The candid answer for this question is neither.Petrol is much refined oil compare to diesel.Diesel engines are very technologically advanced as it not uses spark to ignite the fuel and diesel engines gives more mileage .
Petrol and Diesel has their own environmental impacts .Quantity of CO2 emission is more in petrol car adding significant quantity to world's green house gas.Diesel emit less co2 (Since mileage is more)but it emits more nitrous oxides(Acid rain causing gas) .Petrol emit more carbon monoxide(highly toxic and effects blood circulation ) compare to diesel.Diesel engine releases Particulate matter(Lung cancer causing) where petrol release nill.
Conclusion is petrol has effect on global warming and diesel has detrimental effect on local environment and human health issues.But new diesel engines are trying honestly to reduce the emission level of above mentioned hazardous gases .
The best solution for this is hybrid car like "Toyota Prius" which runs on both petrol and battery.At lower speeds it runs on battery saving fuel and no gas emission in tandem.At the higher speeds it uses fossil fuel.
It suits for ride in cities as well as outside the cities.
The bigger advantage is in cities like Bangalore one cannot drive car on higher speeds because of traffic ,so hybrid car uses electric energy inside the cities most of time resulting in no sound pollution ,no air pollution and finally enhanced mileage.
Cost of Toyota Prius is approx 30 lakhs
