How to Maintain Gas Powered Generators for Optimal Performance

Gas powered generators are a reliable and efficient source of backup energy for homes, businesses, and outdoor setups. But like any machine, they need regular care to keep them running at their best.

In this blog, we’ll walk you through simple steps to maintain your gas generator and ensure it performs well for years to come.

Why Generator Maintenance Matters

Routine maintenance helps prevent breakdowns, extends the life of your generator, and keeps it working efficiently. It also ensures your generator is ready to go when you need it most—especially during power outages or emergencies.

Check the Oil Regularly

Just like a car engine, gas generators need clean oil to run smoothly. Dirty or low oil levels can cause damage or reduce performance.

• Check oil levels before each use, or at least every 8–10 hours of operation.
• Change the oil according to the manufacturer’s recommendations—usually every 50–100 hours of use.
• Use the right type of oil for your model and climate.

Tip: Keep spare oil and a funnel handy so you’re not caught off guard.

Keep the Air Filter Clean

A clean air filter ensures your generator breathes properly and burns fuel efficiently. You should inspect the air filter every 25 hours of use and clean or replace it if it appears dirty, dusty, or clogged.

To maintain optimal performance, always use the filter type recommended for your specific generator model.

Inspect Spark Plugs and Fuel System

Spark plugs play a key role in starting your generator and keeping it running. Over time, they can wear out or get dirty.

• Check spark plugs every 100 hours of use.
• Replace them if they look damaged, corroded, or covered in carbon build-up.

For the fuel system:

• Use fresh, clean petrol. Old fuel can cause clogs and poor performance.
• Add a fuel stabiliser if your generator will sit unused for a long time.
• Drain the fuel tank if you won’t be using the generator for more than a few months.

Run Your Generator Regularly

Even if you don’t currently need backup power, it’s a good idea to run your generator for 10 to 15 minutes every few weeks. This short exercise keeps the internal parts lubricated, helps prevent fuel from becoming stale, and ensures that the battery (if your unit has one) remains charged and ready to go.

Regularly running the generator also gives you the chance to spot any unusual noises, leaks, or performance issues early—before they turn into costly repairs or leave you without power when you need it most.

Store It Properly

When not in use, store your gas powered generator in a clean, dry, and well-ventilated area.

• Cover it to keep out dust and moisture.
• Keep it away from direct sunlight or extreme temperatures.
• Make sure it’s fully cooled down before storing.

Schedule a Professional Service

While many tasks can be done at home, having your generator professionally serviced once a year is a smart move.

A technician can:

• Perform a complete inspection
• Check electrical components
• Spot wear and tear you might miss
