Posted by Pankaj Prasad In my opinion/calculation, if you drive 700/800 kms per month & keep the car for 3 years, diesel is more economical - else petrol should be preferred. Normally, the average holding of a car is more than 5 years (not sold before that). How do you calculate that? Lets say that you drive the car for 12000 kms per year. Assume a petrol price of 50 Rs. and assume Diesel at 35 Rs, difference of Rs. 15 per litre. Assume that the fuel efficiency of Petrol and Diesel engine is same (both 1.4 liter engines) = say worst case = 12 kmpl each. The better the fuel efficiency, the less the saving due to diesel v/s petrol mind you. This means this will need 1000 litres of petrol or diesel per year. This means a saving of Rs. 15000 per year only, or Rs. 45000 per for 3 years, Rs. 75000 for 5 years. Even the difference between Skoda Petrol and Diesel is 80K rupees, not mentioning that the maintenance costs with diesel will be 50% more than the petrol over 5 years. So really the diesel is not worthwhile, unless you drive at least 25000 kms per year.
