Compare Petrol vs Diesel vs LPG vs CNG cars

When deciding to buy a car, in today’s market you have 4 variants: petrol, diesel, LPG and CNG. Which one you should buy depends on some basic factors:

• Cost of vehicle
• Mileage
• Running cost (what you spend on travel per km)
• Insurance
• Maintenance
• Re-sale value
• Fuel availability

A CNG car may be the cheapest variant of them all & its low running cost could save you some bucks, but keep in mind that CNG cars do not have great re-sale value. Diesel cars are the ones which have the best re-sale value & are ideal for those who wish to have the same car for 5 or more years, using it to travel approx. 1,000kms each month. This applies to an LPG car too. However, if you love buying a new car every second or third year, the petrol variant is best as it would incur less costs than a diesel or LPG variant.
