How to Keep Your RV Generator in Pristine Condition?
To make sure that your RV’s generator stays in perfect working condition and keeps powering your onboard appliances flawlessly, you have to take care of it and stick religiously to the manufacturer’s recommended maintenance schedules. Follow these tips to get the maximum out of your RV generator:
Maintenance and oil change
The maintenance of an RV generator is similar to any other engine. It involves cleaning the air filter, changing the engine oil and filter on time, and servicing the spark plug.
Getting rid of any corroded part or rusted panel, and replacing any faulty wires or hoses also keep the generator in mint condition and prevent unnecessary faults over time.
Keeping an eye on all the filters, oil levels, and other mechanical parts is also crucial. It helps avoid major problems and helps you diagnose any issues timely.
Do not overload
Another important consideration that most RV owners ignore is running everything together on their generators. This overloads the engine which can cause overheating and damage the engine.
Try to use only compatible appliances and don’t overburden your generator. It could hamper its performance and possibly kill its lifespan.
Fix the issues promptly
If you even get the slightest symptom or hear an unusual sound from your RV generator, get it checked and fixed immediately. Timely action could prevent any major damage and save you a lot of time and mental agony.
How Long Can You Safely Run an RV Generator?
With any combustion engine in question, no machine should be left unattended while running, let alone for hours. There is a limit to how long an RV generator can be used safely, and it is generally considered to be 8 hours.
Most RVs usually have a generator as their only power source and with so many appliances running, you wouldn’t want to give your RV generator a break. Yeah! Who would want the music to stop or drinks to go bad by turning off the fridge and other onboard systems?
We strictly suggest against this and recommend that you should not keep your RV generator running for more than 8 hours straight. In case you have to, it’s better that you give it some breaks in between and switch off the unnecessary appliances.
Running your RV generator non-stop could overheat the engine, burn the wiring or fuses, and even lead to a fire hazard if things get out of hand. So be cautious about it and put a cap on your RV generator run time.
How Often Should an RV Generator Be Serviced?
An RV generator must be maintained like a car, as there is not much difference in the engine of both machines. Regular servicing ensures optimal performance, reduced emissions, optimal power output, and reduced malfunctions.
As per most manufacturers, an RV generator should be serviced every 1,000 hours or 8 months, whichever comes first. This timeline could differ based on the oil type you use, as fully synthetic engine oils have extended lifespans and offer longer change intervals.
You must stick to your manufacturer’s guidelines and get your RV generator serviced regularly to have the best time in the outdoors and enjoy your camping trips to the fullest.
How to Make Your RV Generator Run Efficiently?
With proper planning and smart usage, you can actually churn out more hours out of your RV generator with the same gallons of fuel.
Here’s how you can make your RV generator run longer and more efficient;
- Use fully synthetic oil in your RV generator and keep the air filter clean.
- Use premium fuel, like RON 92 or above, as these have fewer impurities and offer more efficiency.
- Do not run more than 3 appliances at once and turn off the unnecessary gadgets instead of putting them in sleep mode.
- Keep your generator in a well-ventilated area to avoid overheating.
- Look for any leaks, hotspots, or shorts, and get them fixed.
- Flush the engine oil during maintenance and use an internal coating for seamless combustion.
Can an RV Generator Run on Propane?
If you’ve run out of gas and looking for a way out, you could use propane to fire up your RV generator. Although an RV generator can run on propane, it won’t nearly be half as efficient as gasoline or diesel.
Having propane in your RV is good but don’t take it as your routine alternative fuel and must pack an extra jerry can of gas for the generator.
It’s possible doesn’t mean it is advisable and running an RV generator on propane for longer can take a toll on its efficiency and long-term durability as well.
