If you’re looking at getting a new vehicle or have ever pondered the difference between diesel and petrol fuel, we’re here to give you some answers. Both are very popular ways to power vehicles, but which one is better? Why are big trucks diesel powered? And what are the benefits and drawbacks to each type of fuel? 

Gasoline, or Petrol, is the most commonly used type of fuel. Gas engines are typically easier and cheaper to fix, are more forgiving if you run out of fuel, and are typically quieter. These are all traits that most people really like to have in a day to day use vehicle, which is part of why it’s so popular. 

So what are the drawbacks to Gasoline? Well, their efficiency is the biggest drawback, which means you’re filling up more often than a diesel vehicle. The fuel itself is also more detrimental to the environment releasing 20% more CO2 into the atmosphere than diesel. Gas also gets outshined when you want to sell your car, as gas powered vehicles tend to depreciate faster than diesel. 

Diesel engines on the other hand are significantly more fuel efficient, using 30% less fuel than its gasoline counterparts. Not only that but as the stroke length is longer, they also have more torque for pulling heavy loads. These are the main reasons why semi trucks and heavy machinery use diesel more often than not. They may be more finicky to take care of, but it pays off in the long run.

The cons from diesel come from the cost and noise. These engines are loud and are much more expensive to fix if something does go wrong under the hood. If you make a mistake with a diesel engine and run it out of fuel or, heaven forbid, you accidentally fill it with gas, you will probably have to get yourself a new vehicle or face a costly repair. So next time you’re looking for a new car keep these facts in mind and make sure you choose the right option for yourself.
