The answer depends on the number and type of miles you cover. Drivers who cover most of their miles with multiple short journeys around towns should choose petrol rather than diesel. If you do lots of longer journeys or motorway miles a diesel may be a better option.
- Should I choose a petrol or diesel car?
- Deciding between petrol or diesel power has been a dilemma for drivers for many years. Each has its pros and cons – such as suitability for short journeys and overall running costs. Still, the diesel engine has come under increased scrutiny over more recent years, mainly due to its impact on the environment.
- Is it still worth buying a diesel car?
- Even so, the reality is that many economies will still rely on fossil fuels for many years, decades even, to come. Our view is that many drivers, especially those doing long-distance trips and motorway miles (say 20,000+ miles a year), will likely still be financially better off picking a diesel car, on account of its better mpg.
- What are the pros and cons of diesel cars?
- Here are their main pros and cons: Being great for long journeys. If you’re in for long car trips, choose diesel over petrol engines since they provide more power at lower engine revs. Featuring better fuel economy. Diesel cars give their owners better mpg than their petrol counterparts due to their fuel containing more energy per litre.
- Do diesel engines still have a place?
- If, however, you cover lots of motorway miles a year, diesel still has its place, thanks to plentiful opportunities to refuel and the car’s ability to return plenty of miles per gallon. Among the reasons for the continuing popularity of diesel engines is that they typically emit less carbon dioxide (CO2) than a petrol engine of equivalent power.

What is the future of diesel cars?
But the end is in sight, as the government has declared that sales of petrol and diesel cars will end in 2030. Some car industry observers think this is ambitious, but either way, in a few years years, there won’t be many diesel cars on sale. They will survive beyond that, but by 2050 they could well be a rarity.
- What is the future of diesel cars in the UK?
- The UK government plans to introduce “zero emissions” for new passenger cars by 2040. The initiative could include a more ambitious plan to ban the sale of new cars with petrol and diesel engines by 2035. Although the proposed changes are still a few years away, the short-term future of diesel cars seems vague.
- Is diesel still a good option?
- Diesel might be demonised, but it can still be a good option – see when’s best to buy a diesel car and what the future holds. The war against diesel drivers can seem relentless. After tax increases and parking surcharges and the announcement of a future sales ban, come low emission zones.
- Can you buy a diesel car in 2025?
- Future legislation in Europe will impose ever-tougher emissions controls on cars that do burn fuel. So you can expect future Euro 7 laws from 2025 to clamp down on pollutants even further, meaning you can in fact buy a modern diesel car with confidence for some years to come. Just be mindful the direction of travel is very much against diesel.
- Should you buy a non-diesel car?
- Many are doing just that: new diesel car sales were down by a quarter last year, and a recent BuyaCar survey found that three in five diesel drivers planned to change their car for a petrol, hybrid or electric model. But while many are better off buying a non-diesel car, diesel engines still have a place.
Do diesel cars require daily running?
Need to be driven daily, else maintenance becomes high This is by far the most common misconception. Modern diesel cars do not need constant attention. You can use it when you need to. Else you can park it safely without worrying about the parts becoming jammed.
- Do modern day diesel engines need daily running?
- No, modern day diesel engined do not need any minimal daily running. I know many who use the car once a week or lesser. However, a low running diesel engine is not recommended as you may not be able to use the higher fuel efficiency of a diesel engine to cover up the extra initial cost of the vehicle.
- Should I Keep my diesel engine at high RPMs?
- Diesel cars also have a lot of torque, so there will be no need to keep the car at high RPMs. Don’t keep them too low for too long, either. Diesel cars produce soot caught by the DPF and revving the engine once in a while helps get rid of the accumulated soot.
- Is it harder to run a diesel car on a short trip?
- Lots of short trips are harder on engines and vehicles then longer ones where they can warm up to operating temperatures. Water condenses in the internal parts of What happens when a diesel car is not run for two months?
- How often do you need to run your engine?
- In general engines let it be petrol, diesel or any other ones have to be run regularly as they are machines. Machines are meant to be used, to be run and get work out of them. I find it surprising that people buy a car and after 10yrs have done only 20–30000 kms, for that matter even 50000kms for a 10yr car is very less.
