Petrol or Diesel or CNG Car. Best Fuel Choice for Car in 2022

Car Buying Calculator basis Average Monthly Driving of 500 to 1000 to 1500 to 2000 Kms a Month. Is it Petrol or Diesel or CNG Car for Maximum Savings

 

Petrol or Diesel or CNG Car in 2022

Buying a car is an important decision - not only it reflects taste, style, aura and top of it the convenience - but it also is a big financial decision - thanks to high ownership cost of cars in India. However, before making a Purchase Decision - its important to choose and consider :-

  • What do you give Most Importance to ? Performance or Boot Space or Mileage ?

 

  • What is your Average Running. Is it in City or Highway or Maximum Local Usage ?

 

  • Are you seeking performance or ready to compromise loss of power in CNG by having Lower Running Cost

 

Answer is

When Should not go for CNG

1. If you seek Boot Space for Luggage then do note that CNG Cylinder leads to almost filling up of 80% Boot Space in Hatchback and near around 60% in Sedan Cars. So if you seek boot space for carrying out luggage then CNG may not be ideal for you

2. CNG is for people who love relaxed Drive. Been there is Power Loss to tune of 15% due to CNG - dont expect much for Enthusiastic Drivers. Only if love Relaxed Drive then go for CNG

3. If you do Frequent Long distance trips of more than 300 Kms then CNG has limited range and most of the highways still do not have provision for CNG Filling

4. CNG Refilling Center are heavily jammed in Delhi due to relative limited stations and network. So if dont want wait times for refilling CNG then may avoid

Anyhow - you choose - think of your monthly running - ownership costs - Vehicle Performance - NVH Levels - so that you can make up the best buy

 

 

Fuel Prices n Mileage in India

Below are Present Prices of Fuel in Delhi

» Petrol: Rs 95 / Litre

» Diesel: Rs 85 / Litre

» CNG: Rs 60 / Kg (Average Rate of Commercial CNG in most of the cities)

 

Average Running - 500 Kms / 1000 Kms / 1500 Kms / 2000 Kms a Month

Below is higher amount to be paid for buying Diesel / CNG over Petrol Car (upfront cost price difference)

  Diesel Factory Fitted CNG or Manufacturer Recommended CNG
Additional Upfront Costing Over Petrol Car Rs. 1.25 Lakh approx Rs. 75,000 (CNG Kit)
Additional Finance Interest Cost at end of 5 year Rs. 35,000 approx Rs. 13,000
Higher Maintenance over period of 5 Years including one time clutch Plate & Battery change price difference Rs. 25,000 approx Rs. 7700
Additional Insurance Premium in 5  Years Rs. 15,000 Rs. 8000

 

Costing

» Buying a Diesel Car is most expensive - which will cost around Rs 2 Lakh higher in Ownership cost as against Petrol Car

» CNG Car Costs good Rs 1 Lakh higher over the Petrol Car

 

Lets Take Realistic Scenario of Using a Car in City Use Condition where most of the Vehicle Owners use

 

  Petrol Diesel CNG
Average Mileage (City) 13 Kmpl 16 Kmpl 20 Km/kg
Fuel Price Rs 95 / Litre Rs 85 / Litre Rs 60 / Kg
Running Cost Rs 7.4 / Km Rs 5.3 / Km Rs 3 / Km

 

So it will depend on your Average Yearly Usage. If your Average yearly City Usage Running is 5000 Kms then :-

  Annual Running Cost of Car (Amount in Rs)  
Kms Usage Petrol Car   Diesel Car CNG Car
5000 Kms 37000 26500 15000
7500 Kms 55500 39750 22500
10000 Kms 74000 53000 30000
15000 Kms 111000 79500 45000
18000 Kms 133200 95400 54000

However, there are 

  • Higher Insurance Premium for Diesel Cars
  • Higher Upfront Cost for CNG and Diesel Cars which has Interest Outflow
  • Higher Service Maintenance Cost for Diesel Cars and marginally higher Service Cost for Petrol Cars too 

so that also needs to be factored in before considering Petrol or Diesel or CNG Car

 

Car Buying Feasibility Purchase (Petrol or Diesel or CNG Car)

» Less Driven Cars: If Running Less than 500 Kms a Month (5000 to 7000 Kms in a Year) - Its Viable to choose Petrol Car without giving a second thought to it.

» For Average Driving: For Running in between 800 to 1000 Kms a month (10,000 to 12,000 Kms a year) - CNG Can Prove as Most Economical on Longer Term

» For Moderate Driving: Monthly Running of 1200 to 1400 Kms (15,000 to 16,000 Kms a Year) - CNG is Ideal and can help in recovering in 

» For High Running: Diesel is recommended if your average running is 2000 Kms or more in a month (i.e 20000 Kms or more in a year) - it will save you good Rs. 30,000+ a year in terms of fuel costs and can cover upfront costs and higher maintenance within 5th year - giving long term fuel efficiency and savings

 

Pros & Cons (Fuel Type)

Lets know the Pros and Cons of buying a Petrol Car against Diesel or CNG or LPG Fuel in India

  Petrol Cars Diesel Cars CNG Cars
Pros Petrol Cars are Priced Lowest among Diesel, CNG or LPG as not fitment is required Low Running Costs are main motivator Lowest Running Costs across all Sort of Models
  Engine Performance does not get degraded. Lowest NVH - Noise Vibration and Harshness Proven in Long term to owe a Diesel car as against CNG or LPG Clean Natural Alternate Fuel. Go Green Gas, ideal - if you care for Environment
  Ideal as no modification required of Alternate Gas Kit - considered also the lowest among Maintenance Pep, Power Delivery in Diesel Car is much better as fuel combustion is pretty fast leading to enhanced pickup Retro Fitted CNG Kits are there where car can run on both modes Petrol or CNG
     
     
Cons Highest Running Costs. Expensive in terms of Fuel costs on longer term High Upfront Payment, Expensive to tune of 1 Lakh - 1.5 Lakh as against Petrol cars Been CNG Cylinder Capacity is small to maximum 12 Kg with 85% Utilisation, Expect around 200 Kms run with CNG Full
  Has relatively lower Pep (Torque) in Engine Performance as against its Diesel counterpart Spare Parts and Periodic Maintenance is higher on longer term basis CNG Leads to loss of Power giving lesser pickup. A general trend is 15% - 20% drop in power based on Car and CNG Kit
    Higher NVH - Noise and Vibration levels as against Petrol Cars Eats up Boot Space due to Size of CNG Kit
    Concern on Future of Diesel Cars as ban already imposed on Diesel Car Plying > 10 years in Delhi Few Fuel Stations of CNG. Also, the time taken to refill CNG due to Paucity and Commercial Vehicles Queue
      Long Term reliability in terms of Hassle Free Ownership is yet a question if CNG Fitment is not Factory Fitted
