Frequently Asked Questions About Petrol Generators

What size petrol generator do I need?

The size depends on your power requirements. For home backup, a generator between 3kW and 5kW is usually sufficient. For farms, workshops, or construction use, consider 6kW or higher to handle heavier tools and multiple appliances.

Are petrol generators fuel-efficient?

Yes, modern petrol generators are designed for fuel efficiency. Models with Loncin engines or automatic voltage regulation (AVR) offer longer runtime and smoother performance while using less fuel.

Can I use a petrol generator for home backup?

Absolutely. Many petrol generators are ideal for home use, especially models with 3–5kW output. They can power essential appliances like fridges, lights, and heating systems during power outages.

What’s the difference between petrol and diesel generators?

Petrol generators are generally quieter, more portable, and easier to start, making them ideal for domestic or light commercial use. Diesel generators are heavier but offer longer runtime and durability for industrial applications.

How do I maintain a petrol generator?

Perform regular oil checks, keep air filters clean, and run your generator periodically to prevent stale fuel build-up. Always use fresh petrol and store your generator in a dry, ventilated space.
