Diesel vs. Petrol


There are two main types of fuel for vehicles, petrol and diesel. They are rather different, which is why you can’t use them interchangeably, but which is better? That depends on the end use.

Here’s what you need to know about each fuel type.


One of the biggest reasons to use diesel is the fact that it is more efficient than petrol. It reduces your carbon footprint considerably, so if you’re environmentally minded, this is a better choice simply for that reason. It’s also less likely to fluctuate in price.

Diesel allows you to drive much further with a tank full of fuel, as well. This makes it more economical in some ways. This means you’ll save a considerable amount of money and drive further on a single tank of fuel.

The engines designed for diesel are often used in heavy duty machines and vehicles for good reason. They’re stronger and better for managing heavier loads. Diesel engines have more torque, so you know they’re meant for hard work. These engines are usually more cost effective than petrol engines, as well.

Since these engines are simpler, they’re much simpler to work on and can be fixed with simpler options.

Diesel engines have no sparkplugs and they don’t require tuning. This simplicity is often what helps make them popular. However, they do tend to cost more for parts, though they are simpler. While they may last longer than petrol engines, when they do need to be repaired, the cost is considerably more.

Despite being more eco friendly overall, diesel does have an issue with putting some harmful gases out if the particulate filter gets clogged. There’s also no real fuel benefit when driving in urban settings.


While petrol may be lower cost, it doesn’t get the same fuel efficiency on the highway as diesel. It is certainly just as efficient in the city, though.

While petrol has higher CO2 emissions, it also produces less particulate emissions and in general, petrol vehicles are quieter to run. This may be an issue, depending on where you live. It may be more efficient in town, but there are plenty of reasons to use diesel.

Which Option is Best?

Both types of engine cause some sort of pollution, but diesel engines have filters in place to prevent particulates from escaping. If you’re looking for the most cost effective vehicle to run in general, you’ll want a diesel engine. In many cases, diesel outshines the petrol vehicle, but everyone has their own preference. What’s yours?
