When it comes to choosing a generator there are many factors that come into play. There are certain things you should be aware of about gas and diesel powered generators to help you make a decision regarding which type of generator best suits our needs. Each has their own advantages, but we feel that diesel powered generators are the better choice, and I will elaborate on this below.
Diesel powered generators have many advantages of gas powered generators. Here are 4 of the main advantages:
Energy Density – For the most part, gasoline is cheaper than diesel fuel, but diesel engines have a higher energy density. What this means is the same amount of gasoline and diesel fuel will produce different amounts of energy. Diesel fuel will will extract a higher amount of energy than gasoline, and it is a large enough amount to be considered significant.
Life Expectancy – A diesel generator is going to last you much longer than a gas generator will, that is just a fact. In fact, a properly maintained diesel powered generator can last well over 10 years. The reason they are so much longer is because gas powered generators run at extremely high RPM, while diesel runs lower, which puts less stress on the generator.
Maintenance – There are no spark plugs or spark wires to change in a diesel generator. This will not only mean less maintenance, but lower maintenance costs as well.
Durability – Diesel generators are built more rugged and reliable than that of gas. So when you are transporting you do not have to worry about the unit being damaged from the slightest of bumps.
The modern diesel generators have overcome many of the disadvantages they had from years past. Older models used to be loud, and cost more to maintain, however, that is no longer the case. Now you can count on a diesel generator to be no more noisy than gas, and it will cost you less to maintain than gas. The only advantage, and I am hesitant to call it an advantage is cost. Gas generators are generally cheaper upfront, but in the long haul they will cost you more money in fuel cost, maintenance, and you will have to replace it much sooner than a diesel generator.
Overall, there really is no debate on this topic. Diesel generators are a much safer choice if you are looking for a back up power source, whether it is for your home or for on the job.
