Diesel generators can be more expensive than petrol-powered generators but there are numerous advantages that make them attractive to small and large businesses. Here, we put together the reasons as to why you should buy a diesel generator.


Less Maintenance: It is known to have low maintenance compared to its counterpart. Diesel generators require fewer components to start so you don't have to worry about changing spark plugs or carburetors as you would with the petrol-powered ones

Fuel Efficiency: With the same amount of work as a petrol generator, a diesel-driven generator tends to consume less fuel which makes the diesel generator a cheaper investment in the long run.

Durability: Diesel engines are extremely tough in that they can hold wear and tear in a variety of environmental conditions.

Longer Lifespan: Diesel generators are known to outlast any other types of generators available. This is because the diesel engines are made of simpler and slower moving parts so their mechanical pieces do not rub together as typically do with the petrol ones. As such diesel generators won't wear out as soon.


For an average Australian home, the KVA required should be at least 3 KVA to 7 KVA.

With this power from a generator or battery power station, you will comfortably be able to run all your household appliances.

Improvements and innovations to technology used in generators enables a diesel generator to no longer be considered dangerous for computers, televisions and sensitive electronic equipment. 

The key is to ensure that the generator can provide clean electricity: that the voltage and current is steady, rather than being prone to surges or spikes.

The types to choose from are diesel or petrol? Inverter or not inverter? Air cooled or water cooled?

Diesel generator is cheaper to run and longer lasting.

Inverter generators will not harm sensitive electronics such as TVs and computers but generally are less powerful and mostly petrol.

Water cooled diesel generators last longer and a quieter but generally more expensive to purchase in the first place.

In 1958 the Rolls-Royce Silver cloud would have cost you almost 3 times you're yearly wage what a beautiful piece of machinery and would still be working beautifully today however you would be trying to source leaded fuel and the fuel economy of that engine would be shocking in today's fuel prices. However a Ford would have cost 1/4 or less than the Rolls-Royce and you would have replaced it many times with a cheaper current car which kept on getting more fuel efficient, more modern gadgets and getting cheaper every decade, so paying big dollars for a name brand can be a false economy.
