Should I Lease a Petrol or Diesel Car?

15 Jan 2021

In this article, we are going to discuss some important information about leasing both petrol and diesel cars, and the pros and cons of each option.

You might be thinking that your choice of leasing either a petrol or diesel car is primarily only down to the price and whichever one produces the best deal. However, there are many other factors that you should take into account when leasing either a petrol or diesel car, such as your needs and requirements, and environmental impact. 

In this article, we are going to discuss some important information about leasing both petrol and diesel cars, and the pros and cons of each option.

Petrol Cars

When choosing to lease a petrol car, you should consider whether you will be driving around more urbanised areas. If you do live and work in urban areas, then leasing a petrol car is definitely the best option for you. This is because petrol vehicles are much better suited for shorter journeys. 
As petrol cars are more suitable for those that drive shorter distances, you will find that petrol is also cheaper at the pump than diesel. This also means that the petrol equivalent of a diesel car will be cheaper to lease too.
As well as petrol cars being cheaper to lease and run, you will find that the driving experience is smoother in comparison to a diesel car. Therefore, a petrol engine is much quieter when being driven.
Now, even though leasing a petrol car has all these advantages, there are some downsides. For example, the fact that petrol cars produce a much larger amount of CO2 emissions compared to diesel cars. In fact, according to the Society of Motor Manufacturers and Traders (SMMT), the average CO2 emissions produced by petrol cars increased by 2.9% in 2018 and by a further 2.7% in 2019. Therefore, choosing to lease a petrol car means you will be contributing more to the effects of global warming. 
Of course, there are now a number of options for leasing an electric vehicle but these can be pricier. So, if an electric vehicle is out of your budget but you think leasing a petrol car will suit you better than diesel, you should consider leasing a car with low CO2 emissions.
Summary of points to consider when leasing a petrol car:


They are more suitable for drivers who travel only a low amount of miles and live in the city.

They cost less to lease and run than diesel cars.

They are quieter when driving than diesel cars.


They produce higher CO2 emissions than diesel cars.

Their fuel economy is lower on longer journeys.

Electric vehicles are becoming more popular which means petrol cars will fizzle out.

Diesel Cars

Alternatively to leasing a petrol car, leasing a diesel car is most likely going to be much more economical for you if you travel a significant amount of miles yearly. In fact, according to SMMT, diesel cars cover 60% more miles than petrol cars.
Even though leasing a petrol car means you are contributing largely to the production of CO2 emissions, this doesn’t mean that leasing a diesel car won’t create the same effect. However, leasing a newer diesel car could be much more economical for you than leasing either an old diesel car or any petrol car. 
This is because all new diesel cars must now meet the Euro 6 emission standards which requires them to feature a Diesel Particulate Filter (DPF) which captures and burns at least 99% of the sooty particles that diesel engines produce when being driven. This also reduces nitrogen oxide (NOx) emissions. Even though this means leasing a diesel car could be more economical, it does mean that diesel cars need longer running times to warm up so the DPF filter doesn’t get clogged. On top of this, cleaning the filter can be costly.
As well as meeting Euro 6 emission standards, all petrol cars bought or leased from January 2021 must also meet RDE2 (Real Driving Emissions) standards. Meeting these emission standards ensures that your diesel fuelled car has met the standards on both the road and in the laboratory. 
If you are leasing a diesel car that meets RDE2 standards and is for business purposes, an advantage is that you get to pay less Vehicle Excise Duty and Benefit In Kind company car tax. As well as tax savings, you can also save on time as diesel cars feature a higher engine torque than petrol cars. This means you can reach high speeds from low speeds in much quicker time and the transition is much more relaxing.
Diesel cars also have CO2 emissions that are 15-20% lower on average than petrol cars and they are more fuel efficient compared to petrol cars. However, this means that when leasing a diesel car, you’ll find yourself paying more to fill it up at the pump each time as filling up won’t be so often.
Summary of points to consider when leasing a diesel car:


They are suitable for long distance drivers, such as those driving for business and not living in urban areas.

They are more economical to run and produce fewer CO2 emissions than petrol cars.

They are relaxing to drive due to their engine torque.


They are usually more expensive to lease and run than petrol cars.

There are not suitable for drivers in the city that produce low mileage per year.

They produce a louder sound than petrol cars.
