Switched Fuels In Your Vehicle?

petrol in a diesel car engine
Switched Fuels In Your Vehicle? Did you fill up petrol in a diesel car & drove it! This mixing up can happen to petrol car owners too. Do you know what it does to your car engine?

Have you ever been unlucky enough to have your car filled in with the wrong fuel by a careless attendant? Were you careless enough to do get your diesel tank loaded with petrol in full volume?

Or are you simply curious as to what happens if you put diesel into a petrol car? Well, read on to find out what really happens and maybe if you’re lucky, you’ll have a chance to undo your crimes.

Diesel In A Petrol Engine

With so many people switching to petrol cars as of late, it might so have happened that one petrol pump worker, while absent-mindedly talking on the phone, put diesel in petrol car by mistake. Well, undoing what’s done is a hard task, but all’s not lost.

What Happens In The Engine

First up, it should be understood that petrol and diesel are different kinds of fuel, with two different types of engines circling it. In engineering jargon, these are classified as SI (spark ignition) and CI (compression ignition) engines. For the sake of brevity, we’ll not delve deeper into what’s what but roughly, SI engines are to be paired with petrol and CI for diesel.

When diesel is poured into a petrol engine, well, nothing happens. Diesel is a fuel too thick even to start burning in an SI (spark ignition) engine. The only thing exploding will be your brain because of your anger. However, things are not so safe the other way around.

Repairing The Damage

If you’d happened to catch that frustration monger while in action, take it easy. If your tank contains less than two litres of diesel, simply top the rest up with petrol. Your car should run fine, though the mileage might take a beating. The worst thing that can happen is minor damage to your engine.

More than two litres and the whole process gets extremely infuriating. But all’s not lost. There are companies dedicated to such cases where people put diesel in petrol car by mistake.

Now, if you’ve mistakenly started the engine, or realised that the engine’s been running on diesel for quite a while now, stop immediately. Just because diesel isn’t combustible in petrol engine doesn’t mean you are out of danger. Diesel is still a highly flammable liquid, capable of bursting into flames any second.

Knowing When You’re On Diesel

If you were oblivious to the fact that you had diesel in your tank, these signs would tell you whether you’re on diesel/a diesel-petrol mixture in your tank.

  • The engine doesn’t start at all. This happens when your tank is filled with diesel for more than half of it.
  • Your exhaust pipe exudes thick black smoke. Your car is mostly running on a petrol-diesel mixture, which is extremely detrimental to your engine.
  • Engine starts misfiring. This happens while trying to start your car with the wrong fuel in it. Loud knocking sound is an indicator that your engine is misfiring.

 

Petrol In A Diesel Engine

A thousand times worse than having diesel in your petrol car is doing it the other way around. Let me give it to you plain and straight – having petrol in a diesel engine as the majority of your fuel will cause an explosion.

Petrol is a lighter in nature and is readily combustible; small amounts of heat generated in a CI engine will simply ignite the fuel. The explosion produced is big enough to dismantle your engine, or simply blow up your whole car to bits.

The incompatibility of engines does not matter here. The intrinsic nature of a CI engine is to have heat omnipresent within the engine; heat from one drive will be a component in the combustion process of the next drive. This is why older cars take some time to heat the engine up before taking off.

Once in contact with the slightest amount of heat, petrol goes berserk, so make sure you keep your eyes wide open to prevent disasters of such explosive nature.

Repairing The Damage

I cannot stress this point enough-DO NOT START YOUR CAR AT ANY COST.

Just in case the magnitude of your mistake wasn’t so colossal, your car might run. A running car is no assurance that your car won’t explode into pieces later on. If you’re already driving, stop immediately.

Now, if you’re of restless and a dare devilish nature, a small amount of petrol in a diesel car might just be offset with topping it up with diesel, though again, we’re not promising you won’t lose your car. We certainly recommend decontamination for even the slightest levels of petrol in your engine.

When the quantity of petrol is noticeably high, that is, more than five litres of petrol, even God’s grace won’t help you in your will drive it. Manually push your car to the side and wait for the fuel recovery companies to take over.

