A generator is a fantastic piece of equipment, serving as a dependable power source during unexpected outages and ensuring uninterrupted operations for homes and businesses. Due to these reasons, many people are buying generators, and global generator sales are expected to reach USD 42.29 billion in 2029.

However, to ensure that your generator continues to perform at its best when you need it most, proper maintenance is essential. Neglecting this point results in generator breakdowns at the most inconvenient times, leaving you without power when you need it the most. For instance, the cost of a Generac generator may be attractive, but poor maintenance habits will force you to spend more than the buying price.

This article discusses some of the best generator maintenance tips you should follow to ensure the longevity of your powerhouse. Let’s dive in!

Tips To Maintain A Generator

When purchasing a generator for your home or business, consider the wattage requirement, cost of the generator, and maintenance costs. Not spending enough on maintenance can lead to additional costs. So don’t neglect regular maintenance.

  1. Change Generator Oil

First and foremost, you should regularly change your generator oil for optimal engine health. It’s because neglecting oil changes can lead to engine wear, reduced efficiency, and even engine damage.

However, how often to change generator oil depends upon the brand of your generator, usage frequency, and the running environment. On average, the recommended frequency for oil changes falls between 50 and 200 hours of operation.

Tip: Always check the oil level with the dipstick and dispose of the old oil responsibly.

  1. Keep The Generator And Its Surroundings Clean

Keeping your generator and surroundings clean is crucial for its safety and efficiency. You should regularly wipe down the generator’s exterior surfaces with a damp cloth to remove dirt and debris. Don’t forget to inspect for rust or corrosion, addressing any issues promptly to prevent structural damage.

Keep the area around the generator free of leaves and debris to ensure proper ventilation and prevent blockages that can hinder its operation. Also, be vigilant about checking for pests or insects that may reside near the generator, potentially damaging its wiring and components.

  1. Check All The Wirings

Another generator maintenance tip is to check all the wiring in your generator. Proper wiring is essential for the generator’s performance and safety. Therefore, instead of simply inspecting, regularly examine cords, cables, and the control panel for any visible damage or loose connections.

Pay close attention to the warning lights on the control panel, as they can indicate issues with the wiring of the generator. To ensure a thorough assessment, it’s a good practice to schedule professional maintenance by a qualified technician.

  1. Replace Air Filter

A clean air filter ensures proper airflow to the engine, which is crucial for efficient combustion. When it becomes clogged with dirt and debris, it can lead to reduced performance and increased fuel consumption.

Hence, inspecting your air filter for any clogging and replacing it at recommended intervals to maintain optimal engine efficiency is essential. This ensures your generator stays in the best health without compromising power output.

  1. Timely Remove All Worn Out Or Damaged Parts

One of the best maintenance tips for your generator is to remove worn-out or damaged parts. Components like spark plugs, drive belts, and hoses can deteriorate over time. If you notice cracks, fraying, or diminished performance in any of these parts, replace them promptly. It’s because neglecting to replace worn-out components can result in more extensive and costly damage to your generator.

  1. Check The Fuel System

Diesel, as fuel in the generator, makes your generator’s fuel system susceptible to contamination and corrosion within a minimum of one-year timeframe. The best solution to avoid this is to ensure you use fresh and stabilized fuel. On top of that, keep the fuel tank clean and free from contaminants.

Also, check fuel lines and filters for blockages or leaks. Remember, running your generator with clean fuel and a well-maintained fuel system is critical to preventing engine problems.

  1. Store The Generator Properly

Lastly, storing your generator safely is paramount to ensuring its long-term reliability. To begin with, choose a designated storage area that is dry and well-ventilated to prevent moisture buildup, which can lead to rust and corrosion.

It’s essential to keep the generator protected from extreme temperatures and direct sunlight, as these can negatively impact its components. Furthermore, empty the fuel tank and fuel lines to make sure there’s no chance of contamination.


Maintaining your generator is not only a matter of convenience but also a critical step in ensuring its functionality during power outages and emergencies. Regularly checking wiring`, replacing the air filter, promptly addressing worn-out parts, monitoring the fuel system, and storing the generator properly are key practices that can prolong its lifespan and guarantee dependable performance. So, stick with these tips for a smoothly working generator for years!
