Petrol or Diesel

Diesel vehicles have always been the most popular vehicles amongst drivers, thanks to their low road tax and their superior fuel economy, but has the tide changed?

With diesel motorists now paying the same in road tax as their counterparts driving the petrol alternatives, the emissions that diesel vehicles are giving off and the lower residual values that diesel vehicles are getting when it comes to finance agreements. Does it now mean owning a diesel vehicle can cost the UK motorist more in the long run than petrol ran cars?

Diesel vehicles tend to cost more to buy than the equivalent petrol car, but the benefits of owning a diesel normally out weighed the additional costs.

Since the change in tariffs, diesel owners now pay more in road tax than petrolowners, meaning the only savings they get come from the fuel economy.

Diesel cars are in the limelight for the emissions they give off, but tests reveal that some diesel cars actually give off less NOx than petrol vehicles.

New MOT rules state that if there is smoke coming from a diesel vehicle that has a Diesel Particulate Filter (DPF), or if the DPF has been tampered with it will automatically fail its MOT.

Replacing DPF filters on Diesel vehicles can be costly and generally aren't covered under the manufacturer's warranty.

Is diesel dirtier than petrol?

Typically, yes. Diesel cars, on average, produce a lot more NOx than petrol cars.NOx (oxides of nitrogen), is comprised of NO (Nitrogen Oxide) and NO2 (Nitrogen Dioxide).

NOx is harmful and has been linked to tens of thousands of premature deaths around the world.It comes out of all cars with a combustion engine (so diesel, petrol and hybrid cars).

In latest tests, despite diesel becoming generally cleaner in recent years, diesel engines stillproduce an average of 11.5 times the amount of NOx compared with petrol cars.However, in recent tests they have found a diesel car that actually produces less NOx than theaverage petrol car.

Will Diesel Vehicles Be Removed Altogether?

Not only will diesel vehicles be removed from sale, but petrol engines are set to be banned by2040, this was introduced as part of the UK Governments Air Quality Plan.

There will still be the sale of hybrid and fully electric vehicles after 2040.

The plans set out by the UK Government require local councils to make changes to reduce theamount of emissions in their local area.

  • Encouraging the purchase of fully electric vehicles
  • Changes to road layouts to reduce congestion and higher air pollution points
  • Encouraging more people to use public transport
  • Using lower emission public transport

If local councils can’t make these changes to reduce emissions than restrictions will comes intoplace, for example charging zones, stopping vehicles using certain roads at certain times.

A number of cities in the UK and the rest of the world have committed to removing dieselvehicles from them by 2025.