Knowing When You’re On Petrol

If you’ve ever filled petrol in a diesel car by mistake and drove it, chances are you’re already dead. In the off-chance that you’re alive, these on-the-road tips might be useful.

  • When there’s petrol in your engine, your vehicle will become considerably difficult to start. Make sure to take extra precautions so that you don’t attribute this failure to start to something else.
  • A car running on fuel with petrol in a conspicuous quantity will deliver thick black smoke through the exhaust pipe. This is because your car is running on a mixture of diesel and petrol, with diesel in the majority. This is not just bad for your engine; it might ruin It to the point of no return.
  • Engine starts making loud noises under load. If you’re a diesel vehicle owner, treat these three signs with the highest amount of cautionary actions they deserve. Your life is too important to let lethargy make you ignore/delay in reacting to these threats.

Resale Value of Diesel And Petrol Cars In India

Resale Value Of Diesel Vs Petrol Cars In India
Resale Value Of Diesel and Petrol Cars In India

 Apart from few critical factors, there are some points which should be taken care of while buying a car. After all, it’s a big investment for a middle-class family in a country like ours and the more they know about it, the better the choice would be.

Choosing a car model itself is a big dilemma, and then there comes even a bigger question of Diesel vs Petrol car variants of the same model of the car. Pheww! There is a lot of stuff to read and analyze, where experts talk about the cost of both Petrol and Diesel variants of the same model, their mileage difference, their maintenance issues, cost of both types of fuel and a lot more.

Resale Value of Diesel vs Petrol Cars

People tend to opt for the diesel versions of cars as the resale value of these are on an average about 10 % more than the same model Petrol car. This proves to be a substantial argument in the favour of buying Diesel version models of cars.

But what if after a few years, the difference in the resale price could not be more than fifty thousand bucks. The driving comfort of the few years a customer can have with the petrol version of the car is good enough to make up for this loss in resale value.

Also, it should be considered that with the dropping oil prices and our government not aiding fuel subsidies, the gap between petrol and diesel prices in India are going to fade away very soon. In many developed countries, diesel costs more than petrol.

Power of a Petrol Car vs. that of a Diesel Car

For a common man in India, the real test of a car’s power is directly proportional to the people-carrying capacity of a car.

Mostly, petrol cars are considered to have good initial pick-up which is only termed as the better response. As soon as you press the accelerator pedal, the car rushes ahead, but it doesn’t extend the pulling power after certain revolutions. This provides better horsepower, but it also results in a lower torque.

Contrastingly, a diesel car is fitted with a turbocharger. It has a larger amount of pulling power which is because of its elevated torque causing high energy push. But this happens when you pass certain revolutions on the tachometer. This means, there is a large quantity of initial lag (generally known as turbo lag) that occurs. It means despite pressing the accelerator to its maximum capacity, the car will take the time to respond. This produces more torque and lesser power.

Ultimately it all boils down to your choice and demand. If you are more of an enthusiast and expect a fast response from your car, then a petrol car makes more sense. Otherwise, if the thrust of sudden power sends chills down your spine, despite the initial lag, then a diesel car would please you.

 

Environment Cannot Be Ignored

Environment Cannot Be Ignored

When we are talking about Petrol vs. Diesel versions of cars and everything is taken into consideration, how can the pollution caused by them go unnoticed?

  • Kerosene
  • Diesel
  • Petrol
  • Jet fuel

In the above-mentioned order, the crude oil has reached most refined stage. Diesel as a fuel is not as refined as petrol and hence is cheaper than petrol. The less the refinement of the fuel the more it will pollute. Hence it is said that diesel engines are more polluting than petrol engines.

Petrol engines these days have catalytic converters (cat con) that convert pollutants such as CO to lesser detrimental CO2. When compared to petrol cars without cat cons, they have the much lower emission of contaminants.

Diesel exhausts are also considered deadly because they contain higher NOx concentrations and other fine particles known as soot which is not there in general with petrol engines. These are more toxic to humans as they can enter the human body and affect them directly by getting deposited in the lungs, mouth, etc.

