Are Diesel Generators Better Than Petrol Generators?

Eastern-Generator-Hire 0397390938

Petrol generators are less common as diesel generators become the more reliable option. Diesel generators are often more expensive than petrol, but they provide many benefits that may outweigh the price difference. It can be difficult to make the best decision when there is so much conflicting information out there about these two types of generators.

The best generator for you needs to be able to meet your requirements because if a generator is considered the best for someone else, it might not be for you. To discover your perfect generator, you’ll need to decide between the features of petrol and diesel as an alternative source of power.

Diesel Generators

A diesel generator uses the power from an internal combustion engine to provide electricity. A motor turns a crankshaft which powers pistons that create heat and pressure inside the cylinders. This heat and pressure turn the fuel into a mist that is then burnt to create energy. The exhaust from this combustion creates more power which goes through an alternator creating electricity.

What are the benefits of diesel generators ?

Diesel generators provide many unique benefits such as:

Fuel Efficiency

Diesel generators can produce more power than petrol generators because the fuel efficiency allows them to last longer per tank of diesel which means that they will run for a longer amount of time without needing to be refilled or any other maintenance work. This makes these types of generators great choices if you are going to be using it for a long time.

Durability

Diesel generators are known for being more durable than petrol generators. Diesel generators are built with rugged and heavy duty parts and materials that protect the internal parts such as the diesel engine from wear and tear which means you’ll be able to use these types of generator for a longer time without having any issues. This means that you’ll likely require less repairs in the future as they are made to withstand many conditions and are built to last.

Wide Range of Features

Diesel generators provide many features that are great for specific purposes. Some of these include:

Large Fuel Tanks

If you plan on using your generator for a long time, then diesel generators with larger fuel tanks will last longer than petrol generators which need refilling often. This is perfect if you’re going to be away from power for extended periods of time.

Powers Multiple Electric Devices

Diesel generators are the way to go since they can power more than just one device at a time. This means that it will be able to handle large appliances without having any issues working with them.

Noise Level

Depending on the type of diesel generator you choose, it can have additional features such as being a silent generator. This doesn’t mean that they’re silent, but the generators can be super quiet operating at around 50 to 60 decibels which is as loud as a conversation in an office or a restaurant. You should note that diesel generators are generally considered louder than petrol generators, so depending on the one you choose they can run quieter when you need them to.

Disadvantages of Diesel Generators

High initial upfront cost

If you’re planning on buying a diesel generator, they are more expensive than petrol generators. They are made of high quality parts to make the machine durable and long-lasting. Diesel generators come in a range of different sizes from more small and portable generators to larger industrial generators.
If you’re looking to use a high-powered diesel generator for a short period as a temporary alternate power source, you can look at hiring a generator from Eastern Generators. We have a range of different sized diesel generators for hire including silent generators. Get in touch with us to enquire more about our generator and services

High maintenance and repair costs

Another disadvantage of diesel generators is that they require higher maintenance and repair costs than petrol generators. This means that you’ll have to spend more money in the long run for keeping it running smoothly which can add up quickly if you’re planning on using your generator for many years.

Petrol Generators

A petrol generator uses a small internal combustion engine to run an electrical generator. The fuel is mixed with air and burnt inside the cylinder causing it to expand. This expansion creates pressure that pushes pistons down which then turn crankshafts creating energy through electromagnetic coils which produce electricity for use by your appliances, tools and any other electrical components of your home or business.

Although petrol generators are generally less popular, they do have some advantages that diesel generators don’t. These include:

Price

Petrol generators tend to be cheaper than their counterparts which makes them a great choice if you’re operating on a budget or need something for occasional use. Petrol is also easier to find than diesel which is why these generators are perfect for outdoor activities like camping.

Portability

Petrol generators are generally much smaller than diesel which means that they’re easier to store and transport. This makes them great for someone on the move or who needs a generator on-the-go, especially if you need to take it with you often. These are particularly useful for outdoor leisure activity and powering small electrical appliances.

Less maintenance

Petrol generators are generally less expensive to maintain than diesel generators which is another reason why they’re great for occasional use. They require little to no maintenance at all which means that you can just set it up, turn it on and use your appliances without having to spend money for repairs or upkeep.

These types of generators also have some disadvantages that you should know about. These include:

Fuel Consumption

Petrol generators use petrol as fuel which means that they need to be refilled often, making them less efficient and more expensive in the long run.

Lack of Power

Although petrol generators are cheaper than diesel generators, they’re generally not as powerful when it comes to high-power requirements. If you need a generator for a large amount of appliances or devices, petrol generators will struggle in this situation and may not be able to keep up with your electrical needs.

Choosing a Generator

To decide on which generator to go with, you need to consider how you’ll be using your generator. Before purchasing or hiring one, make sure that it’s the right machine for you and make a note of what tasks or appliances that you’re planning on powering with it. You also want to decide whether diesel is worth the extra cost over petrol before investing in a new generator; this will save you money later down the line.

Determine the most important features you’ll need your generator to have. If you require a temporary power solution for an event to power multiple electrical devices such as sound and lighting, then you may like to consider a portable diesel generator that has enough power for your event and quiet enough that it won’t disrupt your guests.

If you require your generator to power more than small equipment, appliances or for leisure activities, you might want to consider hiring or buying a diesel generator over petrol generators. Read more on hiring or buying a generator if you’re unsure about what situation is better for you.
