3 Common Types of Fuel for Generators

Posted on

A short-term power cut has the potential to cause a significant amount of inconvenience to everyone. In order to keep the power supply running, there are several types of generators that run on different fuels. Let’s take a look at the three of the most common options:


Generators that run on gasoline are the most popular option. A few of the key reasons for this is the relatively low-cost and the fact gasoline is widely available. However, it can be difficult to source in times of a power cut because its pump system relies on electricity to work. Most of the gasoline generators are portable and small in size. Also, it is essential this type of fuel is stored appropriately because it is highly flammable. Gasoline stored in the correct manner has the potential to last up to 12 months. A further issue that may influence the use of this type of generator is the difficulty in starting in cold temperatures.


Diesel is a much safer source of fuel to use in the generator. It is just as readily available as other fuel options like gasoline and is available to certain industries like farming at reduced tax rates. Diesel generators have the potential to last for the long-term and run very efficiently. Also, they are a much more reliable option to run in cold weather. However, there are issues with the lifespan of the diesel fuel. In most cases, this has the potential to last for a maximum period of 24 months. A further point to consider is the environmental concerns. Diesel engines emit the relatively high emissions and this can limit the use of this generator. Also, it may not be a practical option for wet environments, such as outdoors in the elements or near rivers or lakes because moisture can have a negative impact on this fuel.

Propane gas

Propane gas (liquid or vapor) is a very clean burning fuel that lasts much longer on the shelf compared to alternatives like diesel and gasoline. Most of the generators that accept propane are relatively affordable. Also, this type of fuel does not have a problem in cold temperatures. However, there are a few negative issues with propane. A major concern is the fact this fuel is very flammable and is kept under pressure. Plus, the basic fuel system is more complex than the other options which will mean the setup and installation is a more difficult process. The volume of fuel used is also higher. On average, the propane generator will use nearly three times more fuel than a diesel unit.