Although this doesn’t mean, petrol engines are just more saint. Lack of fine particles and the use of exhaust reduction widely in use since many years have made the perception that diesel engines are the devil which is not the case with the new modern fuel efficient and less polluting engines which are almost at par with their petrol counterparts.

Engine Life of Diesel vs Petrol Cars

One of the biggest debates when it comes to Petrol vs. Diesel cars is the engine life. Believing the experts, diesel engines have shorter life spans because they work on compression type ignition system which has higher compression ratio as compared to petrol engines. If we go ahead with the recommendations of automobile engineers, a well-serviced diesel car can run up to 300,000 kilometres. Trucks, buses, and minivans run thousands of kilometres every day demonstrating the longer life span of diesel vehicles.

Pros of Diesel Car
  • Diesel engines are more efficient as they consume 15−20% lesser fuel. These cars have a slightly higher resale value. The cost of diesel as a fuel is lower as compared to petrol.
  • Lesser polluted environment owing to lower CO2 emissions.
  • Diesel cars offer more low-speed torque, so they have better overtaking power and towing ability.
Cons of Diesel Car
  • Diesel cars usually cost more than their petrol counterparts.
  • Despite its lower CO2 emissions, diesel fuel produces tiny particles that can cause diseases like asthma.
  • Diesel engines are slightly noisier, but this is not the case with newer versions.
Pros of Petrol Car
  • Petrol cars are slightly cheaper to buy.
  • Petrol engines make lesser noise as they are more refined.
Cons of Petrol Car
  • Petrol cars depreciate more because their engines are less competent and consume more fuel than diesel versions.
  • Petrol engines pollute more than diesel cars.

Both diesel and petrol engines are equally popular in the market as both of them have their set of advantages. Ultimately, what all matters is the buyer’s expectations and preferences which reflect in his decision. Anyhow, this enigma of Petrol vs. Diesel cars doesn’t seem to end in near future.

Petrol Vs Diesel: Every Car Buyer’s Dilemma

Petrol Vs Diesel: Every Car Buyer’s Dilemma

Petrol cars are no longer the only available variant in the personal buyer segment. And diesel run cars are also no longer relegated to the taxi segment only. People are giving both fuels equal consideration before choosing a car to their liking. Let us look more into this Petrol Vs Diesel debate!

The Car Pool of Choices :

Except for a few in the small car segment like Eon,  Alto, Kwid etc., all the other cars come in two fuel engine variants; petrol and diesel.

Diesel engines are now customized to fit in with the car they will be running. They are available in different types and can accommodate divergent fuel capacity. Their competitive pricing and other redeemed factors are encroaching on the petrol run ground!

Petrol Vs Diesel Engine :

The major negative up till now with diesel engines were its high Noise Vibration and Harshness (NVH) levels.

With refinement in the engine run by diesel by the car manufacturers, that clatter has gone down considerably. The sound is only a minimal on the outside and comparable to a petrol model on the inside. That too is smoothened out by the manufacturers in the more high-end models.

Several sites measure and display the car’s NVH levels. You should look into those and your personal bias towards vibrations and noise before making a decision to buy a particular make, model, and its variant. Although, the life of a diesel engine is comparatively shorter than its petrol version.

Comparing Performance of Petrol Vs Diesel :

Horsepower is another critical component to be considered when deciding on which car to purchase.

In several countries, the power is determined by the number of people a car can comfortably carry! But there is more science to it than that!!

A low to medium range, affordable petrol cars, clearly display the singular power of its engine. It means the car responds well during the first pick-up.Accelerating on lower gears makes the car rush ahead but not with much power beyond certain Revolutions Per Minute or RPM. This makes the engine great in terms of Horsepower or PS but it loses on Nm or Torque.

Diesel run engines; on the other hand, have turbochargers, which increases the car’s Horsepower (PS) considerably. The Torque (Nm) shows impressive figures too. All these can be achieved only after the engine’s tachometer leaps beyond particular RPMS.