What are the disadvantages of petrol cars?
Petrol is expensive when compared to diesel and adds to the running cost of the car over the years. Also, because of the volatility of petrol, mileage of the car also suffers. Petrol engines tend to clog up quickly and require maintenance more frequently.
- What are the disadvantages of a petrol engine?
- Also, because of the volatility of petrol, mileage of the car also suffers. Petrol engines tend to clog up quickly and require maintenance more frequently. If not serviced regularly, petrol engines can deteriorate faster than their diesel counterparts.
- What are the disadvantages of a diesel car?
- Diesel cars depreciate at a slower rate. Diesel cars tend to be more expensive to buy than similar petrol models. Diesel fuel usually costs more. Servicing can be more expensive, although you don’t need to do it as often. Insurance can be 10-15% higher. Diesel cars produce a lot more NO2. Tiny particles in diesel can cause asthma flareups.
- Can a diesel nozzle damage a petrol engine?
- It will cause the car to stop running and require flushing out the fuel system, but it won’t damage the engine. However AFAIK the diesel nozzle shouldn’t fit into the fuel opening for a petrol car. Gasoline in a diesel engine can cause engine damage. Diesels aren’t meant to, but will run (for a little while at least) on gasoline.
- Do petrol cars pollute the air?
- Conventional petrol cars run on fuel and pollute air. There are five main harmful pollutants caused by conventional petrol cars that contribute to air pollution, which are carbon dioxide, sulphur dioxide, mono-nitrogen oxide, fine particles, and volatile organic compounds (Holland et al., 2015, 11).
Why is petrol cheaper than diesel?
Why is diesel more expensive than petrol? Although diesel and petrol are taxed the same by the Treasury, historically diesel has been more expensive than petrol, as domestic refineries have struggled to meet demand. This has forced the UK to import diesel from other countries at a greater rate than petrol.
- Which is better petrol or diesel?
- Petrol cars are usually cheaper to buy and you’ll pay less at the pumps for a litre of unleaded. Diesel offers better fuel economy (typically 15-20mpg on a family car) and lower car tax. Which one costs less overall depends primarily on how long you plan to keep the car. Take the Ford Focus again.
- Are petrol cars cheaper to buy?
- Verdict: petrol cars are cheaper to buy. The average price of petrol in the UK is almost £1.30 a litre, or around £1.36 for diesel. Although diesel is more expensive to buy at the pumps, it is still the more economical option in terms of miles per gallon – in other words, it uses less fuel per mile.
- Are diesel cars cheaper in the long run?
- Verdict: diesel cars are cheaper in the long run Running costs: Road tax for diesel cars is usually lower, and diesel cars also tend to have a better resale value than petrol cars.
- Is car insurance more expensive for a diesel car?
- Generally, car insurance is slightly more expensive for a diesel car, simply because they are more expensive vehicles to start with. Maintenance costs throughout the life of the car are pretty similar for both petrol and diesel cars, though petrol cars need fewer oil changes.
Are diesel cars better or worse?
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.
- Is a diesel engine better than a petrol engine?
- Because diesel engines offer better fuel economy they can be considered to be better for the environment. The emissions they produce are dirtier than a petrol engine, but because you can get more miles for the equivalent volume of emissions they can be considered more environmentally friendly. They perform better.
- Is diesel fuel bad for your car?
- It’s important to remember that some types of diesel fuel can have a negative impact on vehicle performance. These include black diesel, biodiesel, and other enhanced diesel products. For most U.S. consumers, diesel fuel and gas fuel cost about the same. Sometimes diesel rises above gas in price and other times drops below the cost of gas.
- Is diesel a more environmentally friendly fuel?
- Diesel was promoted as a more environmentally friendly fuel as part of the EU’s response to the 1997 Kyoto Protocol to reduce greenhouse gas emissions, especially carbon dioxide (CO₂). Diesel engines are “lean-burn”, meaning they use less fuel and more air to get the same performance as a petrol engine.
- Is a diesel car louder than a petrol car?
- Noise: while diesel cars have become much more refined over the years, they’re still noisier than an equivalent petrol car ( sports cars aside). Often described as a ‘clatter’, the sound produced by a diesel car tends to be less pleasing to the ear than that made by a petrol engine.
