What Is Generator Winterization?

Generator winterization prepares your unit for an extended period of non-use. Even in Palm City where it doesn't freeze, generators that sit idle for months without proper preparation develop problems. Stale fuel gums up the carburetor, old oil turns acidic and corrodes internal surfaces, and moisture accumulates in places it shouldn't be. Winterization prevents all of that.

The process covers fuel stabilization to prevent gasoline from degrading, an oil change to remove contaminants before storage, running treated fuel through the entire fuel system, inspecting and protecting battery connections, and ensuring the generator is clean and properly covered. Some owners also choose to fog the cylinders with storage oil for extra protection.

Even though Florida doesn't have harsh winters, many Palm City RV owners store their rigs from late spring through early fall when it's too hot to camp comfortably, or they're snowbirds heading north for summer. Either way, that's months of downtime that can damage an unprotected generator. The Cummins Onan service documentation recommends winterization for any storage period exceeding 30 days.

TL;DR

Generator winterization covers fuel stabilization, oil change, and storage prep ($95-175), or full generator plus RV winterization ($175-350). We handle everything on-site so your generator is ready when you are.

What's Involved in Winterization

1

Inspect Fuel Quality

We pull a fuel sample and check for discoloration, water contamination, and that telltale varnish smell that indicates stale gas. This tells us whether we need a simple filter swap or a full system flush.

2

Replace Fuel Filter

The inline fuel filter gets swapped for a new one. On diesel generators, we also check and drain the water separator if equipped.

3

Clean the Carburetor

We remove the carburetor, disassemble it, soak the body and jets in carb cleaner, blow out all passages with compressed air, and reassemble with new gaskets.

4

Test and Tune

With fresh fuel flowing through clean components, we start the generator and adjust the idle mixture if needed. We run it under load to confirm smooth, surge-free operation.

Generator Winterization FAQs

How much does RV generator fuel system cleaning cost in Palm City?

Fuel filter replacement runs $45-95, carburetor cleaning costs $125-250, and a complete fuel flush is $150-275. The exact price depends on your generator model and how badly the system is contaminated. We'll give you a number before starting.

How often should I clean my RV generator's fuel system?

Fuel filters should be replaced annually or every 400 hours. Carburetor cleaning is needed when you notice starting or performance issues. The best prevention is running your generator for at least 2 hours every month and using fuel stabilizer if it'll sit longer than 30 days.

Can stale gas damage my RV generator?

Yes. Gasoline starts degrading after about 30 days, especially ethanol-blended fuel in Florida's humidity. The ethanol absorbs moisture, which causes corrosion in the carburetor, fuel lines, and tank. Varnish deposits from old gas clog tiny jets and passages. We've seen generators that needed complete carburetor rebuilds because they sat with untreated fuel for a single summer.

Should I use fuel stabilizer in my RV generator?

Absolutely. If your generator will sit unused for more than 2-3 weeks, add stabilizer to the fuel. Products like Sta-Bil or Sea Foam prevent oxidation and moisture absorption. Add the stabilizer, then run the generator for 10-15 minutes so treated fuel circulates through the entire system including the carburetor.

My generator surges under load. Is that a fuel system problem?

Surging is often a fuel delivery issue. A partially clogged main jet in the carburetor, a weak fuel pump, or a restricted fuel filter can all cause the engine to hunt for the right fuel-air mixture under load. It could also be a governor adjustment issue. We'll diagnose the root cause on-site.

Can you service diesel generator fuel systems too?

Yes. Diesel generators have different fuel system components including fuel injectors, injection pumps, and water separators. We service all diesel generator brands and can handle filter replacement, water separator draining, fuel polishing, and injector cleaning at your location.