The frustration comes in at the beginning because the vehicle will face a turbo or initial delay. Even flooring the pedal won’t make the car respond to your command to gain power and speed up! This leads to an increased Nm and low PS. Car’s response time and your thirst for power should tell you which engine you will choose between petrol and diesel.

Competing Mileage by Petrol Vs Diesel Car :

There are no two ways about the fact that a diesel car outshines a petrol car in terms of mileage.

Diesel engines don’t require spark plugs and therefore, can provide a much higher comparable compression. This makes the diesel engines more fuel efficient in terms of usage. Long-term fuel efficiency offsets the higher on-road purchasing cost of the car.

Petrol Vs Diesel Pricing :

The cost of diesel is less than petrol, an exception being Goa. Because of limited deregulation of the diesel prices in the year 2013, the price difference between the two fuels is noticeable and is going to continue to be so.When calculated in terms of savings in comparison with each other, diesel wins hands down.

Diesel costs less, and its engine uses it efficiently. Hence, there is a considerable time gap between each tank fillings! All these can be monetized for a better understanding!

An Example:

Let us understand all the concepts by taking a live example of a Maruti Swift.

On-road cost of a Maruti Swift VXi: Rs.603936/-

On-road cost of a Maruti Swift VDi: Rs.740329/-

The price difference between the two is Rs.136393/-

Current cost of petrol in Delhi: Rs.61.14 per liter.

Therefore, approximately 2,231 liters of petrol can be filled with the price difference between the two variants.

Suppose the average mileage given by the car is 15 Km/l, the car can be driven for 33,465 Km.If you cover an average distance of 55-65 Kilometers every day, that means it will take you approximately 558 days to cover the total distance and utilize the entire petrol!

In conclusion, a petrol version of Maruti Swift will run for one and a half years more for the extra amount you paid for your diesel variant!

The length of the daily run should decide the purchase of the fuel variant. Petrol run cars are ideal if the everyday commute is not much. Otherwise, opt for diesel cars.

Car Maintenance and Servicing :

Buying a car is a one-time thing, but its service and maintenance are a lifelong expenditure.

On comparison, over a similar period of time, service cost per km, as well as the cost of parts that need servicing, is quite expensive for a diesel engine.Changing parts due to wear and tear or damage, and other repairs are extra. Spare parts for a diesel engine cost more than its petrol counterpart.

Resale Value of Petrol and Diesel Variants :

Diesel cars resell at 10% above the market resale value of its petrol variant. The percentage difference comes down to the age of the cars increase.

Also, with the new regulations regarding the age of diesel run cars being road worthy, changes in oil pricing, alterations in fuel subsidies, pollution level, and more, diesel cars do seem less worthy.Also, diesel costs more than petrol in a lot of countries.

The Choices We Make : Petrol Vs Diesel

Ultimately the choice rests on the need and requirements of an individual. What he wants from his car is the eventual deciding factor.

You can compare the on-road cost of the variants, the mileage, the power, the cost of maintaining the car, fuel charges, the noise levels and be abreast with all the latest regulations in the fuel pricing and transportation. Only then make an informed decision!

Petrol Vs Diesel Cars in India 2016 – Which is better?

Petrol Vs Diesel Cars in India 2016 – Which is better?

Cars have become a common itinerary in the wish-list of the middle class population of today’s cities. But it is a common problem with the general mass on choosing between the petrol and diesel variants of a car. Getting opinions of the near and dear ones might seem confusing rather than enlightening, and so here is a guide to choosing your dream vehicle.

Before giving the titbits, there are certain considerations that have been taken into account.

  1. The inferences have been arrived at by considering the pocket of a normal middle class person in India, who plans to buy a car.
  2. The car models have been decided by the prevalence in Chennai city and its suburbs.
  3. The numeric values are based on the current trends in the Indian market (that is, considering May 2016)
Petrol Vs Diesel Cars in India 2016 – Which is best?
Petrol Vs Diesel Cars in India 2016 – Which is best?
Price of the car:

This would vary depending upon the buying capacity of the consumer. But for Chennai, or in general, India’s traffic, a 4-seater hatchback in the bracket of 5 to 7.5 lakhs would be the affordable choice for everyone. Moreover, the cost difference between the petrol and diesel variants which is about 60,000 to 1 lakh INR for the cars below 8 lakh levels tend to increase as we increase it beyond 10 lakhs. For ultra-modern, savvy cars that cost around 25 lakhs, the price difference is generally around 1.7 lakhs to 2.5 lakhs.

