    @ Siddharth | Diesel is better but with current policies, diesel vehicles can be reduced to an extent.So, resale value gets reduced for diesel compared to petrol.In terms of driving pleasure definitely diesel is better. But petrol is environment friendly and also better in terms of engine noise.

    "Hi,While other things are subjective there is one thing here that is not right. Petrol engines are not cleaner than diesel it is the diesel that is more efficient and clean. The recent changes have come based on different debates about this question.All European cars used to be petrol with some brands never offering diesel variants. Then it was found that diesel is efficient and cleaner than petrol and this brought about the major shift which the carmakers went with when changing to Diesel.The thing is that diesel is on standard terms less harmful as the exhaust contains only one harmful thing which is PM.A Petrol Engine engine gives out quite a few pollutants and there are carcinogens present in the fumes too. A catalytic converter is used to treat the exhaust from the engine to refine it and reduce the noxious gasses and pm levels to lower than allowed max levels to keel it running. Even the catalytic converter in itself causes pollution and has carcinogens too as it degrades with time.A diesel engine runs cleaner than a petrol engine without having to use a catalytic convertor. This is the kind of flip flop which takes place with everything and the perception around it. Diesel came in because of efficiency and not for the mileage or cheaper fuel because the luxury sedans are not bought by people looking at a mileage or how much they'll save running a diesel because of price. The prices are not different in other countries.What changed is that now they started a witchhunt about diesel and advocated petrol as per claims diesel is very polluting. This is only partly true because diesel has particulate matter in the exhaust but that is the only harmful thing in it while a petrol engine has harmful gases and other carcinogens which are reduced using a catalytic convertor and this new approach has led to the decision of our courts to define a healthy life of a vehicle. A vehicle's health depends on everything other than its age. But the courts ordered that limit be based on years and also incorrectly ordered that diesel will run for only 10 yrs.I have a very good example of the reason I'm pointing it out here. I have a 2010 mid-December Tata Vista Quadrajet, the Aura plus variant that is BSIV compliant. I bought the diesel because I knew I would be travelling out of the station every other day and thus chose to go for the diesel because of the price difference matters in that case. One of the answers above has actually put it across that diesel makes sense if you drive 60-70 km per day. Because if you don't run that much the price difference as well as the better fuel efficiency will not be enough to justify the higher price you will pay for diesel. As the prices are much higher. My car has done 70000 plus km in total even with the outstation trips every other day. So if I had not overestimated the running of my car it would have been cheaper to buy a petrol car and the money I would have saved would have been enough to run my car for more than a year on petrol.Now, my point is that my car is old by its date of purchase but at 70000 plus km on it would it be better than a car that did 300000 in 3 yrs or better? Its a no brainer that my car would be better as the engine and parts would not be as worn out as a 300000 km done car. It will be cleaner and healthier for sure.The law is based on logic, not perception.How did they decide that diesel should only run for ten years and petrol for 15? What data is this decision based on except some probably interested parties who come up and paint something black for their betterment?In fact, I remember that certain experts in the sciences dealing with environmental protection or anything related had conducted a study in Delhi where they recorded pollution levels in some generally crowded areas in different parts of Delhi. They then checked what the difference came to on days that are govt holidays or when there were restrictions not allowing heavy traffic into Delhi they expected to find a big difference as they were going with the idea the pollution is not due to private vehicles but because of the heavy vehicles going through every day and thus would reduce drastically whenever it is an off or closure of heavy traffic like trucks and trailers etc.They were surprised to see that there was hardly any difference and the little they could see would also be on account of less number of Pvt vehicles on the road.This actually put the argument and debate to rest and proved this idea that heavy vehicles are the cause because they use diesel. The procedure laid down by the law was that your first registration is valid for 15 years but that doesn't mean my car is going off the road to a junkyard. We have to go to the RTO and get our car inspected and the inspector then comes and checks various aspects like the safety features, physical condition etc of the car and if you keep your vehicle well you would get an extension on your existing registration for another few years but not fifteen but generally 5 yrs.There was nothing wrong with it and it is logical because this system was made by the people who introduced us to these conveniences of civilised society.

    @ Amit | Which one you own?? Diesel or petrol??

    It was a diesal car. I sold it off as I don't keep cars more 3 years or 1 lakh km. Now I have TATA TIGOR which is another awesome car, I really admire tata cars after owning honda, maruti, mahindra(XUV 400 is another fav vehicle which I owned previously). don't have a second opinion if you want to purchase a tata car or mahindra XUV 400. Thouygh I don't feel quite good about other models of mahindra

    Suggest to buy Petrol, as diesel cars face the risk of banning in future, whichever day the polution in NCR is high. In case your are not living in Delhi and less likely to drive to Delhi may go for Diesel.Also please see my earlier post on same topic wherein I have compared operating cost (fuel saving) verses difference in price of Diesel and Petrol.