Is it bad to drive a diesel short distances?
Diesel Rule 3: Don’t buy diesels for low mileage or inner city life. Also known as “diesel car city driving”, you want to avoid doing this. It’s well known by petrolheads, but always worth explaining why. Driving at low speeds and short distances clogs up your Diesel Particulate Filter (DPF) quickly.
- Can I drive a diesel car on a short journey?
- Yes, short journeys will inevitably cause issues as diesel cars aren’t intended for this kind of use. Diesel engines produce a lot of soot – also called particulate matter (PM) – when they burn fuel. The job of the DPF is to filter and store this soot – which can cause harmful health issues – in order to reduce emissions from diesel cars.
- Should you buy a diesel car with high mileage?
- Diesel Rule 1: NEVER buy high mileage. To be clear – avoid diesel cars with over 100,000 miles on the clock. Just avoid them. Really. They will cost you money, time and hassle. Of course there are exceptions to every rule, but it isn’t worth taking a chance with these vehicles.
- Are restricted driving ranges bad for diesel cars?
- Restricted driving ranges can create expensive problems for owners of diesel cars, if they’re not careful. Owning a diesel car can have its upsides but diesel cars are not designed for low mileage driving. They are at their most efficient on long journeys and have particular problems when being driven on short journeys at low speeds.
- What is worse than short trips in a diesel?
- There’s one thing worse than short trips in a diesel that do not let it get up to operating temperature, and that is; short and slow drives. We have already covered exactly the risk you run when you make short drives but what happens if you drive a diesel slow and never get up to speed and don’t have a chance to get the RPM’s up?
Do diesels need long runs?
The long and short of the issue is, you must regularly run a diesel engine at high speeds for between 30 and 50 minutes to allow the exhaust temperature to increase enough to cleanly ‘burn off’ the excess soot in the filter and clear it – motorway driving is ideal for this.
- How long does a diesel engine last?
- Your car’s gasoline engine should last roughly 200,000 miles before it requires a major maintenance or you need to purchase a new vehicle. But diesel engines can constantly run for an amazing 1,000,000-1,500,000 miles before needing any substantial work. In fact, a well-maintained diesel engine can last for 30 years or more on the road.
- Do diesel cars need daily running?
- CRDI is Common Rail Direct Injection. This allows direct injection of fuel into the enginethrough a single common line. This is why there is no need to run your diesel car regularly these days. Now no one will ask do diesel cars require daily running or not.
- Why does a diesel engine need less fuel?
- In a gasoline engine that’s not working at full power, you need to supply more fuel (or less air) to the cylinder to keep it working; diesel engines don’t have that problem so they need less fuel when they’re working at lower power.
- Do I need to warm up before running a diesel engine?
- Yes. Most manufacturers recommend idles for 3 minutes before running the engine under a load. Always look at your operator’s manual to see the exact specification for your engine. This is a common misconception. Modern diesel engines do not require the amount of time to warm up as in years past.
How long will petrol cars be around?
The petrol and diesel car ban only affects sales of new vehicles, so yes, you’ll still be able to buy and sell used cars that are powered by combustion engines after 2030, and you’ll also be able to buy and sell used hybrids after 2035.
- How long will a petrol or diesel car last?
- As the average life of a car is 14 years, new petrol and diesel cars bought in late 2029 could remain on the roads until 2044 at least. 7. What will happen to classic cars when petrol is banned? At the moment there is no suggestion that classic cars powered by traditional petrol or diesel engines will be forced off the road.
- What will happen to petrol cars in 2030?
- Increasing take-up of electric cars means more used combustion engine cars around and simple economics dictates that petrol car values will fall. And imagine if there’s been a huge hike in sales of petrol and diesel sales in the run up to 2030.
- Can you still buy a petrol or diesel car?
- The petrol and diesel car ban only affects sales of new vehicles, so yes, you’ll still be able to buy and sell used cars that are powered by combustion engines after 2030, and you’ll also be able to buy and sell used hybrids after 2035. 5. What will happen to the value of my petrol or diesel car?
- Is it legal to buy a petrol car in 2029?