Diesel variants usually cost more than the petrol ones because of the former’s enhanced efficiency aspects.

Distance traveled per day:

The daily sojourn comes into consideration here along with a few other extra trips that one would make periodically in his/her car. The routine travails imply the distance covered by an office-goer from home, from the taxi depot to the designated stand in case of a taxi, etc. The other trips include weekend visits to picnic spots and unexpected emergency situations.

Cost of petrol vs diesel per litre :

Before the government deregularization came into existence, the price of diesel used to be as much as 16 to 20 rupees lesser than that of petrol in the subcontinent. But now, the margin has come down to a maximum of 13 to 15 bucks. This is one important aspect that needs to be considered along with the general price bracket of the car.

Mileage of the car:

The ideal mileage specified would have certain condition attached to them.The mileage specified cannot be achieved at any point during city drives, where intense traffic is the common scenario throughout the day. Mileage would also depend on the quantity of load that the car needs to carry other than the kerb weight (the weight of the car with no load) and the other external factors like optimum usage, smooth driving and efficient, serviced components. Increase your car mileage by following these 8 simple tips.

Petrol vs Diesel Cars In India Case study:

Since an aam aadmi would opt for the price range between 5 lakh and 7.5 lakh INR, let us assume 6 lakhs to be the cost of a car X. Considering Chennai city, a person would normally travel around 40 kilometres on an average (the to and from distance between Adyar and Tambaram, approximately) to his workplace and back.

(All the quantities detailed below are arrived after considering most of the cars in the price range, and they may not be exactly specific or accurate, as they do not point out to any particular brand or model)

Cost of petrol = INR 62 per litre

Cost of diesel = INR 53 per litre

Mileage of the petrol variant = 20 kmpl

Mileage of the diesel variant = 24 kmpl

This would mean that for a person travelling 40 kilometers daily, 2 liters of petrol or 1.7 liters of diesel are required.

Cost for petrol per day = 62 * 2 = INR 124

Cost of diesel per day = 53 * 1.7 = INR 90

This would mean that the daily savings by driving a diesel vehicle is around 35 bucks for the above mentioned case.

Now let us take into account that this person has to travel to his workplace for 25 days in a month, 35 * 25 = 875 bucks a month.

(Note that no extra travel is taken into account in this case)

If there are going to be some other travels as discussed at the beginning, let us take this as around 200 kilometers for a month. So if 35 bucks is the savings for 40 kilometers, it is 175 rupees for 200 kms.

So overall price saving due to diesel vehicle = 875 + 175 = INR 1,050 per month

For a year, this is 1,050 *12 = INR 12,600

Now consider the extra buck you have to pay when you are buying the diesel variant, say INR 80,000.

Payback period = 80000/12600 = 6.35 years

Petrol Vs Diesel Car Payback EMI in India
Petrol Vs Diesel Car Payback EMI

This would approximately mean 6 years and 4 months. If the car is purchased in loans or EMIs, the interest amounts need to be added up which would add a year more. So for a common man (who would buy the car only through installments or loans), it would around 7 ½ years to repay the initial costs, provided the above mentioned conditions are satisfied.

This would get reduced if the person travels around 60 to 70 kilometers per day in the diesel variant (the payback period would come down by almost two years). But there are other factors that are needed to be addressed in petrol and diesel cars .

The NVH (noise, vibration and harshness) is more in diesel vehicles than that of petrol generally. And hence the maintenance cost is high for the diesel car owners. So for long-term benefits (say 7 to 10 years), diesel vehicles can be deemed fit. But if you are looking at it in the point of view of around 3 to 5 years, petrol variant would sound a good choice.
