process is more efficient, adding up to higher fuel efficiency and lower CO2 emissions when using diesel.

Is it better to have petrol or diesel?

Petrol cars are generally less fuel-efficient than diesels

You might pay less for petrol per litre than diesel, but you could well end up using more of it. That's particularly true on longer drives at higher average speeds, where diesel engines are at their most efficient.

Do diesels last longer than petrol?

So, do diesel or petrol engines last longer? Diesel engines do last longer than petrol ones. Diesel is a light oil and when burned and used as fuel by the vehicle it lubricates the parts of the engine. This prolongs the life of the engine.

Which is more harmful petrol or diesel?

The science now tells us that diesel vehicles cause more than four times the pollution than petrol cars. Diesel cars have recently become subject to considerable negative publicity thanks to the amount of toxic emissions they produce.

Is diesel car worth buying?

Put simply, you should buy a diesel car if you regularly cover a lot of high-speed miles, i.e. a regular motorway commute rather than lots of short trips. Diesel cars give better fuel economy than their petrol counterparts, as well as offering more torque on tap for those who want to tow or the like.

What are the disadvantages of diesel cars?

Why are diesel engines better?

Diesel engines are still more efficient than gas engines, but less so for those who are mostly engaged in city driving. Diesel cars also have more torque, which results in better fuel economy along with more impressive acceleration.

Which engine lasts the longest?

Which car engine has more life?

It's normal for your car's gasoline engine to run for around 200,000 miles before it needs a serious overhaul, or you need a new vehicle. But diesel engines can continuously run for an impressive 1,000,000-1,500,000 miles before needing any major work.

What are the benefits of diesel over petrol?

Diesels are more fuel efficient than petrol engines and emit less CO2, which makes them better for the environment. Diesels produce considerably more torque (pulling power) than their petrol counterparts, which makes them good engines for towing or carrying heavy loads – ie: seven occupants – on a regular basis.

What are the disadvantages of petrol cars?

The main disadvantage, however, of petrol vehicles is that they are not particularly energy efficient and they aren't environmentally friendly. As they are powered by fossil fuels, they use a lot of non-renewable energy sources, which means at some point in the future, the fuel will no longer be available.

Why do diesels last longer?

Diesel fuel is a type of distillate fuel that is essentially produced from crude oil, which gives diesel engines slower cylinder wear than gasoline engines. This gives diesel fuel lubrication properties that extend the overall lifespan of the engine.

Which country makes the best engines?

So who makes the most reliable engines? Perhaps not surprisingly, it's the Japanese, with the top spot taken by Honda. Only one in every 344 Honda owners have had engine trouble, with second-placed rival Toyota notching up just one in 171.

What is the most respected car?

Which burns faster petrol or diesel?

Petrol is produced at lower temperatures while diesel is produced at higher temperatures. As such petrol combusts (burns) faster at lower temperatures while diesel burns at higher temperatures. In car engines petrol is ignited by spark while diesel is ignited by compression.

Are diesel cars faster than petrol?

In very simple terms, higher horsepower translates to a higher top speed and a faster car. Conversely, a higher torque figure translates to more power at a lower RPM. When this is taken into consideration, diesel engines are the more powerful of the two.

What are the pros and cons of diesel cars?

Is it worth buying a petrol car?

The main reasons are around convenience. A petrol car will usually be cheaper to buy than a diesel version. You'll save money at the petrol pump, and it's still easier to find somewhere to refuel than hunting for an electric car charging point.

Are diesel cars going to be banned?

All new conventional petrol and diesel cars and vans are set to be banned from sale in 2030. New hybrids will be given a stay of execution until 2035, on the condition they are capable of covering a "significant distance" in zero-emission mode - a term which the Government has yet to define.

Should I buy a diesel car for short journeys?

If you do lots of short, low-speed trips, then petrol will be a better option. Diesel engines use a particulate filter to help reduce pollution, but this needs faster runs to keep it in top working condition. If you just do short journeys, it will get clogged and harm a diesel car's running.

Are petrol cars good for long drive?

If you want to keep a car for long and drive more than 80-100km a day, diesel can be a valid option. Otherwise, if your running is quite less and you don't prefer keeping a car for more than 3-4 years, go for petrol.