- No, the petrol and diesel car ban is only on the sale of new combustion engine cars – those already on the road will still be legal to own and drive. As the average life of a car is 14 years, new petrol and diesel cars bought in late 2029 could remain on the roads until 2044 at least. 7. What will happen to classic cars when petrol is banned?
Is diesel highly flammable?
If you toss a lit match into a puddle of diesel fuel, it’ll go out. That’s because diesel is much less flammable than gasoline. In a car, it takes intense pressure or sustained flame to ignite diesel.
- Is diesel fuel flammable or combustible?
- Therefore, diesel fuels with a flash point below 60 °C are classified as flammable liquids and those that have a flash point above 60°C are classified as combustible liquids. While combustible liquids have similar properties to flammable liquids, they are regarded as less volatile substances because they have a higher flash point.
- What is the flash point of diesel fuel?
- The flash point of diesel fuel is between 72°F and 99°F. The flash point of diesel fuel is the temperature at which it ignites. At this point, diesel is actually flammable and will burn with a visible flame and smoke. However, it will not explode. The flash point is determined by the amount and nature of the hydrocarbon constituents in the fuel.
- Does diesel catch on fire?
- While diesel does catch on fire, it is not as quick as compared to other types of fuels like gasoline. That is because diesel has a higher flash point than gasoline, and it could only be ignited when this flash point is reached. Is diesel a combustible substance?
- What is diesel fuel?
- Diesel fuel. Diesel fuel, also called diesel oil, combustible liquid used as fuel for diesel engines, ordinarily obtained from fractions of crude oil that are less volatile than the fractions used in gasoline. In diesel engines the fuel is ignited not by a spark, as in gasoline engines, but by the heat of air compressed in the cylinder,…
Is electric car better than petrol?
Electric vehicles are more efficient, and that combined with the electricity cost means that charging an electric vehicle is cheaper than filling petrol or diesel for your travel requirements. Using renewable energy sources can make the use of electric vehicles more eco-friendly.
- Is it cheaper to run an electric car than a petrol car?
- To many, the decision comes down to the simple matter of cost. An electric car is cheaper to run, and servicing and maintenance costs tend to be lower than for petrol cars. But does this outweigh the higher initial pricing of EVs?
- Why are electric cars better for the environment?
- There are two main reasons why electric cars are so much better for the environment than petrol and diesel. 1. Electricity is getting cleaner all the time While conventional cars will always need dirty fossil fuels, electric vehicles can (and increasingly do) run on renewable energy.
- Are electric cars cleaner than gas cars?
- Yes: although electric cars’ batteries make them more carbon-intensive to manufacture than gas cars, they more than make up for it by driving much cleaner under nearly any conditions. Although many fully electric vehicles (EVs) carry “zero emissions” badges, this claim is not quite true.
- Which is better petrol or EV?
- From their effortless power delivery to the option of driving in ULEZ zones for free, you also get the best range out of an EV in these stop/start driving conditions. If you regularly travel long distances and visit areas where the EV charging infrastructure is patchy, then a petrol car will be the better bet.
How many miles should a diesel car do a year?
As such, the average annual mileage for a diesel car is normally around 9,000 to 10,000 miles. A higher mileage car might have travelled on average 15,000 miles per year, with many covering well 20,000 miles per year.
- How many miles can a diesel engine run?
- According to Prosource Diesel, a secondhand diesel truck with a Cummins or Duramax engine with more than 350,000 kilometers is considered excessive mileage. For a Powerstroke diesel engine, anything above 350,000 miles is considered high mileage. How often do diesel cars need a good run?
- Is a diesel car right for You?
- The UK is falling out of love with diesel for various reasons. But a diesel car could be right for you if your annual mileage is around 15,000+ miles per year. This is because diesel is around 20% more efficient than petrol so it should be cheaper to run in the long term, but only for drivers who go long distances or travel on motorways regularly.
- Should you buy a diesel car with 100,000 miles on the clock?
- To be clear – avoid diesel cars with over 100,000 miles on the clock. Just avoid them. Really. They will cost you money, time and hassle. Of course there are exceptions to every rule, but it isn’t worth taking a chance with these vehicles. If you must buy a high-mileage car, buy the petrol model with the largest engine. Why?
