The new car buyer is faced with many different questions when shopping for a new vehicle. However, one of the most fundamental issues of all what is the best gas for your car to run on. For a majority of individuals, the choice is a simple one of either diesel or petrol. However, depending on what your motoring habits are, an electric or hybrid car might just be the perfect thing for you.

It isn’t easy to make the right choice and choosing the best gas for your car. There are many different factors for you to consider. These include:

  • How easily you will be able to live with the particular car
  • The kind of driving you tend to do
  • Other operating costs, including depreciation and tax
  • Fuel economy

The following are the major Pros and Cons of the four major types of fuel choices:


Pros: Petrol is less expensive than diesel; in addition, petrol cars tend to cost less than equivalent diesel cars.

Cons: Petrol cars tend to lose their value more quickly; diesel vehicles are more economical.

The most popular choice for choosing the best gas for your car in the UK is the petrol engine. There are several good reasons why this is the case. For starters, petrol is less expensive than diesel is; petrol-engine vehicles also tend to be less expensive than equivalent diesel cars.

However, the advantages have to be offset with the fact that petrol vehicles aren’t as economical as diesel ones are; and, especially with larger vehicles, petrol models tend to lose their value faster.

However, overall, for somebody that has a fairly low annual mileage of not over six to seven thousand miles- then the best choice will most certainly be a petrol car.

Best For: Drivers wanting to have a fairly small vehicle whose annual mileage is low to medium.


Pros: Diesel vehicles are more economical, cheaper to tax and feel easier to drive than petrol cars.

Cons: Fuel is more expensive to purchase; particulate filters are expensive to repair.

A diesel vehicle might make more sense if you have a higher mileage. Diesel vehicles are 15 to 20% more efficient compared to equivalent petrol models. As your mileage increases, you get to the point where the savings in fuel costs make up for the added fuel and car costs initially.

You might have also heard that high local pollutant levels are produced by diesel engines. Although that was true in the past, the most recent diesels all meet the Euro 6 emission standards, with 99% of the total particles being removed from out of the exhaust.

However, one disadvantage that modern diesel engines have is that they normally work using a particulate filter. Those need to have regular long drives in order for them to continue working properly. If you stay close to town, your filter might get clogged up and eventually fail. Replacing them is expensive.

Best For: Those who put high mileage on their cars, especially if a lot of it is motorway driving.

Electric Car

Pros: Responsive to drive, quiet, low operating costs.

Cons: Expensive to buy, awkward to recharge at times, limited range.

These are not only as well-equipped and classy as regular cars; they are also very inexpensive to operate. They are exempt from London’s congestion charge, charging costs are inexpensive and they have low tax liabilities. In addition, electric cars are very enjoyable to drive.

The problem is majority of people won’t go over 100 miles before needing to be recharged, and they might not even go that far. The range may be significantly reduced if you are driving in cold weather, switch many electrical items on, or drive your car hard.

What is even worse, it isn’t very easy to recharge electrical cars compared to a diesel or petrol car. You will need to plan ahead in choosing the best gas for your car and make sure that you schedule recharging on a regular basis. Finally, electric cars are fairly expensive to purchase, even with the government grant that you may be eligible for.

Best For: Drivers with easy access to a charge facility and who don’t drive many miles at one time.


Pros: Can be inexpensive to tax and operate; combines a greater range with some all-electric driving.

Cons: Plug-in hybrids need charging facility access; can be expensive to buy; most beneficial for town driving.

If a pure electric car is something you can’t live with, there is still a potential solution that will provide you with some zero-emission driving: a hybrid combining an electric motor with a conventional diesel or petrol engine.

You can enjoy all-electric motoring whenever the battery is charged. However, the conventional engine also provides you with a longer range as well as greater flexibility in terms of being able to fuel up in a few minutes at a fuel station.

However, hybrids can be fairly expensive to purchase. Also, to take complete advantage of all of the benefits they provide, you will need to spend lots of time driving at low speeds, which generally means in town. Individuals with high mileage needs will almost always be better off getting a diesel. If the latest plug-in hybrids appeal to you, which have longer range using electric power and larger batteries, you will need to have access to a charging facility.

Best For: It would be the best gas for your car if you spend lots of time driving around town and in fairly low mileage.
