Here, we will focus on the key difference between petrol cars and diesel cars that will help you decide the correct variant. We will also discuss when one is preferable over another and why.
So, let’s start this test drive and see who wins the petrol vs diesel car race!
What are Petrol and Diesel Cars?
The definition of petrol and diesel cars is easy to understand. Wondering how? Read along!
A vehicle that features a petrol engine (has internal combustion with spark ignition) and runs on petrol is called a petrol car.
On the other hand, diesel cars use internal combustion engines, have a compression-ignited injection system, and run on diesel.
Here are the top 5 cars with both petrol and diesel engine options available in India.

As the basic idea of petrol or diesel cars is clear to you, let’s learn about the differences between these variants.
Difference Between Petrol Cars and Diesel Cars
Follow the table mentioned below to get the answer to your question of ‘which car is best - petrol or diesel’.
|
Basis |
Diesel |
Petrol |
|
Mileage |
Diesel cars provide increased mileage. A diesel engine does not require a spark plug and hence has a higher compression. This enables diesel-powered vehicles to utilise fuel to the maximum level. |
Petrol cars offer less mileage. |
|
Power |
Cars powered by a diesel engine have a longer stroke (requires more compression to burn), allowing it to rev less and put a high amount of torque for an engine of similar size. |
Cars powered by a petrol engine have a shorter stroke, which lets them rev more and place more power. |
|
Car Price |
Diesel variants are a bit expensive. |
Petrol variants are less expensive. The showroom price between diesel and petrol variants ranges from ₹1- ₹1.5 lakh. The difference in the case of on-road prices also increases as the registration cost of a diesel car is higher than that of a petrol car. In general, there is a 1%-3% difference. This depends on the vehicle cost and the state from where the vehicle is purchased. |
|
Cost of Fuel |
The rates vary from one state to another. The diesel rate is ₹85.01 per litre (as of 12th November 2021). |
The petrol rate is ₹100.58 per litre (as of 12th November 2021). |
|
Resale Value |
The price for resale is high. |
The resale price is low. |
|
Car Insurance |
As the cost of diesel cars is high, insurance costs automatically go on a higher side. The difference can range from 10%-15%. |
The amount of car insurance is less for petrol cars as the car price is lower than diesel cars. |
|
Pollution |
Diesel cars produce less carbon dioxide and more pollutant particles, hence causing more harm to the environment. |
Petrol cars generate more carbon dioxide but fewer pollutant particles, hence causing less harm to the environment. |
|
Noise |
Diesel variants produce excessive noises. |
Diesel variants produce less noise. |
If you are wondering ‘which is better between petrol and diesel car?’, the table mentioned above can help you decide the best variant. Furthermore, let’s see different conditions for selecting one fuel engine/type over another and vice versa.
When is a Diesel Car Preferable over a Petrol Car?
If you travel long distances frequently, a diesel car is preferable. If longevity is your priority, a diesel car holds the top position. When choosing a diesel car in India, other factors to consider are:
- High mileage: Diesel engines often provide better fuel efficiency, making them cost-effective for drivers who cover long distances regularly.
- Towing capacity: Diesel engines tend to offer higher torque, making them suitable for towing heavy loads. If you frequently tow trailers or caravans, a diesel car may be a better choice.
- Long-term ownership: If you plan to keep the car for an extended period, the fuel efficiency and potential longevity of diesel engines might make them a more economical choice over time.
- Highway driving: Diesel engines excel in highway driving conditions where their fuel efficiency and torque contribute to a more comfortable and economical driving experience.
- Resale value: In some markets, diesel cars retain better resale value, especially if they are well-maintained and have lower mileage.
When is a Petrol Car Preferable over a Diesel Car?
If your daily travelling is confined to intra-city, meaning you have to travel short distances, a petrol car is preferable to a diesel car. Further, if you have a budget constraint, a petrol car can be a good option. When buying a petrol car in India, other factors to consider are:
- City driving: Petrol engines often perform better in stop-and-go city traffic, where frequent acceleration and deceleration are common. Petrol cars tend to have smoother and quieter operations in urban settings.
- Initial cost: Petrol cars generally have lower upfront costs compared to diesel cars. If you're on a budget or don't plan to keep the car for an extended period, a petrol vehicle may be a more economical choice.
- Short-term ownership: If you change cars frequently, the higher resale value of petrol cars in some markets may be more advantageous.
- Availability of refuelling infrastructure: In areas where petrol stations are more prevalent or convenient, a petrol car may be a more practical choice.

An important note here. When buying a petrol or diesel car in India, securing car insurance is crucial as it is mandatory by the Motor Vehicles Act of 1988. It provides financial protection against accidents, theft, and damage, safeguarding your investment.
Having car insurance also saves you from hefty traffic fines, license suspension and even legal trouble.
