poster wrote in Reddit’s Generator community.
Price estimates varied sharply, depending on whether the generator worked. In uncertain, non-running condition, some commenters said it might bring a few hundred dollars, while a cleaned-up unit that functions properly could land $500 to $1,000, depending on its condition and fuel options.
“Five years sitting in a garage doesn’t necessarily mean it’s done, but I’d check the oil, fuel system, battery, wiring, and rust before trying to run it,” one user wrote.
Another user said: “Wincos are good, quality generators and this one appears to be set up for tri-fuel operation. It’s possible it will start as is if there was never any gasoline in it. If there was, the old gas has probably gummed up the carb, tank, and lines.”

Commenters said old generators face a tough resale market because cheap, new models have pushed down what buyers are willing to pay. Several noted that brand recognition alone is not enough and that buyers want proof the unit starts, runs, and produces power.
The thread’s pricing advice repeatedly returned to the same conclusion: that safely getting the generator running was the clearest way to improve its value.
Whether someone is browsing garage sales, scrolling through online listings, or shopping at thrift stores, buying used can save money on everyday purchases and uncover rare or premium items at steep discounts.
There is also the added benefit of reducing waste. Extending the life of a durable product keeps it out of a landfill and reduces demand for a brand-new replacement, especially when the older item is repairable and made with dependable parts.
These stories look at the same kind of choice: whether an old backup unit should be kept, fixed, or replaced. 
• Homeowners weighing backup power questioned noise reduction options that could affect airflow and warranty coverage.
• Many homeowners opt for next-gen options such as backup batteries paired with solar.
• Energy experts say to upgrade a backup generator when a newer system offers benefits fuel-powered units never can.
Getting an old generator running is only one piece of a decision. It also matters how it performs day to day, how much upkeep it needs, and whether those trade-offs are worth it when compared with other, less polluting options.
