Whether to purchase diesel or petrol car, is an old debatable question that doesn’t have a simple answer. So, if you want to reach a specific decision of buying a petrol Vs diesel car, consider taking into account the following factors.

Petrol vs Diesel – Which is the Best?

Before delving deeper into the explanation of the diesel and petrol engine, it’s important to know, from where it all started.

Getting to know the petrol engines, they were the first to be used in the automobiles. While the diesel engines were mainly used for commercial purposes like in trucks, ships, or buses. Fundamentally, not much has changed with the use of petrol engines but the same cannot be said for diesel engines. As, they have proved their worth in the cars, as well.

So, now if you’re ready to know about the factors determining the better engine, let’s get started!

1. Which Type of Engine is More Efficient-Petrol Vs Diesel?

In order to find the better engine out of petrol Vs diesel, in terms of efficiency let’s consider the following aspects, first.

Fuel Burning

A standard diesel fuel has approximately 38.8 Mega Joules of Energy/litre while the petrol yields 34.8 Mega Joules of energy/litre. This means, for producing an adequate amount of energy to run a car, diesel burns much slower than the petrol. As a result, the mileage of the car increases, if it uses diesel instead of petrol.

Compression Ratio

Firstly, here it’s important to note that engine’s efficiency is directly proportional to its compression ratio.

Compression Ratio ∝Production of Mechanical Energy ∝ Engine’s Efficiency

This means, if the compression ratio is high of a fuel, it can convert a large amount of chemical energy into the mechanical ones.

Thus, when the concept is introduced in petrol and diesel fuel, it has been observed that diesel yields more efficiency and mileage. With the standard compression ratio of 20:1, it produces more mechanical energy than the petrol with 10: 1 or 12: 1(standard).

Torque Value

The diesel engine can develop higher torque value than the petrol one. But, what exactly, is it?

Well, the torque is actually responsible for determining the turning force required to drive away the vehicle. In simple words, when a high value of torque is produced at low RPM, this means you can increase the engine speed without wasting much of the fuel.

2. Which Type of Engine is More Powerful-Petrol Vs Diesel?

Here, the petrol engine wins, as it has lighter parts than the diesel engine. That further allows for the high Revs, when the engine is operated.

Thus, it results in the more performance efficient engine in terms of petrol than the diesel.

3. Which Type of Engine is More Recommended?

Other than, all the above-defined factors, when the diesel and petrol engines are compared based on the cost of fuel, car, and maintenance, the story is somewhat different.

We all are aware that the price of diesel fuel is far less than that of petrol. This is indirectly related to the prices of the car. In other words, diesel cars are costlier than the petrol vehicles. Moreover, the maintenance cost of a diesel car is far higher than the one needed for the petrol-vehicle.

So, if most of your work is on motorways or you have to drive a long distance daily, consider purchasing diesel cars. Or, else if your mileage is lower or you drive locally often, go for the petrol cars.

Finally, now when you are aware of the pros and cons of the petrol Vs diesel engine, hope you can select the vehicle that suits your requirements.

Whats your take?

Petral

I prefer diesel because it is non flamable.

However, none of them will soon be preferable as electric cars are taking over.

Gas engine nko

Diesel it is naa.
Highest torque, MPG etc but unfortunately, the diesel sold in Nigeria and most of black Africa is the lowest of the low quality and most adulterated of the adulterated.

Correct @above. But there is this general belief that diesel brings about dirty work environment.

Let me learn something new

Can you define petrol and diesel?

Car na car. Prayer be say make we no die for accident.

Anyone but my car uses petrol

op, you raised a topic petrol vs diesel, which one is more efficient, and in the end you couldn't be able to tell us which one it is.. you just rundown what we know and left us to choose, whereby you are suppose to tell us which one is better.... this is how Nigerians fail exams.

Diesel is better but don't allow your tank to be empty

Not in naija sha..

petrol engine all the way.

...read mr...it depends on what u want...long distance travelling or heavy duty vehicles, diesel are preferable but normal vehicle activities and short travel, then petrol

Not in naija sha..

...who told u...hybrid cars(petrol+electric) are already becoming popular and I see them everyday here in naija

If u live in the Niger Delta don't buy any Diesel engine or u and mechanic will be best of friends thanks to Kpor Fire

We all are aware that the price of diesel fuel is far less than that of petrol.


Is this true?

.

Diesel is stronger but that weird sound

diesels are better if you cover many miles and move heavy items, i noticed its more expensive to run diesel vehicles in the city as fuel consumption is much.

diesel engines are very dirty even when you do oil change its still black and dirty.

lastly the skill of doing a complete engine overhaul is fast becoming lost as the average mechanic prefers you buy another engine.

Is this true?

diesel is more expensive than petrol all over the world, the present fuel scarcity makes petrol seem more ecpensive

Nice write up tho...
But that last question is not necessary the way Nigeria is structured. An average Nigerian believes that car na car in as much u will not be wakaring in the sun again, even kerosene engine. Just like my sister @34 in tosyn2much thesis, husband na husband in as much he can talk.

manual + Auto = ?

It's petrol simple
