Petrol vs. Diesel Engine: Which Is Better?

Tax season is usually a smart time to buy a new car. You have the extra cash, plus dealers offer seasonal discounts around this time of the year. 

Advancements in Ecotechnology allow you the option of choosing your fuel power type. In the battle of petrol vs. diesel engine, which is better for you?

Choosing a fuel type for your new vehicle has a lot to do with cost savings and other benefits. Some octane types offer better fuel economy, while others fall short the distance.

You also have to weigh in greenhouse gas reduction (GHG) and torque performance. 

Wondering what’s going to be best for your type of motoring for the environment and your wallet? Well, read this. Learn about petrol vs. diesel engines to make the right decision for your needs.

What is Petrol Engine?

Most cars on the road have gas-powered engines. In fact, motor gasoline consumption in the U.S averages about nine million barrels a day. 

So what is a petrol engine? It’s any vehicle with an ICE—internal combustible engine. Basically, a car that runs off gas. Although, some cars use a gas mixture that includes ethanol.

Power generates in these engines by burning gas ignited by an electric spark. 

Diesel Engine Explained

The diesel engine earned its name from Rudolph Diesel—inventor and mechanical engineer. It’s also a type of internal combustion engine. However, it’s powered by intermittent combustion.

Because of mechanical compression, the air temperature in the cylinder raises causing diesel fuel to ignite. 

As the thirst for larger vehicles escalates, so do diesel sales in the U.S. Last year, consumers bought 50,000 more diesel engines—pickup trucks and SUVs. People find convenience in diesel, especially with today’s commercial fuel delivery options.

Petrol vs. Diesel Engine: Pros and Cons 

Both petrol and diesel are viable options when choosing a new vehicle. But, they don’t come without their share of pros and cons. 

Pros of the Petrol Engine

  • Money matters and petrol is the cheaper choice. The vehicle options, price of fuel, and servicing costs are less expensive than its diesel counterpart.
  • Petrol-powered vehicles have a quieter engine. That alone offers a better driving experience on the road.
  • For stop-and-go type driving, as well as short trips, petrol engines win out over diesel.

Pros of the Diesel Engine

  • Diesel engines burn less fuel due to their type of combustion. That makes the running costs slightly less expensive than petrol.
  • The environment survives diesel better than petrol in that it emits less carbon dioxide.
  • Diesel also burns slower, so you get better gas mileage. 

Cons of Petrol

  • Most petrol-powered vehicles burn a lot of gas, dipping into your wallet a bit more.
  • Petrol discharges more carbon dioxide in the environment than diesel.
  • Gasoline burns fast, so petrol cars get fewer miles to the gallon. 

Cons of Diesel

  • Diesel fuel costs more than petrol. 
  • Diesel emits particles in the air that are dangerous to those with certain breathing conditions. 
  • Diesel is louder in larger vehicles like 16-wheelers and trucks. The larger the vehicle, the louder the driving experience. 

There’s quite a bit of information to process before choosing between these two engine-types. The pros and cons are encouragement enough to think things through so you make the right decision.

Choose the Right Type

Again when you’re choosing the right type of motoring, you must consider the environment, your finances, and your desired driving experience.

Weigh the pros and cons to help you make the smart choice.
